摘要: SHIRINK2 铜矿位于伊朗克尔曼地区南部,地处伊朗重要的斑岩铜矿成矿带,成矿带内 铜矿多与火山及侵入活动、断裂构造密切相关,成矿条件良好。矿床已发现的3 条铜矿体主要赋存于 网脉状石英脉、粉砂岩和页岩层理裂隙面及蚀变安山岩中,青磐岩化、硅化、黄铁矿化等围岩蚀变与 铜矿化关系密切。结合区域成矿地质背景、矿区地质特征及相关勘查成果,发现铜矿体因受北东向 走滑断层控制,呈脉状展布,矿化蚀变带与北西向区域断褶带方向一致。通过矿石物相及化学分析, 发现矿床属斑岩型铜矿床,铜矿化与该区域火山岩浆带密切相关,北西向矿化蚀变带及北东向断裂 带附近为矿化富集区,找矿潜力较大,为进一步探求斑岩型铜矿床提供依据。

Abstract: SHIRINK2 Copper is located in the south of Kerman area,Iran. It is located in the important porphyry copper metallogenic belt in Iran. The copper deposits in the metallogenic belt are closely related to volcanic eruptions,intrusive activities and faulted structures,and the metallogenic conditions are good. The main ore bodies of the three copper deposits have been found mainly in the quartz vein,siltstone, shale bedding fissure surface and altered andesite,the wall rock alteration such as qingpanitization,silicification and pyrite mineralization is closely related to copper mineralization. Combined with the regional metallogenic geological setting,geological characteristics of the mining area and related exploration results, it is found that the copper body is controlled by the northeast strike-slip fault,and the mineralization alteration zone is in the same direction as the northwest regional fault-fold zone.Through the analysis of ore facies and chemistry,it is found that the deposit belongs to porphyry copper deposit,copper mineralization is closely related to the volcanic magmatic belt in this region,and the area near the NW mineralization alteration zone and the NE fault zone is the rich mineralization area with great prospecting potential,which provides the basis for further exploration of porphyry copper deposit.
