The Mesozoic to Recent tectonic evolution of Asia is the result of the convergence and collision of fragments of Gondwana and Eurasia. Whereas it is widely accepted that the collision of India with Eurasia substantially thickened and uplifted the Tibetan plateau, there is considerable controversy about the amount and distribution of strain in eastern Tibet and Southeast-Asia. In the Himalayas, Pamirs, and Tibet a growing geochronologic database is placing constraints on the timing and duration of magmatic, metamorphic, deformation, and exhumation episodes. In contrast, there is very little comparable modern geo/thermochronology, petrology, and structural analysis for the areas south and southeast of the eastern Himalayan syntaxis. This project will initiate the acquisition of amodern geo/ thermochronologic data base by dating recently collected samples from east-west traverses across central and eastern Myanmar, the state that contains the eastern plate boundary of India and that has been nearly inaccessible over the last decades.

亚洲近代构造演变的中生代是冈瓦纳和欧亚大陆碎片的收敛和碰撞的结果。尽管人们普遍认为，印度与欧亚大陆的碰撞显着增强并提升了藏族高原，但关于西藏东部和东南亚的应变的数量和分布存在相当大的争议。在喜马拉雅山脉，帕米尔（Pamirs）和西藏（Pamirs）和西藏，一个日益增长的地球文学数据库正在对岩浆，变质，变形和发掘发作的时机和持续时间施加限制。相反，对于喜马拉雅东部语法的南部和东南部，几乎没有可比的现代地理/热量学，岩石学和结构分析。该项目将通过最近收集的缅甸中部和东部遍历的样品来开始收购Amodern Geo/热量数据基础，该州包含印度的东部板块边界，在过去的几十年中，这几乎是无法访问的。
