Some bodies in the solar system have a magnetic field like the earth, and another bodies once had. The magnetic field of an Earth-like rock body originates from a dynamo driven by thermo-compositional convection of the liquid core. The lifetime of the magnetic field depends on how the compositional convection of the liquid Fe-alloy caused by the cooling of the core works. We have clarified how the compositional convection pattern of the Fe-FeS core changes depending on the chemical composition and pressure. It was found that relatively small bodies such as the Earth’s moon solidify mainly from the top of the liquid core, resulting in compositional convection.

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.

At the early history of the solar system, molten iron alloy is separated from silicate mantle to form an iron core at the center of the protoplanets. We investigated this process by using high-pressure and high-temperature experiments combined with synchrotron X-ray micro computed tomography. We found that a permeable flow of liquid iron alloy through the crystalline silicate grain boundary is a dominant core-mantle separation process in the protpplanets with which the radius is smaller than several hundred km.

In order to clarify the effects of light elements on density and elastic wave velocity of liquid Fe-alloy and to constrain the terrestrial core compositions, we have developed simultaneous measurement system of density and sound velocity for liquid materials under pressure. Density and elastic wave velocity were obtained simultaneously for liquid Ni-S and it is found that there is a linear relationship between these two physical properties. We also obtained following results; density and sound velocity of liquid Fe-Ni-C, effect of pressure on density of Fe-C and on sound velocity of Fe-Ni-C. These results provide important aspects for understanding the effect of light elements on the elastic properties of liquid Fe.

X線マイクロトモグラフィを使った高温高圧下における3次元イメージングからは試料の形状,体積,界面などの情報が非破壊で得られるため,高圧力科学の分野の応用性を広める技術である。我々はその地球科学的な応用研究をアメリカ合衆国の放射光施設Advanced Photon Source(APS)で行った(平成18〜19年度)。本研究では,そのときの経験をもとにX線マイクロトモグラフィ用に新しい高圧装置を開発した。平成19年度に作製した高圧装置はSPring-8のイメージング用ビームラインで使用することを念頭に設計され,総重量30kg最大荷重80トンの小型のものである。平成20年度はこの小型高圧装置の性能評価を兼ねてX線マイクロトモグラフィ実験をSPring-8のBL20B2で行った。再構築したCTイメージには高圧装置のフレームに起因する影が認められるが,形状は柱のない場合と解像度の範囲内では一致した。圧力4GPa温度1000Kまでの実験でも十分に可視領域が確保され内部のCT像を得ることが可能であった。このように所定の性能を発揮することを確認した。APSにおけるX線マイクとトモグラフィと比較すると,高圧装置の加圧能力は約2倍,データ収集時間は1/10以下,解像度は2倍程度,我々の方が優れていた。SPring-8とAPSではビームラインのスペックの差もあるが非常に満足の出来る結果であった。高圧装置は高輝度光科学研究センターに寄付されており,共同利用が可能である。

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.

In this fiscal year, I was concentrated on crystallographic orientation measurement and shaping of micro crystal (~500μm or less) of high pressure phases. I introduced a CCD camera to determine X ray position against the small specimen. This system works well even for other projects. Then, I examined appropriate way to shape small specimen, such as treating a grain in water to prevent the specimen flown away.
I am preparing a sphere specimen of hydrous β spinal with 3wt% water. This crystal was synthesized by Dr. Anton in this institute, and the water content was determined by Dr. Shinoda at Osaka City University by using FTIR method. The crystal structure of hydrous β spinal is monoclinic. Thus to avoid numerical analysis difficulty, I am considering to make a sphere for the final shape of the specimen by applying the air-round method frequently used in crystallography. This project will be the first example of resonant ultrasound spectroscopy to measure single crystal elasticity of high pressure phases.
Furthermore, we made important progress on data analysis of resonant peaks. With utilizing the specialty of lock-in amplifier detecting signal phase shift against reference input, we tried to peak fitting simultaneously on real and imaginary parts. We confirmed the resolution ability of the new algorithm by examining our own data at around 20-30 MHz successfully. We submitted the result, combined with the hardware progress of high frequency resonant ultrasonic spectroscopy, to Review of Scientific Instruments. -

We measured electrical conductivity of granulite from Hidaka metramorphic belt, Hokkaido, Japan. From the experimental results, we estimated the temperature of the high resistance region at depth of 10-30 km to be 600℃.
We conducted experiments to estimate connectivity of iron-iron sulfide melts in dunite and lherzolite matrixes by means of electrical conductivity measurement. From this series of experiments, we found that iron-iron sulfide melt connects if its volume proportion is more than 5 %. Therefore, segregation of core material from mantle should have easily occurred in the early history of the Earth.
We measured electrical conductivity of (Mg_<0.93>Fe_<0.07>)SiO_3 ilmenite at pressures of 25, 35 and 40 GPa and temperature of 500 to 1000 K. We found the pre-exponential term is constant of 3×10 S/m at all of these pressures. The activation energy at 0 GPa and activation volume are 0.69±0.04 eV and -0.90±0.10 cm^3/mol. Thus pressure dependence of ilmenite is quite large.
We also measured electrical conductivity of (Mg_<0.93>Fe_<0.07>)SiO_3 perovskite at pressures of 35 and 40 GPa and temperature of 500 to 1100 K. We found the pre-exponential term is constant of 1×10 S/m at both of these pressures. The activation energy at 0 GPa and activation volume are 0.39±0.02 eV and -0.06±0.04 cm^3/mol. Thus pressure dependence of pervoskite is one order of magnitude smaller than that of ilmenite. -

