| Abstract: | This paper studies supergene geochemical process of gold from the hydrogeochemical point of view. It is researched that the species of gold in water of Maopai area and their migration and precipitation conditions by applying the thermodynamic method. The result showes that Au(S2O3) is the major species of gold in water in the working area. The forming conditions of placer gold in Maopai area are also concerned with. |
