土壤氡气测量与宽频大地电磁在银额盆地赛尔亥那地区砂岩型铀矿勘查中的综合应用
Comprehensive Application of Soil Radon Measurement and Broadband Magnetotelluric Technology in the Exploration of Sandstone-type Uranium Deposits in Saierhaina Area of Yin'e Basin
摘要
Abstract
In order to identify the potential for sandstone type uranium deposit in Saierhaina area of Yin'e Basin,a comprehensive application of soil radon measurement and broadband magnetotelluric method was carried out.Based on the distribution characteristics of planar radioactivity in the study area and combined with the anomaly distribution pattern of radon concentration in sandstone type uranium deposits,three prospective areas with radon anomalies were predicted.Using broadband magnetotelluric methods,the geological boundaries between the Bayingobi formation and the Permian in the area were delineated,four hidden faults were inferred,and the sand bodies within the Bayingobi formation were identified.Finally,based on the theory of sandstone type uranium metallogeny,the composite parts of two or three ore-forming elements,namely the radon anomaly prospective area,sand body and fault structure,were identified as favorable areas for uranium mineralization.Based on this,three favorable areas were inferred for uranium mineralization.In conclusion,the comprehensive application of soil radon measurement and broadband magnetotelluric methods can achievegood results in the relatively low work level area shuch as Saierhaina and can be recommended in the exploration of sedimentary basins similar to Saierhaina.关键词
