为了解决干旱荒漠区的深部找矿问题和探索地电化学法在干旱荒漠区寻找隐伏金属矿床的可行性,在甘肃白银银硐沟勘查区运用地电提取、土壤离子电导率等多种找矿方法来找寻隐伏的矿体.以9×10~(-6)、18×10~(-6)、36×10~(-6)三级浓度分带划分,圈出22个地电提取Cu异常;以7.25×10~(-6)、14.5×10~(-6)、29×10~(-6)三级浓度分带划分,圈出32个地电提取Zn异常;以100、200、400 μS/cm三级异常强度分带划分,圈出11个电导率异常.按照异常的规模、大小、强弱、变化、吻合程度、异常出现的地质部位等因素,将测区内的综合异常划分为两类5个综合异常靶区,其中Ⅰ类靶区2个,Ⅱ类靶区3个.

To order to search deep hidden deposits in the arid desert area and the feasibility of geoelectrochemical method to find buried metallic deposits,the geo-electrochemical extraction methods are used.Using 9×10~(-6),18×10~(-6) and 36×10~(-6) as the three content belts,twenty-two Cu exceptional areas are found.Using 7.25×10~(-6),14.5×10~(-6) and 29×10~(-6) as the three content belts,thirty-two Zn exceptional areas are found.Using 100,200 and 400 μS/cm as the three content belts,eleven soil ionic conductivity exceptional areas are found. According to the scale,size,strength,change,match degree and the geological location of the anomalies,five targeted regions are found in this area,and divided into two types:two first-class targeted regions and three second-class targeted regions.
