摘　　要：三台金矿床位于吉林大黑山条垒的北东段。该矿床已发现7条金矿脉,均赋存于古生界胡兰群片岩中,矿脉受北西向韧脆性构造带控制。矿体尖灭再现,与闪长岩伴生,呈柱状、脉状或不规则状产于矿脉内,矿化分为4个阶段。综合分析表明,三台金矿床为受韧脆性构造控制。Santai gold deposit locates in the northeast section oi Jilin Daheishan strip barner. 7 gold veins, which occur in Palaeozoic Hulan group schist, are found in the deposit. The veins are controlled by NW ductile-brittle struc- ture belts. Sometimes, the orebodies edge away and reappear. The orebodies associate with diorite and there are cy- lindrical, vein type and irregular orebodies in the veins. There were 4 mineralization phase. Comprehensive analysis shows that the deposit is a hydrothermal fluid gold deposit controlled by ductile-brittle structure and closely related to diorite.
