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.

Suppe0073759已经研究了与印度 - 欧拉西亚碰撞相关的田谷肠内山脉，以了解负责这种造成的动态过程。 但是，时间和短期与长期变形率是有争议的，导致模型在过去的几百万年中，田山的变形可能已经显着加速。 这项研究的一个目的是通过提供来自生长层分析的新约束来测试这些模型，该分析对田山在不同时间尺度上的变形率进行了分析。 结果将适用于理解印度 - 欧拉西亚碰撞，并应促进此类碰撞的模型。
