摘要
湘西南金矿主要有石英大(单)脉型和石英细(网)脉型2类,赋存于新元古界板溪群火山-沉积含金建造中.金矿化严格受脆-韧性剪切带控制.地质-遥感成矿特征表明,该区金矿具有较大的找矿潜力.除石英脉型金矿外,还应加强破碎带蚀变岩型金矿的找矿研究工作.
There are two types of gold deposits in Southwestern Hunan Province. One is large （single） quartz vein type. The other is thin （network） quartz vein type. The ore occurs in the volcano-sedimentary gold-bearing formation of Neo-proterozoic Banxi group. Gold mineralization is strictly controlled by brittle-ductile shear zone. The metallogenic features from geological remote sensing show that the area is an idea prospect target with great potential. More attention should be paid on the research of fracture zone altered rock type of gold, besides the quartz vein type.
