In this paper, based on the systematic collection, analysis and research of the existing data achieved in Himalayas, Lhasa and Qiangtang terranes, the authors conducted the balanced cross-section study. In the north Qiangtang, the line-balanced cross-section study shows that the Jurassic strata shortened by 25.18%, and the result in south Qiangtang is 33.57%. The balanced cross-section in Lhasa terrane is divided into two sections by central volcanic rocks. The study shows that the Late Cretaceous stratum of the south section is shortened by 20.68%, while 25.3% for the north section.
