摘　　要：金蟾山金矿位于内蒙古喀喇沁旗安家营子花岗岩体内的断裂中,矿区断裂构造分为东、西两个断裂群,以NNE向和近SN向脆性断裂为主,成群分布,控矿断裂形成于135～126Ma期间;成矿前表现为两组共扼的节理,成矿期近SN向和NNE向断裂、主断裂与派生断裂共同控矿。Goldentoad mountain gold depositis located in fractures within Anjiayingzi granitic mass. Two fracture swarmps occur in east and west of the mine area respectively and are dominated by fractures tren ding NNE and SN. The ore control fractures were formed in 135-126 Ma period. Conjugate joints are pre- mineralization structure and fractures trending SN and NNE and rederivel fractures symineralization.
