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? ***

9614970 Burchfiel 该项目涉及对青藏高原东缘进行为期四年的多学科研究，将整合空间大地测量 (GPS) 测量、现场地质和地貌研究、地形和等静压分析以及地球动力学建模。 目标是提高对青藏高原发展过程的认识，更广泛地说，是对分布式大陆变形过程的认识。 该研究以目前主要研究者在高原东缘的工作成果为基础，新的重点是高原的形态发展。 从广义上讲，他们寻求诸如以下基本问题的答案：西藏东部及其前陆的活跃应变（速度）场是什么？ 什么时候发展起来的？ 东部高原应变和变形的先验分布是怎样的？ 目前西藏东部的地貌是如何以及何时形成的？ 与当前的高原形态相比，主动应变的分布如何？ ***
