Formation and evolution of Jurassic groundwater and its relation to interlayer oxidation zone development in Tuha Basin

The formation, development of interlayer oxidation zone has close relation to the formation and evolution of groundwater. It is studied that the evolution history of Jurassic groundwater by use of palaeohydrogeological analysis method in Tuha Basin in Xingjiang of China. The Jurassic aquifers lithodeme can be divided into three hydrogeological stage. The reformation process of terra static pressure system and water static pressure system on deposition water is quantitatively confirmed. The author also calculate the alternate intensity of squeeze water and penetration water. Penetration water pressurized system area in south basin is the beneficial part of developing interlayer oxidation zone. The interlayer oxidation zone is a zone of uranium mineralization
