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。
