摘要
Abstract
With the theory of hydrogenic uranium deposit, the conditions of uranium source, geological structure, hydrology, sedimentation and paleo-climate for the metallogenesis of sandstone type uranium deposits in the northeast uplift of Songliao Basin are analyzed. The following geological conditions are considered favorable for the metallogenesis of sandstone type uranium deposits in this area: Influenced by tectonic movements, stratum uplifting and erosion, a structural inlier is formed in the area; A SW-trending slope belt is developed in the margin of the basin; The well developed sand bodies of fluvial facies and delta facies are deposited; an interlayer zone of mudstone-sandstone-mudstone is developed with permeable bed and impermeable bed; The supply-passage-discharge system is complete with favorable hydraulic condition and the characteristics of secondary seeping artesian basin. As a result, the prospects of uranium in the northeast uplift of Songliao Basin are encouraging.关键词
