摘　　要：通过对云南ZC金矿矿床及其外围地质背景、控矿构造、矿化蚀变特点进行对比分析,认为在该金矿北部仍存在较好的找矿前景。通过分析含金矿化带的蚀变特点,发现金与黄铁矿伴生关系密切。通过地质调查、土壤地球化学测量,发现金、汞、锑、砷等多元素伴生关系密切。采用土壤地球化学方法圈出了多个地球化学异常浓集中心;根据含金破碎带具有明显低阻高极化特点,利用大功率激发极化法对有利部位进行详查,根据激电异常特征,结合地质、地球化学异常确定了两个重要异常带,为探矿工程布置提供了物化探依据。最后总结了该矿区地质、地球化学、地球物理找矿标志。Comparative analysis geological background, ore-controlling structure and mineralization characteris-tics of ZC gold deposit and its peripheral, considered that it has good prospecting potential in the north of ZC gold deposit. By analyzing the characteristics of mineralization and alteration zone, that gold and pyrite have a good rela-tionship of associated are found; geological and soil geochemical survey that the gold, mercury, antimony, arsenic and other elements was associated with closed relationship are found. Based on its association a number of geo-chemical anomalies was delineated; rocks and strata electricity statistics show that the gold-bearing fracture zone has a significantly characteristics of low resistivity and high polarizability, by using the high-power induced polariza- tion method on a favorable position to carry out detailed investigation, and combined with the geological, geochemi- cal anomalies identified two important anomalies, and an adequate basis for the exploration engineering;the geolog-ical, geochemical, geophysical prospecting criteria of ZC gold deposit and its peripheral are summarized.
