摘　　要：沽源盆地位于华北地台北缘,是一个铀钼资源丰富的地区,目前已发现460、大官厂、秦家营等与中生代岩浆活动有关的铀钼矿床(点)。文章应用ETM图像对该区构造进行了解译研究,厘定了14条规模较大的区域性主干断裂,总结了该区构造格架,依据地质背景划分了3个断块。提出460、秦家营、大官厂、脑包山、三间房等矿床(点)具有北东向等距离分布的特点,并认为它们构成一个铀(钼)矿田。结合已有地质矿产资料初步归纳了6条区域找矿预测标志,圈定了4个铀钼矿找矿远景区。The Guyuan basin,located in the northern margin of the North China platform,is enriched with the uranium-molybdenum resources.At present,several deposits such as No.460,Daguanchang and Qinjiaying uranium-molybdenum deposit,have been discovered,which are related with Mesozoic magmatic activity.This paper introduced the structural features based on the interpretation of remote sensing image ETM in the region,and totally 14 regional larger scale faults were delineated,the tectonic framework is summarized,and the study area is divided into three fault-blocks based on the geological background.The uranium-molybdenum deposits （occurrences） of No.460,Qinjiaying,Da guangchang,Naobaoshan and Sanjianfang have equidistant distribution characteristics along NE-trending fault,and they constitute a uranium-molybdenum orefield.On the basis of known geological information and mineral deposit data,six regional prospecting criteria were summarized,and four uranium-molybdenum prospecting targets were outlined.
