秘鲁帕加贡铜矿床地质特征及找矿标志

帕加贡(Pachagon)铜矿位于秘鲁著名的北部斑岩铜矿带上,矿区周边分布多个大型的斑岩型铜矿、铜金矿床。文章通过矿区地质特征、物化探异常、矿石矿物及工程验证综合研究,总结矿床成因,提出找矿思路及找矿标志。同时将矿区的物化探异常特征、蚀变类型、矿物组合、矿物来源等与典型的斑岩铜矿相对比,认为该矿床具有寻找斑岩型铜矿的潜力,值得进一步勘查研究。

Geological characteristics and prospecting criteria of the Pachagon copper deposit in Peru

The Pachagon copper deposit is located on the famous porphyry belt in thenorthern Peru. Many giant porphyry copper and copper-gold deposits occur around the minng area. Based on integrated study on geology, geophysical and geochemical anomaly, mineralogy and engineering test work, the deposit genesis was summarized and exploration strategy and indicators were proposed. By comparing characteristics of geophysical and geochemical anomaly, alteration, mineralization and ore-form metal sources with those of typical porphyry Cu deposits in the region, it is predictedthat there is prospective for exploring porphyry copper deposit.
