The Geological Characteristics Of Uranium Metallogenic And Metallogenic Regularities In Baizuishan Area,Turpan-hami Basin

The uranium metallogenic type in the Baizhuishan area is an interlayer oxidation zone sandstone type.Although the prospecting is breakthrough,expand the prospecting work and improve the prospecting efficiency is necessary to increase the uranium resource reserves.In order to solve the problems encountered in the process of uranium exploration,it is necessary to study the tectonics,material source and uranium source,sedimentary system,hydrogeology,oxidation zone and different reduction barriers and other ore-controlling factors,need through fieldwork,sample analysis,data processing and comprehensive research.Sum up the uranium mineralization law,forecast for the next exploration work prospects.The study area is located on the slope of the Aiding Lake in the southwestern margin of the Turpan-Hami basin.The tectonic slope zone controls the uranium mineralization concentration area,the Shihongtan anticline and Yingzuiya fault controls the ore body's output site,the tectonic evolution rhythm of the basin controls the uranium mineralization period,Oligocene-Miocene is the main mineralization period(24Ma).The material source is from the south of source area in Jueluotage mountains,and the uranium source is mainly composed of granite and pre-enrichment of stratigraphic.The first lithologic section of the Xishanyao group is dominated by braided river,and the braided river system controls the uranium mineralization,and the braided channel unit controls the distribution of the uranium orebody.The groundwater " supply-runoff-drain" system is perfect,and the uranium belt is located in the groundwater dynamic variation zone and the hydrogeochemical variation transition zone.The interlayer oxidation zone has obvious geochemical zonation,and the uranium ore body is produced in the oxidation-reduction transition zone.The scale,distribution and oxidation degree of the interlayer oxidation zone controls the scale,distribution and strength of uranium mineralization.The organic matter in a variety of reducing barriers plays a leading role in uranium mineralization,and sulfide and coal gas have a certain reduction effect on mineralization.
