摘　　要：普角钴金多金属矿位于金平县城南西方向,平距约25 km,矿区包括老刘寨矿段和期腊矿段,目前已在老刘寨矿段探获1条钴矿化体,赋存于橄榄岩中,为岩浆熔离型钴矿体;在期腊矿段探获3条含金银铜铅多金属矿化体,矿化体均为受构造裂隙或破碎带控制的含硫化物石英脉型矿体。区域成矿地质条件优越,矿区内展现出较好的找矿潜力。通过对成矿地质背景、矿床地质特征、矿化蚀变特征总结,浅析矿床成因,为找矿思路提供理论支撑。Pujiao Cobalt-gold Polymetallic Ore is located in the southwest of Jinping County,with a horizontal distance of about 25km.The mining area includes Laoliuzhai Ore Block and Qila Ore Block.At present,1 cobalt mineralization body has been discovered in Laoliuzhai Ore Block,which occurs in peridotite and is a magma liquation-type cobalt ore body.Three polymetallic mineralized bodies containing gold,silver,copper and lead are discovered in Qila Ore Block.All the mineralized bodies are sulfide-bearing quartz vein-type ore bodies controlled by structural fissures or crushed zones.The geological conditions for mineralization in the region are superior,and the mining area shows good prospecting potential.This paper analyzes the cause of deposit formation and provides theoretical support for the next step of prospecting ideas,by summarizing the metallogenic geology background,deposit geological characteristics and mineralization alteration characteristics.
