Collaborative Research: Geodynamics of Intracontinental Mountain Building in the Tien Shan, Central Asia

9614119 Pavlis该项目涉及对世界上最大和最活跃的陆内山脉天山的深部结构和变形运动学进行多学科调查。 目的是了解陆内造山运动的动力学过程，将天山作为实验室，问：为什么以及如何在大陆区域内发生这种变形，这种变形如何随时间演化，深部结构对地幔流动的限制，这种可能的流动和先前存在的地质不均匀性与观测到的上地壳变形有何关系？该项目涉及地球科学的6个独立学科，美国的8个机构和来自6个国家（中国，法国，哈萨克斯坦，吉尔吉斯斯坦，俄罗斯和美国）的科学家。

9614119Pavlis This project involves a multidisciplinary investigation of the deep structure and kinematics of deformation of the Tien Shan, the largest and most active intracontinental mountain range in the world. The objective is to understand the dynamic processes responsible for intracontinental mountain building, using the Tien Shan as a laboratory to ask: why and how such deformation occurs where it does within continental regions, how such deformation evolves with time, what bounds does the deep structure place on flow in the mantle, and how do such possible flow and pre-existing geological heterogeneity relate to the observed deformation of the upper crust? The project involves 6 separate discipilnes of earth sciences, 8 institutions in the USA and involvement of scientists from 6 nations (China, France, Kazakhstan, Kyrgyzstan, Russia, and the USA).***
