Medium-sized Au-Ag epithermal vein deposit, controlled strictly by faults and fracture zone, and behaving as veins occuring in andesite lava and lava-pyroclastic rock of the Early Cretaceous Jingouling Formation, or as disseminates or veinlets in alkalic granite and subtrachyte andesite of the Yanshan period, and in strata of the Jingouling Formation. The deposit minerals are sulphide-poor type and display xenomorphic-idiomorphic, cryptocrystalline, metasomatic, filling, colloid and cataclastic textures and occur in breccia, disseminations, crystal vugs and veinlets. Alteration is closely related to deposition and includes silica alteration, carbonate alteration, alteration to zeolites, and pyrite beresite alteration. At greater depth of the deposit, alteration to adularia dominates.
