摘　　要：苏里格地区石盒子组是鄂尔多斯盆地重要的油气勘探层之一,受西北和东北两大物源的控制。为重塑盆地的古地貌特征,再现古河流体系,以区域沉积背景为依据,结合砂岩的碎屑组分类型与重矿物分布特征,应用石英阴极发光分析技术对苏里格地区下石盒子组8段物源问题进行探讨。结果表明,苏里格地区物源方向主要为EN向和WN向。Shihezi Formation in Sulige Area was one of the important layers of oil and gas exploration in Ordos Basin,it was controlled by the northwestern and northeastern major provenances.In order to better reshape the ancient geomorphological features of the basin,reproduce ancient river system,based on regional depositional setting and in combination with the types of sandstone debris component,distribution characteristics of heavy mineral,quartz cathodoluminescence analysis techniques,the provenance of the 8th member in Shihezi Formation is studied,the result shows that the provenance there is from northeast and northwest.
