This project aims to study changes of deep Earth materials and high pressure materials under high pressures.(1) Laser ablation mass spectometry has been developed to analyze trace and light elements in small area.(2) Properties of elemental carbon and related diamond materials have been studied for its industrial utilization as the hard material.(3) Nature of lithospheric mantle beneath the archean mantle has been investigated by using mantle zenolith and kimberlite magma as a prove.(4) High pressure phase transition in silicate minerals has been studied to clarify relationships between seismicity of the subduction zone and their transformation process. These studies have been made as a cooperative research with State University of New York at Stony Brook.

本项目旨在研究地球深部物质和高压物质在高压下的变化。(1)激光烧蚀质谱法已发展成为一种在小区域内分析痕量和轻元素的方法。(2)为了使金刚石材料在工业上得到应用，对元素碳及其相关金刚石材料的性能进行了研究。(3)以地幔天顶岩和金伯利岩岩浆为证据，探讨了太古代地幔下岩石圈地幔的性质。(4)本文研究了硅酸盐矿物的高压相变，以阐明俯冲带地震活动与其相变过程之间的关系。这些研究是与位于斯托尼布鲁克的纽约州立大学合作进行的。
