摘    要:广南县老寨湾金矿位于滇、黔、桂“金三角”重要成矿区带上,金矿体矿体呈似层状赋存于断层构造破碎带或层间构造破碎带中,构造控矿明显。矿体围岩均为下泥盆统坡松冲组第一段(D1ps1)硅化石英砂岩;矿床成因属中-低温热液叠加改造型金矿床,断层构造、硅化等矿化蚀变及地球化学异常是重要的找矿标志。

关 键 词:构造控矿  热液型矿床  找矿标志  云南广南老寨湾

Abstract:Laozhaiwan Au deposit in Guangnan is in the important Dian-Qian-Gui“Au Triangule”metallogenesis zone.The Au orebody is stratoid in the fault structure zone or interlayer structure fracture zone,ore control of structure clear.The Wall rock of orebody is Lower D Posongchong FormationMember 1(D1ps1)silicified quartz sandstone.The deposit is the middle-low T hydrothermal superimposition reformation Au deposit in genesis.The fault structure,silicification,etc metallogenesis alteration and geochemical anomaly are the important prospecting criteria.
Keywords:Ore Control of Structure  Hydrothermal Deposit  Prospecting Criteria  Laozhaiwan,Guangnan,Yunnan
