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--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。

Abstract: According to sedimentary environment and facies, this paper further classified and correlated the Jurassic in eastern Junggar basin by using sequence stratigraphy method, and compreben-sively analysed sedimentary facies and sequence of study area by applying geologic, logging and seismic methods. It is considered that Jurassic is a set of termigeneous 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 genue slope type and southem steep slope type based on low- wter level system tract .
