The gold-silver ores in Shiwo area are structure-controlled alteration-type deposits. Their mineralizations are related to the metamorphic core complex characterized by denudational fault belt in basement rock. The gold-silver ores mainly occur in the range of denudational fault belt, forming the specific ore forming-layer effect. The mineralization is also related to the Yanshanian magmatic activity, which provided accommodate structures mainly consist of fragile faults and shear zone and most part of hydrothermal fluids for the formation of the deposits.
