Replacement-style epithermal gold deposit, occurring in mafic volcanic rocks of the Yamansu Formation along the Kushui fault. The E-W-trending shear zone is composed of a series of mylonitized rocks. In addition, a set of NE- and NW-trending post-ore conjugate brittle faults is developed in this area. The major ore veins are located in the transition zone between intense and moderate ductile strain. Ore zones include magnetite- and sulphide-rich auriferous quartz veins and massive lenses, as well as barren quartz-carbonate or carbonate veins. The sulphide-rich veins occur either as large vein swarms or as fine stockworks in highly altered volcanic rock. Approximately 100 to 300 m wide hydrothermal alteration zones surround the orebodies, which can be divided into three zones: (1) an inner zone of altered mafic rocks, part of the orebodies themselves, consisting of quartz, chlorite, pyrite, chalcopyrite and magnetite; (2) a middle zone, comprising a pyrite-bearing phyllic and/or a sericitic alteration assemblage; and (3) distal alteration, characterized by a sericite-chlorite assemblage. Vertically, the zoning consists of Au-Ag-As ores in the upper 170–200 m and Cu-Pb-Zn ores below this depth.
