This research project is a cooperative study between University of Tsukuba and State university of New York at Stony Brook on the behavior of mantle materials, mainly silicate minerals, at high temperature and high pressure conditions using high pressure synthesis techniques, chemical composition analysis, especially for trace elements, SOR X-ray crystal structure analysis and other physical and chemical techniques. Following scientific problems were mainly studied : (1) the effects of hydrogen contents on the behavior of silicate minerals at high TP conditions (founding and analysis of new hydrous high pressure silicate mineral phases ; decreasing of melting points of mantle material with the variation of water contents, content of hydrogen in mantle minerals and the partitioning of H between minerals, etc.), (2) synthesis of diamond and related materials (growth of large single crystal diamond using two stage method, growth of cubic BN,diamond growth from SiC,etc.), (3) application o … More f high energy ion-beam on the trace element chemical analysis (development of PIXE,RBS,ERDA methods), (4) study of inclusion in diamond (trace elements analyzes of natural diamond inclusion, etc.), (5) ion-beam luminescence study of diamond and mantle materials (characterization of natural and synthetic diamonds using ion-luminescence) and (6) application of ultra short wave length X-ray on the characterization of materials (high precision crystal structure analysis of diamond using Wka X-ray).All of the results were discussed at a scientific symposium hold at Hilo-city, Hawaii, U.S.A.from December 8 to 13,1994. Participants of the symposium are 10 from University of Tsukuba side and 5 from SUNY at Stony Brook side which include two invited researchers from University of Tokyo and Geophysical Laboratory, Carnegie Institution. All of the discussions were fruitful and all of the participants recognized the importance of the cooperative study of two Universities and these type of cooperation project. Less

本研究项目是筑波大学与斯托尼布鲁克的纽约州立大学合作进行的，利用高压合成技术、化学成分分析，特别是微量元素分析、SOR X射线晶体结构分析和其他物理化学技术，对以硅酸盐矿物为主的地幔物质在高温高压条件下的行为进行研究。主要研究了以下科学问题：（1）高TP条件下氢含量对硅酸盐矿物行为的影响（新的含水高压硅酸盐矿物相的发现与分析，地幔物质熔点随水含量的变化而降低，地幔矿物中氢含量及氢在矿物间的分配等），(2)金刚石和相关材料的合成（使用两步法生长大单晶金刚石、生长立方BN、从SiC生长金刚石等），(3)应用O ...更多信息 （4）金刚石包裹体的研究（天然金刚石包裹体的微量元素分析等）; (5)金刚石和地幔物质离子束发光研究（6）超短波长X射线在材料表征中的应用（Wka X射线对金刚石晶体结构的高精度分析），这些结果已在1994年12月8日至13日在美国夏威夷希洛市举行的科学研讨会上讨论。参加研讨会的有筑波大学方面的10名和纽约州立大学斯托尼布鲁克方面的5名，其中包括东京大学和卡内基研究所地球物理实验室的两名特邀研究人员。所有的讨论都是富有成果的，所有的与会者都认识到两所大学合作研究和这种合作项目的重要性。少
