9418702 Madden This project is part of a multidisciplinary study of the Nanga Parbat-Haramosh Massif of the northwestern Himalaya, Pakistan. The Principal Investigators wish to assess the recent and still-active processes responsible for an extraordinary episode of very young high-grade metamorphism, partial melting, high strain, and rapid denudation focused around the center of Nanga Parbat. Their ultimate goal is to exploit the excellent exposures and access to active tectonic processes offered by Nanga Parbat to understand the mesoscale interaction between petrological and mechanical processes during collisional orogenesis. To accomplish these goals they propose to integrate a wide variety of measurements made using techniques of geochronology, petrology, stable-isotope geochemistry, radiogenic tracer-isotope geochemistry, seismology, magnetotelluric sounding, structural geology, and geomorphology, and then place their results into a geodynamic context. ***

9418702马登这个项目是对巴基斯坦喜马拉雅西北部的南加帕尔巴特-哈拉莫什地块进行的多学科研究的一部分。首席调查人员希望评估最近和仍然活跃的过程，这些过程导致了以南加帕尔巴特为中心的非常年轻的高级变质作用、部分熔融、高应变和快速剥蚀。他们的最终目标是利用Nanga Parbat提供的极好的暴露和接触活动构造过程的机会，以了解碰撞造山过程中岩石学和力学过程之间的中尺度相互作用。为了实现这些目标，他们建议整合使用地质年代学、岩石学、稳定同位素地球化学、放射成因示踪同位素地球化学、地震学、大地电磁测深、构造地质学和地貌学等技术进行的各种测量，然后将其结果置于地球动力学背景下。***
