NSF-CGP Fellowship: Ultrahigh-Pressure Metamorphic Rocks and the Geodynamics of Continental Collision-Subduction

9820171刘本提案支持斯坦福大学地质与环境科学系的Juhn G.Liou博士、东京工业大学地球与行星科学系的Shige Maruyama博士和日本早稻田大学地球科学研究所的小川洋士博士之间的美日合作。Liou博士将在TIT获得为期五个月的休假支持，以继续与丸山茂教授和小川喜树教授开展的名为“超高压变质岩与地球动力学碰撞-俯冲”的美日合作项目。刘博士在东京工业大学期间的主要研究目标是：(1)收集来自中国和哈萨克斯坦的石榴石橄榄岩数据；(2)哈萨克斯坦北部Kokchetav地块的岩石构造研究；(3)蓝片岩和榴辉岩研究丛书。刘博士在日本休假期间的主要具体任务包括：(1)完成1998年12月斯坦福国际超高压研讨会产生的几期特刊的编辑工作。其中一篇是关于《Kokchetav地块的岩石成因和构造》，将发表在日本地质学会的官方期刊《岛弧》上。(2)与丸山教授共同完成一本关于蓝片派和生态派的书，该书将由克鲁沃学术出版社出版。这本书将包含有关矿物学、岩石学、年龄数据和世界上所有蓝晶岩和榴辉岩地区的构造解释的信息。(3)利用日本英才中心的设施收集中国和哈萨克斯坦的石榴石橄榄岩的岩石化学数据，以评估与大陆碰撞和俯冲有关的上地幔的性质；(4)参与与中国大陆科学钻探项目有关的科学规划和研究，并与日方同事一起研究现有的岩心和地表样品；(5)与丸山教授和奥斯加瓦拉教授共同完成Kokchetav地块岩石构造演化的研究卷，因为通过美日课题组收集了许多全面的岩石化学数据；(6)协助督导两位教授的学生及助理研究员。为了鼓励学生积极参与国际会议(例如，2000年的国际地质大会和2001年在日本举行的国际榴辉岩会议)，丸山和小川方明为他们收集数据和准备手稿，并在日本各大学举办讲座和研讨会；以及(7)鼓励日本学生积极参与国际会议。预计这些研究人员之间的合作将促进进一步的合作。

9820171LiouThis proposal supports U.S.-Japan collaboration between Dr. Juhn G. Liou of the Department of Geological and Environmental Science at the Stanford University and Dr. Shige Maruyama, Department of Earth & Planetary Sciences, Tokyo Institute of Technology (TIT), and Dr. Yoshi Ogasawara, Institute of Earth Science, Waseda University, Japan. Dr. Liou will be supported for a five months sabbatical stay at TIT in order to continue a well established U.S.-Japan cooperative Project entitled "Ultrahigh-Pressure Metamorphic Rocks and the Geodynamics Collision-subduction" with Professors Shige Maruyama and Yoshi Ogasawara. Major research goals during Dr. Liou's stay in Tokyo Institute of Technology are: (1) data collection on garnet peridotites from both China and Kazakhstan; (2) petrotectonic research on the Kokchetav Massif, northern Kazkhstan; and (3) Research Book on Blueschists and Eclogites. Major specific tasks during Dr. Liou's sabbatical stay in Japan include the followings:(1) To complete editing several special issues resulted from the International UHP Workshop at Stanford in December 1998. One of them is on "Petrogenesis and Tectonics of the Kokchetav Massif" to be published in the Island Arc, the Official Journal of the Geological Society of Japan. (2) To complete a book on Blueschists and Eclogites with Professor Maruyama to be published by Kluwer Academic Press. This book will contain information with regard to mineralogy, petrology, age data and tectonic interpretation of all bluechist and eclogite localities in the world. (3) To collect petrochemical data on garnet peridotites from both China and Kazkhstan using the facilities of the /center of Excellence in Japan in order to evaluate the nature of the upper mantle associated with continental collision and subduction; (4) To be involved in scientific planning and research related to the Chinese Continental Scientific Drilling project, and to work on available core and surface samples with the Japanese colleagues; (5) To complete a research volume with professor Maruyama and Osgaswara on Petrotectonic Evolution of the Kokchetav Massif as many comprehensive petrochemical data have been collected through the U.S.-Japan study group; (6) To help supervise students and research associates of both Profs. Maruyama and Ogasawara for their data collection and manuscript preparation, and to give lectures and seminars in various Japanese universities; and (7) To encourage Japanese students to become actively involved in international meetings (e.g., the International Geologic Congress in 2000, and the International Eclogite Conference in Japan in 2001). It is expected that the cooperation between these researchers should foster further collaborations.
