摘　　要：通过对柴达木盆地西北缘层间氧化带及其铀成矿条件的分析,认为本地区区域层间氧化带的尖灭与油气聚集带的背斜带及同生断裂紧密伴生,渗入型含氧水和渗出型油田水交界处的铀矿化是主要的铀矿化类型,侏罗系和第三系为主要的找矿目的层。The paper studied the interlayer oxidation zones and uranium mineralization in the northwest margin of Qaidam Basin, pointed out that the wedge-out of interlayer oxidation zones accompanied with syngenetic faults and anticlinal zones of oil-gas accumulation area in the study region where the primary uranium mineralization type occurred in the junction between penetration water with oxygen and exudation water of oil field, the key strata for uranium prospecting should be focused on Jurassic and Tertiary.
