    The ilmenite-type CoVO3 undergoes an antiferromagnetic transition below 140 K, and the tetravalent vanadium ions form V–V dimers below 550 K. This paper presents the magnetic spin structure and the phase transition induced by a magnetic field in CoVO3. Neutron powder diffraction at 50 K reveals that the spins of Co2+ arrange in a zigzag order on the honeycomb lattice with no external magnetic field. This magnetic spin structure does not exhibit spontaneous magnetization, corroborating previous magnetic measurements. Magnetization measurements in a pulsed-magnetic field revealed a transition to a weak-ferromagnetic phase at 37 T (100 K) and above 50 T (4.2 K), with spontaneous magnetization approximating 0.3–0.5 μB/f.u. This phase transition could potentially be attributed to a transition to a canted antiferromagnetic phase, which is brought about by the reduction in structural symmetry due to magnetostriction.

    Abstract The structures of cold-compressed basaltic glass were investigated at pressures up to 18 GPa using in situ X-ray and neutron diffraction techniques to understand the physicochemical properties of deep magmas. On compression, basaltic glass changes its compression behavior: the mean O-O coordination number (CNOO) starts to rise while maintaining the mean O-O distance (rOO) above about 2–4 GPa, and then CNOO stops increasing, and rOO begins to shrink along with the increase in the mean coordination number of Al (CNAlO) above ~9 GPa. The change around 9 GPa is interpreted by the change in contraction mechanism from bending tetrahedral networks of glass to increasing oxygen packing ratio via the increase in CNAlO. The analysis of the oxygen packing fraction (ηO) under high pressure reveals that ηO exceeds the value for dense random packing, suggesting that the oxygen-packing hypothesis recently proposed cannot account for pressure-induced structural transformations of silica and silicate glasses. The rise of the CNOO at 2–4 GPa reflects the elastic softening of fourfold-coordinated silicate glass, which may be the origin of anomalies of elastic moduli in basaltic glass at ~2 GPa previously reported by Liu and Lin (2014). The widths of both the first sharp diffraction peak and the principal peak show contrastive compression behaviors between modified silicate and silica glasses. This result suggests that modified silicate glasses represent different pressure evolutions in the intermediate- and extended-range order structures from those of silica glass, likely due to the presence of modifier cations and the resultant formations of smaller rings and cavity volume.

    <title>Abstract</title>The high-pressure phases of oxyhydroxides (δ-AlOOH, ε-FeOOH, and their solid solution), candidate components of subducted slabs, have wide stability fields, thus potentially influencing volatile circulation and dynamics in the Earth’s lower mantle. Here, we report the elastic wave velocities of δ-(Al,Fe)OOH (Fe/(Al + Fe) = 0.13, δ-Fe13) to 79 GPa, determined by nuclear resonant inelastic X-ray scattering. At pressures below 20 GPa, a softening of the phonon spectra is observed. With increasing pressure up to the Fe3+ spin crossover (~ 45 GPa), the Debye sound velocity (<italic>v</italic>D) increases. At higher pressures, the low spin δ-Fe13 is characterized by a pressure-invariant <italic>v</italic>D. Using the equation of state for the same sample, the shear-, compressional-, and bulk-velocities (<italic>v</italic>S, <italic>v</italic>P, and <italic>v</italic>Φ) are calculated and extrapolated to deep mantle conditions. The obtained velocity data show that δ-(Al,Fe)OOH may cause low-<italic>v</italic>Φ and low-<italic>v</italic>P anomalies in the shallow lower mantle. At deeper depths, we find that this hydrous phase reproduces the anti-correlation between <italic>v</italic>S and <italic>v</italic>Φ reported for the large low seismic velocity provinces, thus serving as a potential seismic signature of hydrous circulation in the lower mantle.

    More details Close

    The Pacific coast of Tohoku District in Northeast Japan (Iwate, Miyagi, and Fukushima Prefectures) was seriously damaged by a violent tsunami resulting from the 2011 off the Pacific coast of Tohoku Earthquake on March 11 2011. The disaster area was covered by tsunami sediments, which are mainly marine sediments. We collected 137 tsunami sediments from Kuji City, Iwate Prefecture through to Minamisoma City, Fukushima Prefecture (40°11′N, 141°58′E to 37°43′N, 140°51′E). Analysis of bulk sediment chemistry and leaching test by pure water and seawater were carried out to access arsenic contamination. In addition, chemical forms of arsenic in different size fractions (<3 kDa, 3 kDa to 0.2 μm, 0.2 μm to 0.45 μm, and ≥0.45 μm) from the leachates were investigated by filtering techniques.<br>Arsenic concentrations in the pure water leachates of 45 samples had higher arsenic levels than the Japanese Environmental Quality Standards for Soil Pollution (10 μg/l). In particular, tsunami sediments from the Ohya area in Kesen-numa City, Miyagi Prefecture, had arsenic levels 39 times greater than this threshold, reflecting the influence of gold mines in this region. The fraction of arsenic species < 3 kDa in size in leachates of the high arsenic samples was ca. 70%, indicating that most of the arsenic in the leachates is present as fine colloidal particles and/or dissolved species.

    An ε-FeOOH is one of important hydrous minerals to carry water into deep mantle. In order to understand the elastic property, we measured elastic wave velocities and densities of high-spin ε-FeOOH up to 18.5 GPa simultaneously. All the experiments have been conducted at BL04B1 in SPring-8 using a combination of the ultrasonic pulse-echo-overlap method and Kawai-type multi-anvil apparatus. Under the experimental condition, the velocities are about 5 % and 15 % lower than those of low-spin ε-FeOOH and δ-AlOOH, respectively.

