摘　　要：金牙金矿床位处滇黔桂被动陆缘,南盘江-右江裂谷盆地桂西北坳陷东北部。本文通过介绍金牙金矿床矿区地质特征、矿体地质特征,分析控矿因素,认为金牙金矿为断裂构造及岩性双向控矿。经过钻探工程控制证实矿区断层往东部持续延伸,且为主要控矿构造,工程对深部矿体的追索仍未尖灭,矿体延伸有一定的稳定性和规模,下步往东侧深部找矿潜力大。The Jinya gold deposit is located in the passive continental margin of Yunnan,Guizhou and Guangxi,in the northeastern part of the northwest Guangxi depression in the Nanpanjiang-Youjiang rift basin.This article introduces the geological characteristics of the Jinya gold deposit,analyzes the controlling factors,and believes that the Jinya gold deposit is controlled by a fault structure and lithology in both directions.,After drilling engineering control,it has been confirmed that the fault in the mining area continues to extend towards the east and is the main controlling structure.The exploration of the deep ore body by the engineering has not yet been pointed out,and the extension of the ore body has a certain stability and scale.The next step is to explore the deep ore body on the east side with great potential.
