9725599 Yin The Altyn Tagh fault in northern Tibet has unique characteristics that make establishing its kinematic history pivotal to understanding the evolution of the Indo-Asian collision. This feature, arguably the largest active intracontinental strike-slip fault system on Earth, is a focal point in both end-member models that have been proposed to describe the mechanical behavior of continental deformation: distributed shortening and lateral extrusion. This project involves a four year, integrated geological, geochronological and geophysical investigation that will focus on the determination of the magnitude, rate, and distribution of slip on the Altyn Tagh fault at time scales between 10,000,000 years to 4 years. The principal investigators will utilize geologic mapping and geochronology to establish piercing points, use paleomagnetic analysis to investigate several possible oroclinal folds along the fault, undertake a GPS survey to establish the slip rate, slip distribution and locking depth along the fault zone, and use mapping and cosmogenic dating of geomorphological features to establish Quaternary slip rates. ***

9725599 Yin北西藏的Altyn Tagh断层具有独特的特征，使其建立了其运动学历史关键以了解印度亚洲碰撞的演变。 可以说，这一特征是地球上最大的活动肠内滑移断层系统，是两个末端模型中的一个焦点，旨在描述大陆变形的机械行为：分布式缩短和横向挤出。 该项目涉及为期四年的地质，地质学和地球物理研究，该研究将重点介绍在10，000，000年至4年之间的Altyn Tagh断层上的幅度，速率和分布。 首席研究人员将利用地质图和地质学来建立穿孔点，使用古磁分析研究沿断层的几个可能的口语褶皱，进行GPS调查，以建立滑动速率，滑动分布和沿断层区域的锁定深度，并使用地图和地球学特征的映射和宇宙学标准来​​建立播放速率。 ***