    Flux of subducting continental crust is determined by strength of continental crust which is possibly controlled by that of coesite at the deep upper mantle condition. Pressure condition of previous study on coesite rheology (Renner et al., 2001) was limited to 4 GPa. Here, based on in situ uni-axial deformation experiments of coesite conducted using D-DIA and D111 apparatuses at the synchrotron beamline NE7A, PF-AR, KEK, we report rheological property of coesite at pressure of 2-9 GPa.

    The compression behavior of distorted rutile-type hydrous minerals has attracted much interest because of their high stability under high-pressure conditions. We performed an X-ray diffraction experiment of synthetic guyanaite (β-CrOOH) with distorted rutile-type structure up to 6 GPa at 300-700 K. The data of P-V-T was fitted to a second-order Birch-Murnaghan EoS with following parameters: bulk modulus KT0 = 191±20 GPa, volumetric thermal expansion coefficient α = (3.3±1.5)×10-5 K-1.

    We conducted the high pressure experiments up to 6 GPa, using X-ray and neutron to analyze the structural changes of basaltic glass with increasing pressure. We obtained structure factor and radial distribution function, which indicate that the shrinkage of T-O-T bond angle causes the intermediate range structure arrangement (T = Si4+, Al3+). Moreover, structure factor of neutron diffraction suggests that compression induces intermediate range disordering and short range ordering.

    We will discuss the sulfur host in the Earth upper mantle and mantle transition zone based on the phase relationships of the Fe-Ni-S system at high pressures. The Fe-Ni-S melt would be primary S-bearing phase in the lower part of the upper mantle (250-660km). It would play important roles in the mantle chemistry such as deep carbon cycle as well as the physical properties of mantle such as the seismic wavespeeds.

    We report the result of in situ X-ray diffraction study on soda melilite (CaNaAlSi2O7) at high pressures and high temperatures. Experiments were carried out in the pressure rang of 0-6.21 GPa and in the temperature range of 300-1100K. We observed that soda melilite was formed at 2.58 GPa and 1100K. Then temperature was decreased to 300K. We observed the breakdown of soda melilite to grossular, jadeite and sodium metasilicate at 3.19 GPa and 1100K. This study showed that phase boundary locates around 2.9 GPa at 1100K.

    &beta;-GaOOH is a high pressure polymorph of &alpha;-GaOOH (diaspore structure) and is isostructural with &delta;-AlOOH. The isothermal compression behavior of &beta;-GaOOH has been studied at ambient temperature by Sano-Furukawa et al. (2012). However, they did not perform experiments at simultaneous high pressures and high temperatures. Here we report a powder X-ray diffraction study of &beta;-GaOOH up to a pressure of 14 GPa and a temperature of 700 K to determine the P-V-T equation of state.

    High-pressure X-ray diffraction study of RhOOH has been carried out at room temperature up to 16 GPa to investigate the compressibility of an oxyhydroxide with the InOOH-related structure. A fit of pressure-volume-temperature data by the third-order Birch-Murnaghan equation of state yielded isothermal bulk modulus K0 = 254(13) GPa and its pressure derivative K' = 2.2(14).

    Iron hydrite is formed in the serpentinization reaction at around 1.5 GPa and high temperature. This reaction consumes hydrogen and thus hinders formation of methane in the deep crustal and upper most mantle conditions. Thus, iron hydrite is a key for hindering formation of hydrogen, abiotic methane and thus deep life in the deep earth.

    In order to clarify the dominant deformation mechanism in the upper mantle, we have conducted deformation experiments at pressure and temperature conditions of 3.0–5.3 GPa and 1473–1573 K, respectively, using fine-grained (grain size of &sim;1 um) forsterite aggregate. The analysis of stress-strain rate data taken at dry conditions using a flow law equation yielded the activation volumes of &sim;7 and &sim;11 cm3/mol for diffusion creep and dislocation creep accommodated grain-boundary sliding, respectively. The present results implies that the diffusion creep is the predominant deformation mechanism at the most conditions of pressure, temperature and strain-rate in the upper mantle.

    Deformation experiments on hydrous melt-bearing dunite were conducted under upper mantle conditions, in order to explore the effect of intergranular fluids on the plastic flow of olivine in Earth's upper mantle. The creep strength of hydrous melt-bearing dunite was about 2 times lower than the dislocation creep strength of hydrous olivine under these experimental conditions. The strain rate was proportional to differential stress to the 2.1 power, and the differential stress markedly increased with increase in grain size. These observations show that grain boundary sliding dominated the deformation of olivine (i.e., superplasticity). Superplasticity is the dominant creep mechanism of olivine in fluid-bearing fine-grained peridotites under low-temperature and high-stress conditions

    We conducted the albite decomposition experiments at 1.1-4.1 GPa and 673-1073K under differential stresses using multi-anvil type deformation apparatus with synchrotron X-ray. Flow stresses of each phase and transformation rates were observed by time-resolved two-dimensional X-ray diffraction measurements, and axial strains were measured from radiography images of the samples. Based on the results obtained, we will discuss the interaction between the albite decomposition and plastic flow.

