Study on aeroradiometric weak uranium anomaly above in-situ leachable sandstone-type uranium deposit and its prospecting significance

Based on the serious study on aeroradiometric data above uranium deposits No.511 and No.512 at the southern margin of Yili basin,Xinjiang elevation of uranium content above uranium ore bodies has been discovered.Therefore,a new concept of weak uranium anomalyabove in-situ leachable sandstone-type uranium deposit has been proposed.Moreover,on the basis of geogas migration mechanism and the theory of radon relay migration,the formation mechanism ofweak uranium anomalyis discussed,and the extraction methods of aeroradiometric uranium anomaly are introduced,Finally,it is concluded,thatweak uranium anomalycan be fully detected by high-sensitive aeroradiometric method,and that uranium anomaly can be applied to the early-stage prospecting prognosis as a kind of direct indication of information.
