Abstract

Abstract

The Qinghai-Tibet plateau, the best field laboratory for continental dynamics, involves many scientific problems in the frontiers and hotspots of modern earth sciences. Up to now, a lot of models including plate tectonics cannot rationally explain key geological and geophysical phenomena related formation and evolution of the plateau. According to a new idea involving coupling between the lower crust and upper crust, orogens and basins, this paper approaches the lower crust laminar tectonic model for uplifting mechanism of Qinghai-Tibet plateau by tectonic analysis of different scales, levels and blocks, multistage evolution. The crustal thicking and tectonic uplift of Qinghai-Tibet plateau result from the thermal softening rocks in the lower crust flow from the Himalayan foreland basin, Tarim basin and Sichuan basin to the plateau during Late Cenozoic era.