    The viscosity of silicate melt of NaAlSi2O6 composition was measured at pressures from 1.6 to 5.5 GPa and at temperatures from 1350 to 1880&deg;C. We employed in situ falling sphere viscometry by using X-ray radiography. We found that the viscosity of NaAlSi2O6 melt decreased with increasing pressure up to 3.6 GPa at 1780&plusmn;10&deg;C. By using the relationship between the logarithm of viscosity and the reciprocal temperature, the activation energies for viscous flow were calculated to be 3.7&plusmn;0.5 * 10^2 and 3.6&plusmn;0.5 * 10^2 kJ/mol at 2.2 and 2.9 GPa, respectively.

    Density of magma at high pressure is one of the most important properties to understand magma migration in the planetary interior and the differentiation of the terrestrial planets. The density measurements of magma have been carried out by several methods (shock compression experiments and sink-float method in static experiments, etc.). However, since these methods have difficulties in acquisition of data at a desired pressure and temperature, the density of the silicate melt have been measured under only a few conditions. Recently a new density measurement was developed by the X-ray absorption method. Advantage of this method is to measure density of liquids at a desired pressure and temperature. In the present study we measured the density of peridotite magma by X-ray absorption method. Experiments were carried out at the BL22XU beamline at SPring-8. A DIA-type cubic anvil apparatus was used for generation of high pressure and temperature. We used tungsten carbide anvils with the top anvil sizes of 6 mm. The energy of monochromateized X-ray beam was 23 keV. The intensities of incident and transmitted X-ray were measured by ion chambers. The density of the melt was calculated on the basis of Beer-Lambert law. The starting material was a crystal with the pyrolite composition. Experiments were made from 1 atm to 5 GPa, from 300 to 2100 K.

    Carbon dioxide and water are the most important volatile constituents in the Earth and they produce drastic changes in the melting phase relations and partial melt composition of the mantle peridotites. Study of the peridotite-CO2 system is closely related to petrogenesis of kimberlite and diamond. There are a few high pressure mineral inclusions (i.e. majorite garnet and Ca & Mg perovskite) in diamond which suggest that kimberlites may be originated from the transition zone and lower mantle. Several experimental petrologists have studied the kimberlite and basalt-CO2 systems, however the phase relations and melt compositions in the CO2-bearing peridotite at high pressures are poorly constrained. Simplified peridotite-CO2 system (like CMS or CMAS) has been studied at pressures up to 12 GPa (Canil and Scarfe, 1990), whereas complex peridotite-CO2 systems have investigated only at lower pressures (up to 4 GPa, e.g. Wendlandt and Mysen, 1980). In this work we report the results on the phase relations and melt compositions of a model peridotite-CO2 system determined at 10-20 GPa and temperature range from 1200 to 2100oC.Our results show that solidus of carbonated peridotite is consistent with low-pressure data for CMAS-CO2 system. Liquidus phase at 10-20 GPa is majorite garnet. At 10-15 GPa, crystallization sequence with decreasing temperature is garnet, olivine and clinoenstatite. Magnesite is the most important CO2-rich phase stable in peridotite and clinoenstatite is an important phase in carbonated peridotite at 10-15 GPa.The partial melts formed by 10-25% melting at 10-20 GPa has high MgO (26-34 wt.%) and FeO (7.0-10.4 wt.%) and low SiO2 (18-36 wt.%) and Al2O3 (0.5-1.3 wt.%) contents. It contains also 6-12 wt.% CaO, 0.6-2.0 wt.% Na2O and 0.1-0.3 wt.% K2O. The CO2 contents in the melts are 14-32 wt.%. SiO2-poor composition of partial melts is different to the results for melting of anhydrous or water-bearing peridotite. Partial melting of hydrous peridotite produce SiO2-rich melts, which can be related to komatiite magmas (e.g. Litasov and Ohtani, 2002). The composition of low degree partial melts (10%) in present experiments is close to magnesiocarbonatites, whereas higher degree melting (20-25%) produce melts, which is close to kimberlite magmas.

    Visible to near-infrared (VIS/NIR) reflectance spectra of natural pyroxenes have been measured since the Apollo projects. In general, several transition metals (Fe, Mn, Ti etc) are contained in natural samples, and these elements yield complex spectra because of the combination of absorption features from each transition-metal element. It is difficult to quantify the effects of these elements on the spectral reflectance of natural pyroxenes. For arguments of systematic spectral variations without effects of transition metals except iron, it would be useful to measure the reflectance spectra of synthesized pyroxenes. In this work, we measured the VIS/NIR reflectance spectra of pyroxenes synthesized in the MgO-FeO-CaO-SiO2 system, and compared the results with those of natural pyroxenes, in order to establish the new systematic compositional model. The all spectra show two absorption bands near 1 and 2um. We found the relations between the absorption wavelength and Fe#(=FeO/(MgO+FeO+CaO)) or Ca#(=CaO/(MgO+FeO+CaO)) and compared the results with those of natural pyroxenes (Cloutis & Gaffey (1991) and Schade et al. (2004)).

    Resent tomographic observations suggest that some subductig slabs stagnate at mantle transition zone. Irifune and Ringwood (1978) show that there is density crossover occurs at the depth 660km to 800km between MORB and peridotite, which causes buoyancy and stagnate slab or tear off upper oceanic crust at 660km. It is important to determine the depth of post-garnet transition occurs in MORB system to discuss the behavior of the slab at 660 km. In this study, we determined post-garnet phase boundary in MORB system using in-situ X-ray experiment at 20-25GPa and 1100-1200 &ordm;C under hydrous conditions.

