| 摘 要： | 辽吉台块具有基底和盖层两个明显不同的发展演化阶段，在此着重讨论其盖层阶段的岩石建造及构造演化。将盖层岩系列分为五个岩石建造，并分析讨论各建造的沉积环境和古地理。试图通过建造来反映构造演化特征。认为，在建造组合特征上与周边相邻地质体相比具有独特性，并且具有两个大的构造演化阶段，岩相古地理及古地磁表明辽吉台块具有由赤道附近向北运移的演化过程，推测于晚二叠世末与周边地质体拼合。

| Abstract: | There are two obviously different evolutionary stages of basement and the cover om the Liaoji platform block.This paper describes emphatically rock formation and structure evolu-tion in the cover stage,The cover rock series were divided into 5 rock formations ,and thesedimentary environment and paleogeography are analysed and discussed as well as anallempt are made for reflecting structure evolutionary features through the formations,Thecharacteristics of formation and association are unique in comparison with neighbouring geo-logic body,indicating two large structure evolutionary stages. The lithofacies and paleogeog-raphy and paleomagnetism show that Liaoji platform block has an evolutionary process thatshifted towards N from the vicinity around the equater,and matched with the nearby geologicbodies in the end of the late Permian. |
