摘　　要：通过对鄂尔多斯盆地镇原地区长8油层组砂岩碎屑骨架组分、岩屑组分、阴极发光及重矿物类型与特征研究,同时结合沉积构造及砂岩变化趋势等方面的资料,对物源区进行综合分析,结果表明,镇原地区长8油层组的主要物源来自东北、西南两个方向,并以西南部为主要物源区;源区母岩主要为火山岩及部分变质岩杂岩区,同时还有少量沉积岩。According to the research about skeleton sandstone detrital composition, debris composition, cathodoluminescence, heavy mineral types as well as the data of sandstone sedimentary structure and trend, the main source direction of Chan g-8 member in Zhenyuan area comes from the northeast, southwest, and the southwest is the main provenance. The main parent rocks are volcanic and part of metamorphic complex, as well as small amounts of sedimentary rocks.
