摘　　要：为了在闽西南坳陷带寻找深部盲矿体,在福建省黄田矿区开展了地球电化学勘查法找矿研究工作。结合该地区地质背景特征,利用衬度值异常和衬度累加值异常等地质统计方法,对典型的中、高温成矿元素地球电化学数据进行处理。结果表明,在已知矿体上方出现明显的地电提取主成矿元素异常和衬度值累加异常,说明地电勘查法找矿的有效性。结合主成矿元素的相关关系,初步建立福建黄田矿区隐伏矿床地球电化学理想找矿模型,并在已知矿区外围开展找矿预测工作,圈定3个有找矿前景的异常区。In order to explore deep concealed orebodies in southwestern Fujian Province, the geoelectro-chemical method was conducted for prospecting. The geochemical data of the mesothermal and hypotherrnal ore-forming elements in Huangtian area are pro- cessed by using the statistical methods, such as contrast anomaly method, accumulative contract anomaly etc in combination with geo- logical background. The result shows that the obvious anomalies of major ore-forming element and accumulative contrast anomaly were distributed on the upper part of known ore-body. It indicated this method is effective for prospecting. Combined with relationship be- tween ore-forming elements, an ideal geoelectro-chemical prospecting model is set up.Finally three anomalous areas were outlined in the peripheral zone for next stage exploration.