    Density of silicate melt at high pressure is one of the most important properties to understand magma migration in the planetary interior. However, because of experimental difficulties, the density of magma at high pressure is poorly known. Katayama et al. (1996) recently developed a new in site density measurement method for metallic melts, based on the density dependency of X-ray absorption in the sample. In this study, we tried to measure the density of basaltic melt by this absorption method.When X-ray is transmitted to the sample, the intensity of the transmitted X-ray beam (I) is expressed as follows; I= I0 exp(-mrt), where I0 is the intensity of incident X-ray beam, m is the mass absorption coefficient, r is the density of the sample, and t is the thickness of the sample. If t and m are known, we can determine the density of the sample by measuring I0 and I. This is the principle of the absorption method for density measurement. In this study, in order to determine t, we used a single crystalline diamond cylinder as a sample capsule, which shows less absorbed and less deformed. So t (thickness of the sample at the point x) is expressed as follows; t = 2*(R2-x2)1/2, R is the inner radius of cylinder, and x is distance from center of the capsule.Experiments were made at the beamline (BL22XU) of Spring-8. For generation of high pressure and high temperature, we used DIA-type cubic anvil apparatus (SMAP180) there. We used tungsten carbide anvils with the edge-length of 6 mm. The energy of monochromatic X-ray beam was 25 keV and the beam size was reduced to 0.1*0.1 mm2 by 2 slits. Starting material was a glass with the MORB composition (SiO2-Al2O3-FeO-MgO-CaO-Na2O). We measured the density from 1 to 5 GPa at from 300 K to 1873K. Details of conclusion and discussion will be reported the day.

    The density of a FeO-rich peridotite melt was measured from 6.0 to 15.7 GPa by the buoyancy test. The chemical composition of the peridotite was the same as that of a model Martian mantle (SPB). Sinking and flotation of the diamond were observed at 13.8 and 14.5 GPa, respectively. The experiments using olivine as the buoyancy marker showed that the density crossover between the SPB melt and the equilibrium olivine (Fo89) exists at 9 GPa, which corresponds to a depth of 700 km in Mars's interior. <BR>The melting phase relation of the SPB composition was also determined up to 14.0 GPa. The liquidus phase was olivine up to 10.0 GPa and was substituted to garnet between 10.0 and 14.0 GPa. Since the density of garnet is higher in the Martian mantle condition, the liquidus garnet can be fractionated in the globally molten Martian mantle. On the other hand, olivine can be suspended around a depth of 700 km by its neutral buoyancy.<BR>The present study implies that olivine segregated in the bottom of the magma ocean and formed the olivine-rich layer in the Martian mantle, and that this layer can be a source region of the shergottite parental magma.<BR>

    In the experimental study of geofluid using an externally heating diamond anvil cell (EHDAC), the determination of pressure in situ is necessary. Mysen and Yamashita (2010) established a pressure scale using the Raman spectra of 13C diamond. Because we can distinguish Raman modes from 12C diamond of anvil diamonds and 13C diamond in a sample chamber. However, the pressure scale is applicable in the pressure condition of the Earth’s crust. The purpose of this study is to determine a pressure scale, which is applicable under the pressure corresponding to the upper mantle, based on the Raman spectra of 13C diamond. We set up an experimental system to collect the Raman spectra of the sample in an EHDAC. We obtained Raman spectra of 13C diamond in EHDAC up to 12 GPa, which correspond to the bottom of the upper mantle. Under higher pressure a Raman mode of 13C diamond overlapped that of 12C anvil diamond. We are now determining an equation for a pressure scale.

    To clarify the core compositions of Mercury and Mars, elastic properties of liquid and solid Fe-alloys were investigated up to the planetary core conditions. We developed simultaneous sound velocity and density measurement system under high pressure and obtained relationship between sound velocity and density. It is found that the effect of alloying elements (C, S, Si, Ni) on the elastic properties of iron shows significantly different trend depending on alloying elements. Based on these results, we estimated the composition and conditions of the planetary cores.

    Viscosity of magma and fluid is a fundamental property in volcanic processes. Therefore, viscosities of various silicate melts have been extensively measured under high pressure. However, little is known about the pressure and temperature dependence of viscosity. The viscosity measurement under pressure has been carried out using the falling sphere method. In the experiments, a metal sphere is installed at the top of the sample container. When the sample is heated above the liquidus temperature at the desired pressure, the sphere starts falling in the liquid. The falling velocity is measured from X-ray radiography movie. However, by the conventional falling sphere method using an X-ray image, we obtain only one viscosity value at a certain pressure/temperature condition in one high pressure experiment. In the present study, we developed a rotation stage for a high pressure apparatus to repeat viscometry at high pressure. We obtained pressure and temperature dependences of liquids.

We also successfully measured compressional velocity of hcp-iron to 173 GPa at 3000 K, which are the data determined at the highest pressure and temperature by the IXS method. We also determined the spin-state and magnetic properties of the iron-oxides and iron-light element compounds at high pressure. Based on these experimental results we proposed the model of the composition and the temperature profile of the core.

