摘要
晚二叠世至古近纪,在昆仑-秦岭山脉以北的中国北方可能存在过一个后海西地台。它原是晚古生代冈瓦纳与西伯利亚大陆碰撞后形成的一个复杂褶皱区。后经准平原化而成为接受中、新生代沉积盖层的年轻地台。与此同时,劳亚大陆东部也有数个后海西地台形成。俄罗斯中亚古生代褶皱区也遭受过长期剥蚀,曾一度经历过后海西地台的发展。这一事件在中国北方的许多沉积盆地也多有发现,在中国古地理图上也有显示。但是,中国后海西地台遭到了后继构造运动,特别是喜马拉雅运动的破坏。中国后海西地台的确认有助于重新审视中生代以来的中国地质历史和中、新生代沉积盆地的形成和演化,以及从不同视角重新思考对某些地质问题的认识。
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.
