REU: COLLABORATIVE RESEARCH: Metamorphic Evolution of the Nanga Parbat Massif: Metamorphism, Fluid Flow, and Granite Genesis

人们对流体在各种地壳过程中的重要性重新产生了兴趣，如花岗岩成因、变质作用以及热量和质量传输。该项目将利用巴基斯坦喜马拉雅地区非常年轻的Nanga Parbat-Haramosh地块来研究花岗岩岩浆作用、变质作用和流体流动之间的关系。这一地区记录了快速的抬升和剥蚀，看起来几乎是与花岗岩形成和可能的地形驱动的流体断裂一起出现的。这一假设将通过对南加帕尔巴特-哈拉莫什地区的岩石学、稳定同位素、年代学和构造的综合研究来验证。利用这些技术获得的数据有望对地表驱动流体在喜马拉雅西北和挤压山带花岗岩和变质岩成岩作用中的作用提供限制。

There is renewed interest in the importance of fluids in a variety of crustal processes such as granite genesis, metamorphism and heat and mass transport. This project will study relationships between granite magmatism, metamorphism and fluid flow using the very young Nanga Parbat-Haramosh Massif in the Pakistan Himalaya. This area records rapid uplift and denudation that appears near coevil with both granite formation and possible topographically driven fluid flaw. This hypothesis will be tested by an integrated petrologic, stable-isotopic, geochronologic and structural study of the Nanga Parbat-Haramosh area. Data obtained using these techniques are expected to provide constraints on the role of surface-driven fluids in the petrogenesis of granites and metamorphic rocks in the NW Himalaya and in compressional mountain belts in general.