    惑星の内部構造やダイナミクスを理解する上で鉄合金融体の密度は基本的な物性値である。しかしながら、現在まで高圧下での鉄合金融体の密度測定は数例しか行われていない。浮沈法を用いたFe-S融体の密度測定Balog et al.(2003)やNishida et al.(submitted)で行われている。X線吸収法によるFe-S(S=10,20,and 27wt%)融体の密度測定は圧力が1.5-6.2GPa、温度が1500-1780K範囲で(Sanloup et al. 2000)によって行われている。本研究では,X線吸収コントラストイメージを用いて密度測定を行った。この方法は透過X線強度がX線吸収コントラストイメージの明るさに比例する原理に基づいており、1度の露光で試料を通過した2次元の透過X線強度の情報を得ることができるのが利点である。 本研究ではFeS融体の密度をKEK-PFのBL14C2において5GPa、1900Kまでの条件で密度測定を行った。1.3GPa、1600KにおけるFeS融体の密度は4.23g/cm^3であった。本研究で得られた1.3GPa-1600KのFeS融体の密度と4.2GPa-1573Kの密度(Chen et al. 2005)と1atm-1600Kの密度(Kaiura et al.,1979)を用いて得られた等温体積弾性率(K_T)はK'が4から6の範囲でおのおの12.3から14.6GPaであった。 本研究によって、X線イメージを用いる密度測定法が、従来のX線吸収法の限界であった圧力を大幅に拡大できるものであることが明らかとなった。

    In this research project, we investigated the phase relation of the minerals under the lowermost mantle condition and the chemical reaction between those minerals and molten iron up to the condition corresponding to the earth's core-mantle boundary. For realizing such extreme conditions, we newly designed a symmetrical diamond anvil cell with a wide conical window for laser-heating and optical spectroscopy. The laser-heating system was also refined for stable heating and optimal temperature measurement from the hot sample by a spectroradiometric method. Experiments were performed using these techniques at SPring-8 and Photon Factory for in-situ X-ray diffraction measurements at high P-T, and also at laboratory for recovery runs to check the quenched samples. Thanks for the recent advances in micro-processing technologies such as laser cutting, focused ion beam, we successfully prepared the thin section of the recovered samples for analytical transmission electron microscopy. Finally we obtained the following results. (1) The chemical reaction between molten iron and perovskite and post-perovskite phase and wetting property at the core-mantle boundary condition was examined, and silicon and oxygen turned to be important candidates as light elements in the outer core. The wetting angle between post-perovskite phase and molten iron was slightly higher than the critical angle of 60°, which means 2wt% of the core material can be trapped in the D" layer. (2) Magnesiowustite is the heaviest minerals overall the mantle based on the iron partitioning experiments between magnesium oxide and silicate perovskite and post-perovskite phase. No evidence for the effect of a high-spin to low-spin transition was found in these minerals. (3) Potassium can be dissolved into molten iron significantly at core-mantle boundary condition, and the element may work as a heat source in the core. (4) The hydrous mineral, delta-AIOOH, has a wide stability field over 100GPa and 2000K, therefore this phase at relatively low temperature condition in descending slab possibly survive to the lowermost mantle to supply the water to core-mantle boundary. (5) Potassium bearing silicate with post-hollandite structure can be stably exist at the lowermost mantle condition.

    Density of magma is one of the important physical properties to control the transportation of magma in the Earth and planetary interiors. We have established the new technique to measure the density of magma under pressure by using large volume high-pressure apparatus and synchrotron radiation, on which X-ray absorption is based. We have measured the density of mid-ocean ridge basalt (MORB) magma up to about 5 GPa and 2000K by suing high-pressure X-ray absorption technique, which is the most abundant magma on the Earth and the Earth-like planets. Experiments were carried out using the cubic press, SMAP1, installed at BL22XU of SPring-8, where a highly brilliant monochromatic X-ray is available. The basaltic magma was confined in the single crystal diamond capsule that is X-ray transparent rather than silicate, the hardest material, which is uniformly deformed under pressure, and chemically inert with magma. Absorption of X-ray from the basaltic magma was measured up to 4.6 GPa and 1900 K, and density was calculated from Lambert-Beer law, I = I_0exp(-μpt). X-ray absorption measurements give the density of basaltic magma along its melting curve. Fitting the Birch-Murnaghan equation of state to density data yields anomalous negative pressure derivative of the bulk modulus of the basaltic magma. This means the basaltic magma becomes more compressible at higher pressure, opposite to the normal crystalline solid. This result strongly indicates that the structure of basaltic magma is changing with increasing pressure, including the shrinkage of networks of SiO_4 and AIO_4 tetrahedra and the increase of the coordination number of aluminum ions.

