山东泗水县龙湾套地区铜矿成因及找矿前景

Ore Genesis and Prospecting Potential for the Longwantao Cu Deposit in Sishui, Shandong

泗水县龙湾套地区发育大面积新太古代角闪辉长岩,山东省鲁南地质工程勘察院在该区多次进行铜矿普查,通过开展1∶1万地质图草测、1∶1万激电中梯测量、激电测深、1∶1万高精度磁测、槽探和机械岩心钻探等工作,对研究区各类样品进行分析测试,在区内发现了9个铜矿体,矿体直接裸露地表,呈脉状、透镜状,产于角闪辉长岩过渡相内,局部产于内部相中,严格受岩体控制,随岩体向北西侧伏;成因类型为岩浆熔离型含镍铜硫化物矿床。研究结果表明,探讨该区铜矿床成因,分析其找矿前景,对于在该区进一步寻找同类型铜矿床有重要意义。

9 Cu orebodies are found out in Longwantao, Sishui by the Luneng Institute of Engineering Geological Survey. The orebodies are confined as vein and lens in Archean hornblende gabbro and controlled by rockbody. The study indicates that the Cu deposit is a liquid unmixing Cu-Ni Sulfide one.
