摘　　要：在河北北部蔡家营矿区上方开展了细粒级活动态土壤剖面及面积性地球化学勘查方法试验。结果表明,在埋深小于200 m的隐伏Pb-Zn矿体上方均有明显的活动态及细粒级地球化学异常,与已知矿体吻合程度较高;细粒级全量测量在矿区外围面积性试验同样可以指示隐伏多金属矿床,表明细粒级测量可以作为寻找该区隐伏铅锌多金属矿的有效手段。Fine particle total measurement and MOMEO were carried out in Caijiaying area located in the north of Hebei Province. The results show that anomalies delineated by two kinds of methods are quite in accordance with the deep concealed Pb,Zn orebodies with the distance less than 200 m. In the surrounding areas,the anomaly can be indicated effectively by fine particle total measurement.These results show that the fine particle measurement can be used to search for concealed polymetallic Pb-Zn deposits.

关 键 词：蔡家营 隐伏多金属矿 细粒级测量 金属活动态测量