    本年度は、木星・土星の主成分と考えられる水素-ヘリウム系の混合ガスを使った高圧実験を行った。初期組成でH_2:He=1:1及びH_2:He=3:1の混合ガスを用意し、昨年度開発したダイヤモンドアンビルセルにガス試料を充填した。各試料について高圧下での相変化を顕微鏡下で観察し、各相のラマン散乱測定を行った。顕微鏡下の相変化観察では5.8GPaから均一流体相が水素濃集相とヘリウム濃集相の二流体相に分離し、6.5GPaで水素濃集相が固化する様子が観察された。更に加圧を続けると、ヘリウム相に対する水素溶解度が低下によると見られる、水素濃集粒子が内部に析出するのが見られた。ラマン散乱の結果からは、水素分子の伸縮運動に対応するQ1モードの圧力シフト、転移に伴う周波数の不連続変化が見られ、ヘリウム濃集相中のQ1が12.9GPaで消失する事が分かった。これは、顕微鏡観察では確認できなかったヘリウム濃集相の固化に対応すると考えられ、これらの測定はH_2:He=1:1の試料で30GPaまで、H_2:He=3:1の試料で17GPaまで行われた。以上から、固化したヘリウムに対して水素は殆ど溶解せず、高圧下では固体二相に分離すると考えられる。また、H_2:He=1:1とH_2:He=3:1の試料では、ラマンの圧力シフト量及び勾配が異なり、ヘリウム濃度依存を確認したが、過去に報告のある組成とラマンシフトの関係式とは一致しないことが分かった。本研究の結果は、過去に報告のある12GPaまでのデータに比べ2倍以上の高圧力まで観測を行い、ヘリウム固体相に対する水素の固溶量が検出限界以下であること、ラマンシフトの組成依存に関し再較正が必要なことを示した点で新しい。以上の結果は2006年度地球惑星科学関連合同大会及び、国際鉱物学会議(IMA-神戸)で報告されると共に、国際誌への投稿を準備中である。

    In this study we clarified the reactions occurring at the Core-Mantle boundary and structure and properties of the Earth's Core using two types of apparatuses such as a diamond anvil cell and multianvil apparatus. The results can be summarized as follows : 1.We clarified the reactions between metallic iron and water up to 84 GPa and high temperatures. At pressures above 10 GPa and temperatures above 1000K, Iron and water react to form iron hydrite and iron oxide. This reaction is important during the core formation stage and at the present core-mantle boundary. This result implies that hydrogen can be incorporated into the Earth core. 2.We have studied experimentally the reactions between metallic iron and perovskite and post-perovskite in the pressure range from 30 to 135 GPa at 3000 K which is the real Core-mantle boundary condition. We observed formation of magnesiowusite and dissolution of Si and 0 into the molten iron under the present pressure and temperature conditions. The solubility of these elements increases with increasing pressure and temperature significantly. 3.We studied the dissolution of potassium into the molten iron under the Core conditions of 135 GPa and 3500 K. Molten iron dissolves potassium about 0.8 wt. %, and the present results showed at first that the core can contain radiogenic potassium and can produce some radiogenic heat.

    火山爆発の準備過程において、密度がマグマの上昇を左右する最も重要な物性である。 本研究においては、玄武岩マグマについて、高温高圧下における粘性係数、密度と弾性率、そして構造を、SP8に設置された高圧装置をもちいて、高温高圧での放射光を用いたX線撮像法、X線吸収法、そしてX線回折法を駆使することによって明らかにした。具体的には(1)海洋底玄武岩(MORB)組成のマグマの粘性係数を約5GPaまで測定した。そして2-3GPaに粘性係数の最小が存在することを世界に先駆けて明らかにした。このような粘性係数の挙動は、高温高圧のもとでマグマの構造が変化することを示唆している。また、水2wt%を含む玄武岩マグマの粘性係数を5GPaまで測定し、含水条件ではマグマの粘性が大きく減少し、無水マグマに認められた粘性の最小が存在せず、圧力とともに粘性係数が増加することを示した。(2)放射光X線の吸収を測定することによる密度測定法を開発し、圧力1GPaおよび3GPa、高温の条件での玄武岩組成のガラスおよびマグマの密度の測定に成功した。X線吸収法によってマグマの密度を測定した最初の例である。さらに、(3)SP8設置のマルチアンビル高圧装置を用いて約1GPa及び3GPaの条件で、X線回折法によって、ガラスおよびマグマの構造の決定を試みた。まだ予備的な実験結果であるが、1GPaと3GPaのマグマの構造が異なることを見出した。1GPa高温のマグマに比較して、3GPaにおいてはSiまたはAlの局所構造が変化し、配位数の増加する傾向が認められた。この結果は、上記の密度と粘性の変化の様式と矛盾しない。上記のようなX線その場観察法とともに(4)含水マグマの密度をダイヤモンド結晶の浮沈法によって明らかにした。水2wt%を含む海洋底玄武岩マグマの密度を約17GPaまで測定し、マグマ中の水の部分モル体積を決定した。これによると、上部マントル最下部では、水2wt%程度を含むマグマは上部マントルの岩石よりも重くなり、ここに含水マグマが安定に存在する可能性がある。

    We have developed techniques on high-pressure generations using sintered diamond multi-anvil systems combined with synchrotron radiation, which enables to obtain time-resolved X-ray diffraction data every 10-30 seconds up to 35 GPa and 2000K. We also tested new sintered diamond anvils manufactured by Ringwood Superabrasives for the X-ray window of multi-anvil apparatus. Based on these techniques, we have quantitatively studied on kinetics of post garnet transformations in natural garnet, high-pressure transformations in pyroxenes (enstatite and diopside), and effects of water on the olivine-spinel transformation kinetics. Transformation microstructures and water contents of samples recovered were examined using TEM and FTIR. In addition to these studies, we have also examined about formation of metastable cubic perovskite, dehydration reaction of high-pressure hydrous minerals, and mechanisms and kinetics of high-pressure transformations in shocked meteorites, those have important implications for subduction processes. Cation diffusion kinetics in wadsleyite have been experimentally examined and rheology of subducting plates and mantle transition zone was discussed. We have extrapolated quantitative kinetic data obtained to subduction zone conditions and construct metastable mineralogy in subducting plates. We have calculated the density of subducting slabs taking transformation kinetics into accounts, which suggests that the subducting slabs are buoyant at the top of the lower mantle due to the presence of metastable low-pressure phases. Grain-size reductions caused by non-equilibrium transformations can reduce strength of subducting plates. These are important for the formation of stagnant slabs at the top of the lower mantle.

