Analyses on paleo hydrogeological conditions of sandstone type uranium metal-logeny in Wennite depression of Erlian Basin
On the base of analyzing features of basement,cap structure of Wunite Depression in Erlian Basin,the paleoclimate conditions of depression are studied,for example,underwater's formation and development his-tory,forming and development process,reformation effect of geostatic pressure system and hydrostatic pressure on underground water.The terrastatic moving direction contrasts that of oxygenated and uranium-bearing water from recharge areas of the basin margin.Two different property of underwater meet on the mixed parts where hydrodynamic condition and hydrochemistry environment varies during runoff process.Uranium enriched and mineralized in these varied parts.Uranium metallogenic favorable periods and layers are forecasted by this way.
