南黄海中部隆起中-古生界构造特征分析
|
摘要
位于南黄海盆地中部的南黄海中部隆起,沉积了较厚的海相中-古生界和陆相中-新生界地层,在生成及发展过程中经历了多期构造运动的叠加改造,构造特征复杂。针对该地区中-古生界地质属性、断裂发育及构造演化认识不清等问题,通过对地震资料的解释,结合区域钻井等资料,采用地质与地球物理相结合的方法对研究区中-古生界构造特征进行了分析。结果表明,中部隆起存在八个地震反射界面和五套地震层序,海相地层自上而下划分为上、中、下三大构造层,其中上构造层变形复杂,逆冲叠瓦状断裂发育,中、下构造层变形较弱,以宽缓的褶皱构造为主。中部隆起主要发育有逆冲断裂、正断裂和反转断裂,在平面上呈NE,NW和近EW向展布。最后综合中部隆起区域地质资料,探讨了研究区古生代以来的构造演化特征。
Located in the middle of the South Yellow Sea basin,middle uplift of the South Yellow Sea composed of thick Mesozoic-Palaeozoic marine strata and Mesozoic-Cenozoic continental strata,which has complicated tectonic features after overlying transformation by multiple-period tectogenesis in the generation and development period.In order to solve the ambiguity problems of geological attribute,fault development and tectonic evolution in Mesozoic-Palaeozoic,based on seismic data interpretation and regional drilling data,this paper made analysis of the tectonic characteristics of Mesozoic-Palaeozoic in this region by adopting the combined methods of geology and geophysics.The results showed that eight seismic reflection interfaces and five seismic sequences existed in the middle uplift.This paper classified Mesozoic-Palaeozoic marine strata into lower,middle and upper layers.The upper layer is complicated with extruded structure styles and well developed imbricate thrust faults.The middle and lower layers are characterized by simple deformation and gentle fold structure.Besides,thrust faults,normal faults and inverted faults are well developed in the middle uplift and stretch out in the directions of NE,NW or nearly EW in the plane.Finally,based on the geological data of the middle uplift,this paper discussed the characteristics of tectonic evolution since Palaeozoic in the research area.
