摘　　要：安徽省东至县青草尖—戴村金多金属矿预查区及周边发育明显的水系沉积物地球化学测量异常,为查明区内元素地球化学特征,通过土壤、岩石等化探勘查工作,进一步缩小了异常范围。经异常检查及探槽验证,在查区发现了数条金矿化体。初步证实具有显著的浓集中心、强度强、规模大等特征的土壤异常主要由金矿化引起,岩石化探异常中心往往直接指示金矿化体的存在。Obvious anomaly of geochemical stream sediment survey is developed in the pre-survey are of gold polymetallic ore in the Qingcaojian-Daicun area in Dongzhi County,Anhui Province ore nearby.In order to find out the geochemical characteristics of elements in the survey area.It was carried out to further narrow the anomaly range through geochemical soil exploration or geochemical rock exploration.A number of new gold mineralization had been discovered in the survey area,after anomaly inspection and exploratory trench verification.It was initially confirmed that gold mineralization caused soil anomaly,which has obviously concentration center,strong intensity and dimension.The center of geochemical rock anomaly often directly indicate the existence of gold mineralization.
