| Abstract: | Dongping gold deposit in alkaline intrusives and Xiaoyingpan gold deposit in metamorphic rocks are both belong to reworked genesis related to meteoric water, Their mineralizing mechanism includes three processes: activation, migration, and deposition of gold. Gold in host rocks is activated by heated meteoric water (formation water contained in Xiaoyingpan gold deposit), then migrated mainly in the form of Au (HS). In addition, colloform in the Dongping gold deposit is important to An migration. Adsorption of minerals, mixture of fluids (Xiaoyingpan gold deposit ),and immiscibility of fluid (Dongping gold deposit) are principal factors to lead to deposition and enrichment of gold. |
