Analysis of Uranium Metallogenic Conditions and Prospection Direction in Lujing Sag,Badan Jaran Basin
In order to explore the prospecting direction and type of ore uranium depost and guide ore uranium depost in the Badan Jaran Basin and its surrounding areas,this paper delineated the key ore exploration horizons by analyzing the structure,sedimentary construction,and uranium mineralization and transformation characteristics of the Lujing Sag in the Badan Jaran Basin.Through systematic analysis of uranium source,tectonic evolution,paleoclimate environment,hydrogeology,lithology of target layer,epigenetic alteration and uranium mineralization characteristics,It was considered that the Lujing Sag was rich in uranium sources,the target layer developed mud-sand-mud structure,groundwater recharge-run off-discharge system,and the interlayer oxidation zone was well developed,which laid the prerequisites for sandstone type uranium mineralization.Combined with the uranium mineralization clues revealed in the current borehole,it is confirmed that the Lujing Sag has uranium mineralization potential and prospecting space.The main prospecting horizon is Lower Cretaceous Suhongtu Formation,and Lower Cretaceous Bayingebi Formation is worth to study more.The main ore prospecting structure of Suhongtu Formation is the river way wing and the searching type is interlayer oxidation zone.The ore prospecting position of Bayingebi Formation is mainly the fan delta front,searching for phreatic oxidation syn-sedimentary uranium deposits.