    コマチアイトマグマは数GPa程度の圧力に相当する深さで生じ、そこから地表へ噴出したと考えられている。本研究においては、コマチアイトマグマなどの超塩基性珪酸塩融体の密度をマントル遷移層の深さに相当する圧力下までの測定に成功した。実験には我々が手法を確立した結晶浮沈法を用いた。その結果、マントル遷移層ではコマチアイトマグマは、マグマと共存するガーネットの密度と等しくなることが示された。このことは、マグマが分離するための条件を規定する上で、極めて重要な重要な結果といえる。 一方、粘度測定に関しては、無水コマチアイトマグマの粘度を7GPaまでの圧力下で測定することに成功した。実験にはX線影像落球法を用いた。これに際しては、高速X線CCDカメラを使用することにより、低粘度融体の測定を可能とした。実験の結果、溶融温度に沿った温度圧力条件におけるコマチアイトマグマの粘度は、圧力の増加とともに増加することが示された。このことは、低圧側ほどマグマは流動性に富むことを意味しており、これを踏まえたマグマの生成・噴出モデルを考える必要がある。さらに、コマチアイトの主要端成分であるdiopside組成融体の粘度測定を13GPaという超高圧下で行った。これは、現在のところもっとも高温高圧力下での測定記録となっている。このdiopside融体に関する実験の結果、粘度は始め圧力の増加とともに増加するが、10GPaを超えた辺りで減少に転ずることが示された。これは、先に行われた拡散係数測定からの推測とは調和的である。しかしながら、diopside融体のような非重合性融体では圧力の増加とともに粘度が単調に増加するという、従来の推測とは矛盾するため、コマチアイトマグマなどを用いて、より詳細な物性測定や構造解析などを行うことの重要性が増すこととなった。

    本研究においては、星間空間や炭素質コンドライトのなかの有機物として認められるケロジェンおよび有機物PAHであるコロネンの高温高圧下における安定性を明らかにした。コロネンの安定領域はダイヤモンドアンビルおよびマルチアンビルを用いて、2-6Gpaの条件で1000Cまでの高温で明らかにした。その結果、6Gpaで数100Cの条件で回収した試料の質量分析計による測定によって、この試料中では、コロネンの二量体であるジコロニレン、三量体などの重合体が生成することを明らかにした。この多量体のラマンスペクトルと赤外吸収スペクトルの測定を行い、振動のモードを同定することができた。この実験結果は、宇宙塵や彗星などに含まれるコロネンは木星や土星の衛星の内部の温度圧力条件で重合してジコロニレンなどの多量体が安定に存在する可能性があることを明らかにした。 さらに、上記の有機物とともに、揮発性の物質の代表として、硫化マグネシウムと水の系のそう関係を、ダイヤモンドアンビルを用いて明らかにした。この系の溶融関係を約2Gpaまでの圧力で明らかにした。その結果を用いてエウロパやガニメデなどの氷衛星の内部状態を推定した。

    We developed the laser heated diamond anvil cell system and sintered diamond multianvil systen, which enable us to generate high temperature up to above 2000 K at around 100 GPa, and 3000K at pressures above 30 GPa. Following results are obtained by using these systems ; (1)We confirmed that (Mg, Fe) O with a NaCl structure up to 100 GPa and 2000K, (2)Compression curve of FeH has been clarified, and we found that FeH become incompressible at pressure above 50 GPa, which may be caused by the electromagnetic transformation. Incompressible nature of FeH at high pressure suggests that the H content explaining the density deficit of the core is 1/3 of that estimated previously, (3)We determined the compression curves of FeSi alloys up to 200 GPa. The low density and high incompressibility of FeSi alloys are consistent with the physical properties of the core, and this indicates that Si is also a plausible candidate for the light elements of the core, (4)We clarified the reaction of Iron and silicate up to 80 GPa and 3500K and found that some Si and O are dissolved into the metallic iron in this condition, (5)We clarified the kinetics of post-spinel and post-garnet transformations, and applied the results for subducting plates into the lower mantle, (6)We determined the maximum water content in wadsleyite and ringwoodite, magnesiowustite, and perovskite, and estimated the water storage capacity of the transition zone and lower mantle.

    Study of water, methane, ammonia, and their mixtures under supercritical conditions at high pressure and temperature is essential not only for Earth and Planetary Sciences but also for Chemical Engeneering. In order to investigate these topics, we introduced a new diamond anvil cell apparatus with the system which can measure the FTIR spectra at high pressure and temperature. For the anvils of the present diamond anvil cell, we used the synthesized type II diamonds, Sumi crystal, which contains very low impurity and suitable for the present purpose. We combined the new diamond anvil cell with the micro-FTIR spectrometer (JASCO CO.LTD). We applied an external heating system made of Pt wire for the diamond anvil cell We studied stability of coronen and kerogen which are observed in the cometary bodies and the primitive chondritic meteorites in order to investigate the role of organic materials in planetary interior. Present experiments revealed that coronen is stable in the pressure range from 1.3 to 3.3 Gpa and temperatures up to 300C, whereas kegogen is stable at least up to 9 Gpa at room temperature and decomposes at temperatures above 250C at high pressure. The present results indicate that these organic matters are stable in deep interior of some icy satellites.

