The formation of Hengyang basin with large sediment thickness and contrasting of “basin” and “range” is controlled by basement structure, while the extensional movement of caprock can provide ore fluid migration channels and reservoir space. The different stages magmatic hydrothermal movements in the base and surround areas can provide heat source and ore-forming materials. NE-, NW- and EW-trending basement structures intersection control different types of mineralization zonal distribution. Mineral spatial distribution law, ore-forming geological conditions, typical ore deposit characteristics, prospecting criteria and prospecting areas are summarized in this paper.
