摘　　要：本文综合分析了大观金矿的地质及地球化学特征。提出矿区T/P接触带为主要导矿构造和次要容矿构造,南北向断裂带为主要的控矿与容矿构造和次要导矿构造,矿体主要受陡倾斜断裂控制;含矿岩石主要为硅化岩石。岩石和土壤地球化学测量显示Au、As、Sb、Hg和Ba前缘晕元素组合特征,对比区内盆地相卡林型金矿床控矿要素,认为大观金矿深部有较好找矿前景。In this paper, the geologic and geochemical characteristics of Daguan gold deposit are studied, it＇ s thought that T/P contact zone is the major transmissive structure and the secondary existing structure, SN fracture zone is the major ore control and existing structure and secondary transmmsive structure, the orebody is controlled by steep angled fracture, the ore-bearing rock is silicified rock. The measurement of rock and soil geochemistry shows the elements composition features of Au, As, Sb, Hg and Ba, the ore-controlling factors of Carlin-type gold deposit in this area is compared, it＇ s thought the deep Daguan gold deposit has good prospecting.