We have developed the high-pressure X-ray absorption technique to measure density of silicate melts at high-pressure using synchrotron X-ray and a multi-anvil apparatus, in order to determine partial molar volume of siderophile oxide liquid at high pressure. Density (ρ) is evaluated from X-ray absorption profile of a sample using the equation of I=I_0 exp(-ρμt), where land are intensities of transmitted and incident X-rays, respectively, μ is mass absorption coefficient of sample, and t is sample thickness. In this study, we used a single crystalline diamond cylinder as a sample capsule, because its low X-ray absorption, hardness, and inertness with silicate melts. Diamond capsule makes the densiy measurement of silciate metls under pressure possible.
High-pressure X-ray absorption experiments were conducted by using a DIA-type cubic anvil apparatus and a highly brilliant monochromatic X-ray at BL22XU of SPring-8,Japan. We used glasses with the compositions both of the MORB and of the Fe-bearing sodium disilicate for starting materials. Although densities of glasses, crystalline solids, and melts were determined up to 5 GPa and 1873 K, we have not determined the partial molar volume of liquid. This method can, however, yield a series of density data at high pressures and temperatures within an error of 1% enough to evaluate the partial molar volume of silicate liquid. -

地球中心核には鉄ニッケル合金の他に酸素・硫黄などの軽元素が約10重量%含まれていると考えられている。鉄一軽元素系融体の密度・粘性・電気伝導度などの物性は、核のダイナミクスや地球形成初期の核マントル分離過程などを明らかにする上で必要不可欠な情報である。これらの物性は温度圧力の関数であるとともに、化学結合性・結晶構造と密接な関連がある。このように鉄一軽元素系融体の構造の研究は物性研究の基本となる。本研究では放射光を用いた高温高圧X線回折実験から高圧下におけるFe-FeS系融体の静的構造を調べ、融体の構造と圧力・組成の関係を明らかにすることを目指している。
X線回折実験は高エネルギー加速器研究機構・物質構造科学研究所(PF)に設置された高圧X線回折装置MAX90を用いてエネルギー分散法で行った。昨年度FeS融体の構造の圧力変化に関する研究を行い、5GPaまでの圧力下でFeS融体の構造に大きな変化が見られないことを報告した。今年度はFe-FeS2成分系において、融体の構造と組成の関係について研究を進めた。圧力を3GPaに固定し、Fe-FeS系の共融組成を挟んで、Fe側とFeS側の数点の組成の融体に対するX線回折実験を行った。実験データから動径分布関数を求め、融体の近接構造に関する情報を導いた。その結果、Fe-FeS系の融体では共融組成の両側で大きく構造が変化することが確認された。すなわち、共融組成よりFe側ではS濃度の増加にともない第1近接のFe原子の数が減少していくものの純鉄に類似した構造を保持しているのに対し、共融組成よりFeS側では第1近接原子は異種原子であり、ほとんどFeSと同様の構造をとっている。このように、放射光を用いた高圧X線回折法による融体構造の研究は極めて有効であり、鉄一軽元素系の融体物性研究の有力な手段である。 -
球共振法によるメジャーライト焼結体の高温弾性率の研究

鉱物の高温弾性を研究する上で、球共振法は有効な方法である。数ミリサイズの大きな単結晶を得ることが不可能な高圧相鉱物に対しては、多結晶焼結体を利用することが考えられる。共振法で多結晶体を利用する場合は弾性的等方体として取り扱うので、試料の等方性が重要となる。また、空隙が存在すると正しく弾性率を評価できないので、空隙のほとんどない試料を準備する必要がある。本研究では、異方性の比較的小さい立方晶系のパイロープを選び、その多結晶体の高温高圧焼結を試みた。パイロープは上部マントルを構成する主要鉱物のひとつであるメジャーライトガ-ネットの端成分のひとつであり、その弾性率の研究は地球科学的にも重要な意味を持つ。高圧実験は岡山大学固体地球研究センターの1000トンプレスを用いた6-8式の2段加圧法で行った。出発試料にはパイロープ組成のガラスを用い、それを白金カプセルに封入し NaCl 圧力媒体中に置いた。焼結は9GPa、1400℃で60分以上保持することで行った。この条件では NaCl は軟化しており、試料にかかる応力は静水圧に近いと考えられる。静水圧下で合成することにより、多結晶試料に異方性が生じることを防ぐことができる。また、減圧時の差応力によって焼結体が割れないように、600℃の高温のまま減圧した。この方法で、理論値とほぼ等しい密度を持つ、空隙のないパイロープの多結晶焼結体を得た。この焼結体の弾性率を球共振法で測定し、体積弾性率と剛性率を決定した。その結果は、単結晶のパイロープに対して報告されている弾性率とほぼ一致し、多結晶焼結体が弾性的等方体であること示している。現在、高温で球共振法による測定を行っているが、150℃までは観測共振周波数に異常が見つかっておらず、高温での弾性率測定が可能であると考えられる。