    In this research, we investigated the properties on some major mantle minerals under high pressure and high temperature using an improved double-sided laser heated diamond anvil cell (LHDAC). The results of this research are followings; (1)We newly developed a laser heating system at Tohoku University, which enable to heat the larger sample stably under pressure. The technical essences were feed backed to construction of in-situ X-ray diffraction system using LHDAC in both Photon Factory and SPring-8. (2) The reaction between iron and silicate perovskite was examined for the pressure range of 30 - 60 GPa. A possibility of reaction which produce iron silicide was detected in the recovered sample after laser heating at 30 GPa. The texture recovered from 60 GPa and 2800 K show a percolation of molten iron into the grain boundary of silicate perovskite. (3) High pressure and high temperature behavior of (Mg,Fe)O was examined using in-situ X-ray diffraction method with synchrotron radiation. A rhombohedral distortion was observed in all compositions. High temperature phase at around 100 GPa has rock salt structure and no NiAs-structured phase was observed except for the end member of FeO. Therefore, the stable phase under the lowermost mantle condition should have rock salt structure. (4) Post stishovite phase of Si0_2 was examined using in-situ X-ray diffraction method. CaCl2-structured phase was observed above 55 GPa, which was stable up to 80 GPa and 2000 K. The results show that the Clausius-Clapeyron slope of this transition is slightly positive. (5) Iron-water reaction was examined using in-situ X-ray diffraction method. The bcc iron directly reacted with water to produce iron hydrate and showed successive transition to iron hydride and wustite at higher temperature. The fcc iron reacted to produce iron hydride and wustite after laser heating. These iron hydride were unquenchable to ambient condition.

    氷衛星などの天体の内部構造とテクトニクスについては不明な点が多い。氷天体の原材料物質は、水、メタン、アンモニアなどの化合物である。一方、原始的な隕石中にはケロージェン様の有機物が存在する。これらの有機物も氷天体の構成物質として無視できない。この研究ではダイヤモンドアンビル高圧装置に外熱用の白金のコイルヒーターを組み付け,高圧のもとで約700℃までの高温を発生し、この装置をX線回折装置に取り付け,高温高圧X線その場観察実験が可能になった.また、このダイヤモンドアンビル高圧装置と顕微ラマン分光装置、赤外分光装置を組み合わせて、高圧下におけるラマン分光や赤外分光の測定を可能にした。 このシステムを用いて、氷天体の内部の流動性を議論するために、氷のVIの高圧下での粒成長速度が測定され,その圧力依存性を調を明らかにした。また、氷天体内部を構成する可能性のある物質を含む系であるFe-H2O系、また原始的な隕石中の有機物に類似したケロージェンの高温高圧下での相転移と反応関係を実験的に明らかにした。これらの実験の結果.35GPaの圧力で700C以上で金属鉄と水が反応して,FeOとFeHが生ずることが明かになった.また、この反応は5GPa以下の低圧では生じない。この反応は現在のプレート内部とともに,初期地球や始源的な小天体内部の温度圧力条件で生じることが明らかになった。この反応によって、氷天体のコアを作る金属鉄には水素が固溶している可能性があることが明らかになった。また、始源的隕石中の有機物のモデルとしてのケロージェンは常温で少なくとも9GPaまでは安定であり、1.5GPaで250℃で分解することが明らかになった。したがって、タイタンのような氷衛星内部ではKerogen様の有機物は安定に存在し得る。

    In this research, we clarified the phase transitions and partitioning of elements in mantle minerals in the transition zone and the lower mantle, i.e., stability of hydrous phases, melting and physical properties of magma, phase transition kinetics, core formation process in the early Earth. One of the important results in this study is on the stability of hydrous phases. We observed two new hydrous minerals which are expected to exist in the lower mantle ; i.e., phase G (Mg1.14Si1.73H2.81O6) and phase d-AlOOH.Phase G is stable at relatively low temperature around 1000-1200℃ at around 25 GPa and it is expected to exist in the peridotite layer in the cold slab descending into the lower mantle. Whereas phase delta AlOOH is stable in the sediment components in the descending slabs in the upper most part of the lower mantle. These phases work as the water carrier into the lower mantle. Another mportant results in this research is on decomposition kinetics of ringwoodite. We observed periclase and ilmenite, and priclase and stishovite as a metastable assemblage in the beginning of the decomposition of ringwoodite. These metastable assemblages eventually disappeared within 10 minutes to form stable assemblage, i.e., periclase and perovskite.

    We have developed the mulitanvil high pressure apparatus by which we can make in-situ optical sutudeies. This high pressure system is composed of 30ton uniaxial press, small guide block, outer anvils made of tungsten carbide, and inner anvils made of single crystalline diamond or single crystalline sapphire. In order to drive the diamond or sapphire multianvil, we adopted the DIA type cubic guide block system. The anvils in the guideblock are made of tungsten carbide and composed of two H anvils fixed in the upper and lower guide blocks, and four V anvils which are perpendicular to the H anvils. The anvil heads are made of single crystalline diamond or sapphire and serve as the window for the in situ optical measurements. Combining the present high pressure system and micro Raman spectrophotometer, we can make the Raman spectrum measurement at high pressure. Using this system we measured the Raman spectra of silicon and ruby at high pressure.
