摘　　要：洒拉冲金矿处于我国卡林型金矿重要成矿区——滇黔桂"金三角"区东南隅的广南与广西毗邻地区。控矿因素主要为沿洒拉冲复式背斜核部及翼部发育的NWW—SEE向断裂破碎带,为脆性剪切带热液蚀变型金矿。文中从区域地质背景入手,系统介绍矿金矿矿床地质特征,分析矿床成因及找矿标志。Salachong Au deposit is in the neighboring area of Guangnan to Guangxi in SE section of Dian- Qian-Gui ＂Au triangle＂ - the important Carlin-type Au metallogenesis region in China. The main ore control factor is the HWW-SEE fault fracture zone of the core and limb of Salachong anticlinorium, belonging to the brittle shear zone hydmthennal alteration type Au deposit.. In this paper, we show the geological feature of Au deposit, and have an analysis of the genesis and prospecting criteria ore deposit according to the regional geological setting.
