SEQUENCE STRATIGRAPHY AND SEDIMENTORY EVOLUTION OF THE MIDDLE JURASSIC IN NORTHERN CHAOSHUI BASIN

摘要: 在系统分析研究区地表露头、岩心、测井和地震资料的基础上,运用层序地层学理论和方法,针对陆相盆地层序地层分析的实际,将湖水盆地北部亚盆地中讲罗统龙凤山组划分为4个三级层序和2个二级层序.通过系统的沉积体系及沉积淀化分析,发现从一个三级层序到另一个三级层序,或物源区有很大变化,或沉积作用方式发生变化;物源区随时间的变化,反映了构造的控制作用.

Abstract: On the basis of systematic analysis of outcrops, well cores, log and seismic stratigraphy, the stratigraphic sequence of the Middle Jurassic in northern Chaoshui basin was divided into 4 third-order sequences and 2 second-order sequences. According to depositional system and sedimentary evolution analysis, it was indicated that the prevenance changed rapidly and the sedimentary style varied from one thirdorder sequence to another, The variation of prevenance with time reflected tectonic control.
