REEXAMINATION ON THE INTRACONTINENTAL-TYPE OROGENY

Zhao Zongpu(Institute of Geology, Chinese Academy of Sciences, Beijing 100029)  
The current New Global Tectonics is proved to be partly true and partly false. It has already brought about puzzles and difficulties in the study of Chins' s continental geology. Orogenis which occurred at all geological stages in China's continent belong to the intracontinental-type orogeny. So, dealing with the formation and tectonic evolution of the Qinghai-Tibet plateau by the suspected terrain doctrine, the continental collision theory and the Andean-type orogenic model has fallen in erroneous zones. The Qinling-Dabie orogenic belt is an intracontinental-type one, independent of continental collision. In this paper the crust-mantle detachment model as a causal mechanism of intracontinental orogeny is used to explain the formation of ultra -high pressure metamorphic rocks. Such rocks is considered to be the most effective indicator to identify a series of geological events due to lithosphere compression.
