The Analysis Of Ore-forming Factors Of Saihan Group In-situ Leachable Sandstone-type Uranium Mine In Al Tara's Sunken Areas

Uranium is an important clean energy,but also has important strategic significance of military and political,in north China Asin uranium resources in recent years have great discovery,ushered in the new situation of the research work.Ased on the in-situ leachable sandstone-type uranium deposits as the main research object,the al tara sag of Erlian Asin in Inner Mongolia to carry out the uranium metallogenic factors analysis,the regional geology,dynamics of Asin uranium geology,sedimentology,and other multi-disciplinary knowledge,and using the "six integration" of uranium deposits(or points)evaluation method,has carried on the comprehensive analysis and research in the studied area.For the purpose of this article below cretaceous Saihan group layer,emphatically from the uranium source,structure,hydrogeology,sand body characteristics,lithologic facies conditions,six aspects are studied epigenetic alteration phenomenon,that the sag with uranium metallogenic potential,purpose layer with mud-sand-clay structure,subdivide the 3 layer of sand body and carries on the analysis and evaluation.Further analyses the uranium anomaly intensity from the microscopic view and formation property relations,confirmed that the interlayer oxidation zone,exploratory forecasts the oxidation front position,analyses the uranium metallogenic conditions and law research,draw a length of 10.88 kilometers,3.0 kilometers wide,covers an area of 32.64 square kilometers area,has a guiding significance to uranium resources exploration and evaluation of the sag.
