摘要 通过对准噶尔盆地东部侏罗系的沉积环境和沉积相的研究,应用层序地层学方法对侏罗系进行了进一步划分与对比;应用地质、测井及地震等方法对该区的沉积相和沉积层序进行了综合分析.认为,本区侏罗系主要是一套受构造和气候条件控制的陆源碎屑沉积.按其沉积特征可分为潮湿型与干旱型两类;按低位体系域的特点又可分为北部缓坡型和南部陡坡型. According to sedimentary environment and facies, this paper further classified and correlated the Jurassic in eastern Junggar basin by using sequence stratigraphy method, and comprehensively analysed sedimentary facies and sequence of study area by applying geologic, logging and seismic methods. It is considered that Jurassic is a set of terrigeneous clastic sediments controlled by tectonic and climate conditions, which is divided into humid and arid type based on sedimentary characteristics; and also divided into northern gentle slope type and southern steep slope type based on low-water level system tract.
