Abstract:Through analysis and study on geology, oreforming elements and isotopes geochemical characteristics of Liujiapuzi Langdonggou gold and silver deposit, it is found that the faults with the trend of EW and NE were main orebearing structures, the best prospecting elements combination of front halo was AsSbZn, superore halo was AuAgPbHg, and tail halo was NiCuCo. Metamorphic rock series of Proterozoic Laoling group in the ancient base provided rich material sources for mineralization, and Yanshanian tectonic magmatic activities provided oreforming materials as well as thermodynamic. Liujiapuzi Langdonggou gold and silver deposit should be classified into midlowed hydrothermal and structural fissure filling type gold and silver deposit associated with super hypabyssal intermediateacidic magamtic rocks in late Yanshanian.
