Abstract:

A post-Hercynian platform might exist in North China to the north of Kunlun-Qinling Mountains from Late Permian to Paleogene. It was exactly a complex folded region that had been formed as a result of the collision of Gondwana and Siberia Continent in Late Paleozoic. After peneplanation, it evolved into a young platform receiving Meso-Cenozoic deposits. Meanwhile, several post-Hercynian platforms also developed in eastern Laurasia. The Paleozoic folded region in Russian Central Asia had also experienced a long period of denudation and once been a post-Hercynian platform. Such event has also been discovered in many sedimentary basins in northern China, and has been shown in the paleogeographic map of China. However, the post-Hercynian platforms in China have been destroyed by succeeding tectonic movements, especially the Himalayan movement. Confirmation of the existence of post-Hercynian platform in China will contribute to the review of geological history in China since Mesozoic and the formation and evolution of Meso-Cenozoic sedimentary basins, as well as the reconsideration of the understandings of some geological problems from different angles of view.

Key words: post-Hercynian platform in China, regenerated craton, geological history in China, paleogeography in China, Meso-Cenozoic sedimentary basin
