Abstract
This paper used the PHREEQC model procedure to simulate the mineralization hydrogeochem-ical feature of the groundwater in research area. By confirming the uranium occurrence modality, the saturation index (SI) and the reaction condition index (RCI) of the uraninite and other hydrogeochemical environment parameters, the relations of uranium in layers to the Eh, pH and uranium concentration in groundwater was analyzed and had proven that the Eh of groundwater is the most important controlling factor over uranium mineralization; the hydrogeochemical condition for the formation and localization of sandstone deposit was also studied and discussed to elaborated the uranium migration and the precipitation pattern. The above research can provide important criterior for the application of hydrogeochemical method in the predication and localization of sandstone-type uranium deposit.关键词
