摘要
河台大型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，首次发现含金碲铋矿。
The gold in large-scale Hetai gold deposit exists in two forms:isolate gold-mineraland dispersion phase,The former is mainly native gold,which occurs in inclusion,intracrys-talline failure and crack.ICP,electron microsprobe analyses and Au X-ray plane scanning showthat some of the gold may occur in the crystal lattice of sulfides as dispersion phase。Gold-bear-ing tellurobismuthite was first discovered in the mining area。
