摘　　要：河北省沽源一带铀钼等多金属成矿地质条件优越,为了寻找铀钼等多金属矿,笔者在该区开展了1/5万水系沉积测量。依据测试样品分析结果和相关规范要求以及成矿地质条件,共圈定57个地球化学综合异常,其中甲类1个、乙类26个、丙类30个。在AS7甲类异常(大官厂)和2AS3乙2异常(新房)对应区域,发现铀、钼异常较好,在此基础开展了1/1万土壤测量进行查证,结果表明上述异常特征明显、具有一定规模等,对该区今后铀、钼等多金属地质找矿具有重要指示意义,并暗示该区具有寻找铀钼多金属矿的重大潜力。The geological conditions of the Uranium and molybdenum polymetallic deposits are superior.In order to find uranium molybdenum polymetallic ore,we carried out 1/50 000 stream deposition measurements and 1/10 000 soil measurement in the key prospecting area.According to the analysis results of samples analysis,the requirements of the relevant regulations and metallogenetic conditions,fifty-seven geochemical anomalies were delineated,including one anomaly of class A,twenty anomalies of class B and thirty anomalies of class C.Especially AS7 anomaly of class A in Da guanchang area and 2AS3 anomaly of class B in Xinfang area,which have an important significance in the area of geological prospecting uranium molybdenum polymetallic,also suggesting that this area has great potential for uranium molybdenum polymetallic deposit.
