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 Lehigh University, EAR88-16887) 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.

主地幔逆冲断层位于巴基斯坦喜马拉雅山西北部，将北部的科希斯坦岛弧地体与南部的印度板块分开，代表印度河缝合带向西延续到喜马拉雅山西部。 该合作项目（与理海大学，EAR88-16887）的重点是检查与地体边界相关的变质作用，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被整合，以对喜马拉雅山和整个挤压山带的构造热模型施加重要约束。
