Research Abstract

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.
