The regional hydrologic pattern at the minerogenetic stage of the Longjiao Shan deposit is infiltrational. According to the geologic data and the geochemical characteristics of fluid inclusions,the ore-forming solution,CaCl_2-type water,is the product of the mixing of magmatic water with infiltrational water. The faulting structures constitute the most important media for the migration and precipitation of the ore-forming fluid.
