中国晚古生代主要发生了2个重要地质事件:一是古中亚洋于晚泥盆—早石炭世俯冲消减,以及兴蒙造山系把古中国与西伯利亚陆块缝合成巨型古亚洲陆块;二是古特提斯扩张和古亚洲南东南边缘离散。在晚古生代—三叠纪期间,古亚洲克拉通发育了以下3类原型盆地:1)会聚边缘盆地,主要形成于中晚泥盆世—石炭纪北方陆块南缘,泥盆纪—石炭纪中央造山系的一侧或两侧,晚二叠世—三叠纪华南陆块南缘;2)离散边缘盆地,古特提斯拉张期形成,主要分布于华南陆块南缘、北西缘和塔里木南缘;3)克拉通内盆地,包括台内坳陷、台内断坳或断陷、裂谷和由残余海盆演化成的坳拉槽(钦防盆地)。

Two important geologic events took place in China during the Late Paleozoic: the Ancient Middle Asian Ocean underrode and consumed during the Late Devonian to Early Carboniferous, and the Xing-Meng orogenic belt combined the Ancient China and the Siberia Plates into the giant Ancient Asian Plate; the Palaeotethys expanded and the SES edge of ancient Asia detached. 3 types of prototype basin were generated in the Ancient Asian Craton from the Late Peleozoic to Triassic: 1)convergent edge basin, mainly in the southern edge of D(2+3)-C North Plate, one side or both sides of the D-C central orogenic belt, and the southern of P2-T South China Plate; 2)detached edge basin, distributed in the southern and northwestern edge of South China Plate and the southern edge of Tarim basin; 3)inner Craton basin, including inner platform depression, fault-depression or fault, rift and aulacogen from remaining basin.
