摘　　要：湘西南金矿主要有石英大(单)脉型和石英细(网)脉型两类。赋存于上元古界板溪群火山-陆源碎屑沉积含金建造中。金矿化严格受脆-韧性剪切带控制。地质-遥感成矿特征揭示,该区金矿具有较大的找矿潜力。研究认为,该区成矿类型除石英脉型金矿外,还应加强破碎带蚀变岩型金矿的找矿研究工作。The main types of gold deposit in southwestern Hunan are quartz vein type （single vein）and quartz veinlet type（network veinlet）,which are located in Banxi group gold bearing formation of volcanic-terrestrial clast deposition of Later Proterozoic series and are strictly controlled by brittle-ductile shear zone. The geological remote sensing characteristics show that there is great potential for the prospecting of gold deposit in the area. Prospecting research should focus on the fracture zone-altered rock deposit besides quartz vein type gold deposit.
