| 摘 要： | 华北地台东部石炭—二叠纪沉积建造由５个沉积层序构成，下部ＤＳ１—ＤＳ３为陆表海型层序，ＤＳ４为过渡型层序，ＤＳ５为湖泊型层序。从早石炭世晚期至晚二叠世早期，华北陆表海的海侵范围自东向西、自北而南依次发展，这一岩相古地理演化过程主要受地台北部的阴山—燕山造山带在华力西期已经开始关闭，而地台南侧的秦岭造山带在晚华力西期至印支期由东向西逐次闭合这一过程的控制。

| Abstract: | Carboniferous Permian sedimentary formations in the eastern part of the North China Platform comprise five depositional sequences.DS 1 to DS 3 in the lower part are marked by epicontinental depositional sequences,DS 4 is a transitional sequence,and DS 5 is a lacustrine sequence.From the late Early Carboniferous to early Late Permian,the extent of transgression of the North China epicontinental sea extended from east to west and from north to south.The process of this lithofacies paleogeographic evolution was mainly controlled by the closure of the Yinshan Yanshan orogen north of the platform in the Variscan period and west directed successive closing of the Qinling orogen south of the platform from the late Variscan to Indosinian periods. |
