Research Abstract

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
