This proposal outlines a research plan to explore tectonic-geomorphic interactions in the Pamir region of far western China. In the region of the high peaks Kongur Shan (7719 m) and Muztagh Ata (7546 m), the correlation between areas of high relief and deep, rapid exhumation with areas of presumed rapid glacial and fluvial erosion suggests a positive feedback loop, in which rapid erosion causes thermal and mechanical weakening of the crust, flow of material toward the site of rapid glacial and fluvial erosion suggests a positive feedback loop, in which rapid erosion causes thermal and mechanical weakening of the crust, flow of material toward the site of rapid erosion, and deep exhumation. Exhumation of these peaks is also partly tectonic in origin, related to movement along the extensional Kongur detachment. The goal of this project is to understand the relative contributions of tectonic, erosion and climate to both the spatial and temporal exhumation pattern observed in the Kongur-Shan-Muztagh Ata region. For this, we will use a combination of thermochronologic work, thermal modeling, surface exposure dating, structural and geomorphic mapping, landscape analysis, digital elevation model interpretation, and satellite image interpretation.

该建议概述了中国西部帕米尔地区构造-地貌相互作用的研究计划。在Kongur Shan（7 719米）和Muztagh Ata（7 546米）高峰地区，高起伏和深而快速的剥露区与假定的快速冰川和河流侵蚀区之间的相关性表明存在一个正反馈循环，快速侵蚀造成地壳的热和机械弱化，物质流向快速冰川和河流侵蚀的地点表明存在一个正反馈循环，其中快速侵蚀导致地壳的热和机械弱化，物质流向快速侵蚀的地点，以及深度挖掘。这些山峰的折返也部分是构造成因，与沿着伸展的公古尔拆离带的运动有关。该项目的目标是了解构造、侵蚀和气候对在Kongur-Shan-Muztagh Ata地区观察到的空间和时间剥露模式的相对贡献。为此，我们将使用热年代学工作，热建模，表面暴露测年，结构和地貌测绘，景观分析，数字高程模型解释和卫星图像解释的组合。
