摘　　要：地球化学测量基本可查明工作区内金及多金属异常分布特征,发现新的矿化地段和异常区带,圈出地球化学异常,为勘区找矿提供物探工作和地表工程布置依据。对地球化学异常检查是最为快捷、有效的地质找矿方法。根据地球化学异常寻找盲矿体,在曹家沟金矿区是行之有效的方法,并取得了显著的效果。Geochemical survey can basically identify the abnormal distribution characteristics of gold and polymetal in the working area,find new mineralized areas and abnormal zones,ring out geochemical anomalies,and provide the basis for geophysical exploration and surface engineering layout.The detection of geochemical anomaly is the fastest and most effective method for geological prospecting.It is an effective method in Caojiagou gold mining area to search for blind ore body according to geochemical anomaly,and remarkable results have been achieved.
