摘　　要：焉耆盆地南部凹陷是盆地博湖坳陷区南部的一个二级构造单元,具有一定的资源潜力和勘探前景,侏罗系是主要勘探目的层系。通过对该区重矿物、含砾粗碎屑组分、矿物成熟度及泥岩粘土成分等的分析,认为该区侏罗系存在两个主要的物源方向,一个来自南部库鲁克山,另一个来自西部的塔什店地区。The southern sag in Yanqi basin, a secondary structural unit in the southern part of Bohu depression, has certain exploration potentials, with Jurassic as its major exploration target. Based on analysis of heavy minerals, detrital components of gravel - bearing coarse fragments, maturity of minerals and clay components of mudstones, it is believed that Jurassic would have sourced mainly from two directions, which are the southern Kuluke Mountain and the western Tashidian area respectively.
