摘要：

根据甘肃省白银市Ⅰ号铜铅锌金银矿普查区的地质条件，利用地电化学提取测量、土壤吸附相态汞测量、土壤离子电导率测量、大功率瞬变电磁法等物化探方法进行找矿预测研究。通过对物化探异常的综合分析，结合研究区的地质特征，确定在该区深部具有较好的找矿潜力，在测区内圈定了4个深部找矿靶区，首选3个深度均在300~600 m范围的2-Ⅲ、10-Ⅰ和10-Ⅱ号找矿靶位进行优先验证，据此综合研究结果，可知利用此类物化探方法组合在该区寻找隐伏矿床是可行的，值得广泛推广应用。

Abstract:

Based on geological conditions of No.ⅠCu-Pb-Zn-Ag deposit survey area in Baiyin, Gansu Province, we used the geo-electrochemical extraction method, the soil absorption Hg measurement,the ion conductivity of soil measurement , the transient electromagnetic method and other methods to search deep hidden deposits. According to comprehensive analysis of the geophysical and geochemical anomalies, combined with the geological characteristics of the study area，the paper shows that the potential of mineral deposits is assured in this area, we found four deep ore-prospecting target, recommend three prospecting target site(i.e.,2-Ⅲ、10-Ⅰand 10-Ⅱ) which range from 300~600 m should be verified firstly, according to the findings, we know that the application of such geophysical and geochemical methods to search for concealed ore bodies in this area are available, and they should be used widely.
