Suppe0073759The Tian Shan intracontinental mountain range related to the Indian-Eurasian collision has been studied to understand the dynamic processes responsible for this type of orogenesis. However, the timing and short-term versus long-term rates of deformation are controversial, leading to models in which deformation in Tian Shan may have accelerated significantly in the last few millions of years. A goal of this study is to test these models by providing new constraints derived from growth strata analysis on the rate of deformation in Tian Shan over different timescales. Results will be applicable to understanding the Indian-Eurasian collision and should contribute to models of such collisions generally.

本文对与印度-欧亚大陆碰撞有关的天山陆内山脉进行了研究，以了解这种造山作用的动力学过程。 然而，变形的时间和短期与长期的速率是有争议的，导致模型中天山的变形可能在过去几百万年中显着加速。 本研究的一个目标是测试这些模型，通过提供新的约束来自生长地层分析的变形速率在天山在不同的时间尺度。 结果将适用于了解印度-欧亚大陆碰撞，并应有助于这种碰撞的模型一般。
