1 Geological feature of deposit The Jinya gold deposit is a fine disseminated gold mine. It occurs in sandstone and mudstone ofMiddle-Triassic Baifeng Formation, which is located at the margin of Late Paleozoic carbonate platform. Itwas controlled by the fracture zone, cleavage zone and fissure zone. The gold deposit has 15 orebodies,which are displayed as beds, lens and veins. The dominating minerals with gold are pyrite and arsenopyrite. The gold mainly occurs as submicroscopic intergranular gold. Low-to-moderate temperature (130-305℃) wall-rock alterations are mainly silicification, pyritization and arsenopyrite, also includes realgarization, carbonation (calcite, dolomite), sericitization and argillation (kaolinite, pyrophyllite). It wasformed after undergoing the sedimentary diagenetic period, hydrothermal mineralization epoch (2.3 Ma)and supergene mineralization.
