New progress in the geoscience study of the Qinghai-Tibet Plateau

After four years of implementation of the project Geological Records and Mechanism of the U-plift of the Qinghai-Tibet Plateau the following progress has been made:it has been verified that there exist two kinds of basement and four phases of tectonic deformation in the West Kunlun;the degree of research on the Hoh Xil basin has been raised greatly and the history of the uplift of the western Yunnan Plateau has been reconstructed.;the temporal-spatial structure and crustal growth mode of the Gangdise tectono-magmatic belt have been determined;it has been further made clear that three subzones and four culmination phases of volcanic activity exist in the Cenozoic volcanic belt of the Qiangtang area;it has been ascertained that the Namjagbarwa structural node is a wedge structure composed of three tectonic u-nits,and the Namjagbarwa Group is Proterozoic in age;GPS monitoring of the rate of crustal movement in the northern part of the plateau shows two whirl structures;three types of the lithosphere of the plateau have been distinguished and three geochemical end-members recognized;a group of new data about the uplift of the plateau,basin sediments,geologic ages etc.have been obtained and some new views in respect to the influence of the plateau uplift on the climate proposed.
