摘　　要：河台金矿床金的赋存状态呈独立矿物和分散状态两种,前者以自然金为主,有包裹金、晶隙金和裂隙金,后者则存在于硫化物晶格中。通过分析矿区矿物,找到直接和金矿化有密切关系的标形矿物,烟灰色Ⅱ世代含金石英、半自型-它型晶含金黄铁矿及含金菱铁矿。Aurum of Hetai gold deposit occurs as independent mineral gold and invisible gold. Most of independent mineral gold occurs as natural gold, like enclosure, intergranular, and crevice gold. And invrsible gold mineral occurs inside sulfide facies. According to analysis of minerals, the author find typomorphic minerals, which have a close relationship with the gold mineralization directly and also are the ore finding signs in this district, such as the auriferous grey quartz formed in second stage, auriferous hypidiomorphic-xenomorphic granular pyrite and auriferous siderite.
