40 Ar/39 Ar Geochronological Research in the Sambagawa and Adjacent Terranes, Japan: Analytical Expenses

基金将支付所涉分析实验室费用 在经典的40 Ar/39 Ar年代学研究项目中， 桑巴川高压变质带及邻近岩石构造单元 在日本的四国岛和本州岛暴露出来。 旅行和 项目的所有后勤费用由赠款支付 授予R.D. Dallmeyer来自美国国家科学院 基金会（12,154美元：INT-8815932）和A。高州（岛根 日本科学促进会（Japan Society for the Promotion of Science）。 日本的合作伙伴（A。Taksu和T.平岛） 一直在研究桑巴川的热演化 和邻近的带超过10年。 美国合作者 （R.D. Dallmeyer）一直在利用40 Ar/39 Ar定年方法 在主要造山带的复杂多变质岩中。 的 拟议研究的具体目标是校准 桑巴川的时间-温度-压力演化史 并协调结果， 提出的各种构造模式。 预期结果将是 不仅对日本的重要性，但高- 压力俯冲复合体在世界各地的所有年龄。

Funds will defray the analytical laboratory costs involved in a 40Ar/39Ar geochronological research program in the classic Sambagawa high-pressure terrane and adjacent lithotectonic units exposed on the islands of Shikoku and Honshu, Japan. Travel and all logistical expenses of the project are covered by grants awarded to R.D. Dallmeyer from the U.S. National Science Foundation ($12,154: INT-8815932) and to A. Takasu (Shimane University) from the Japan Society for the Promotion of Science. The proposed Japanese collaborators (A. Taksu and T. Hirajima) have been investigating the thermal evolution of the Sambagawa and adjacent belts for over 10 years. The U.S. collaborator (R.D. Dallmeyer) has been utilizing the 40Ar/39Ar dating method in complex polymetamorphic terranes in major orogenic belts. The specific goals of the proposed research are to calibrate the time-temperature-pressure evolutionary histories of the Sambagawa terrane and adjacent areas and to coordinate the results with various proposed tectonic modes. The expected results will be of importance not only to the Japanese archipelago, but to high- pressure subduction complexes of all ages throughout the world.
