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,与闪长岩密切相关的热液型金矿床。

Abstract: Santai gold deposit locates in the northeast section of Jilin Daheishan strip barrier.7 gold veins,which occur in Palaeozoic Hulan group schist,are found in the deposit.The veins are controlled by NW ductile-brittle structure belts.Sometimes,the orebodies edge away and reappear.The orebodies associate with diorite and there are cylindrical,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.
