The Recent Structural, Morphologic and Dynamic Evolution of the Eastern Tibetan Plateau: A Multi-Disciplinary Study of Processes in Continental Deformation

9614970 Burchfiel该项目涉及一项为期四年的青藏高原东缘多学科研究，将整合空间大地测量、野外地质和地貌研究、地形和均衡分析以及地球动力学建模。其目的是增进对青藏高原发展过程的理解，更广泛地说，是对分布大陆变形的过程的理解。这项研究建立在目前首席调查员在高原东缘的工作成果的基础上，新的重点是高原的形态发展。最广泛地说，他们寻求这样的基本问题的答案：西藏东部及其前陆内的活动应变(速度)场是什么？它是什么时候发展起来的？沿东部高原的应变和变形的先期分布是什么？西藏东部目前的地貌是如何以及何时发展起来的？活动应变的分布与当前的平台形态相比如何？*

9614970 Burchfiel This project involves a four-year multi-disciplinary study of the eastern margin of the Tibetan plateau that will integrate space geodetic (GPS) measurements, field geologic and geomorphic studies, topographic and isostatic analyses, and geodynamic modeling. The goal is to improve understanding of the processes responsible for the development of the Tibetan plateau and, more generally, the processes responsible for distributed continental deformation. The study builds on the results of the current principal investigator's work along the eastern margin of the plateau, with a new focus on the morphological development of the plateau. In broadest terms, they seek answers to such fundamental questions as: What is the active strain (velocity) field within eastern Tibet and its foreland? When did it develop? What was the prior distribution of strain and deformation along the eastern plateau? How and when did the current morphology of eastern Tibet develop? How does the distribution of active strain compare to current plateau morphology? ***
