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 invisible 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.

Key words: Heitai gold deposit, Typomorphic minerals, Deep and marginal area, Ore finding sign
