摘要
以东海陆架盆地早第三纪裂谷区内若干盆地的重磁、构造、地层资料为基础,讨论了裂谷期成因地层控制因素。重新认识了基底对裂谷边界、构造格局、深切平移断裂的控制作用以及受断裂控制的裂谷地貌特征。以长江凹陷、瓯江凹陷为重点,对裂谷期裂谷盆地充填特征展开对比讨论。同时,从盆地结构、相对海平面变化和物源供给等方面探讨了裂谷盆地地层成因机制。
Based on the data of gravity-magnetic anomaly,tectonics and strata from rift terrain in Eogene in the shelf basin,East China Sea,this paper demonstrates the genetic factors for strata developed in rift periods, and discusses the controlling influence of basement for rift boundaries,structure pattern and deep-cutted strike-slip faults and rift geographical features controlled by faults. From the examples of Changjiang and Oujiang troughs, the mechanisms of genetic strata development from tectonics, relative sea level changes and sediment supply have also been analysed.
