G. Ernst, Stanford University, Stanford, CA, and approved January 25, 2008 (received for review June 14, 2007) The surface uplift history of the Tibetan Plateau and Himalaya is bounding the northern boundary of the Paleogene proto-Tibetan among the most interesting topics in geosciences because of its Plateau. The HXB, characterized by low-gradient fluvial and effect on regional and global climate during Cenozoic time, its lacustrine facies, may be an analogue of the Qaidam or Tarim basin influence on monsoon intensity, and its reflection of the dynamics systems on the northern margins of the modern high plateau, which of continental plateaus. Models of plateau growth vary
