The Main Mantle Thrust, located in the northwestern Himalaya of Pakistan, separates the Kohistan island-arc terrane on the north from the Indian plate to the south, and represents the westward continuation of the Indus Suture zone into the western Himalaya. The focus of this collaborative project (with Dartmouth College, EAR88-16929) is to examine metamorphism associated with the terrane boundary to establish pressure- temperature-time paths and radiometric dates of structural events. Data obtained using these techniques will be integrated to place important constraints on tectonic-thermal models for the Himalaya, and compressional mountain belt in general.

主要的地幔推力位于巴基斯坦西北部的喜马拉雅山脉，将北部的Kohistan Island-Arc Terrane从印度板块分开，代表了印度印度缝合区向西延续到西部喜马拉雅山脉。 该协作项目的重点（与达特茅斯学院（Dartmouth College），EAR88-16929）是检查与地层边界相关的变质，以建立结构事件的压力温度时间路径和辐射日期。 使用这些技术获得的数据将集成，以对喜马拉雅山的构造 - 热模型以及一般的压缩山带施加重要限制。
