摘要
对塔里木盆地孔雀河斜坡带主要地质单元(岩石)的电性、密度、地震波阻抗等参数特征进行了分析研究,将地面γ能谱测量、土壤氡法、瞬变电磁测深、浅层地震勘探等方法,在这一地区找铀矿的应用效果综合评价后,认为本区具有开展多种地球物理方法的物性前提。孔雀河斜坡带北部盖层产状平缓,具有冲积扇-河流相沉积体系,且有放射性元素富集的迹象,是砂岩型铀矿成矿的有利地区。
This papper analysed and studed the geophysical characteristics,such as electric and density and seismic wave impedance parameters of strata（rocks）in Kongquehe monoclinal area of Tarim basin.Based on the comprehensive estimate of application affects of geophysical method,such as ground γ-spectrometric,soil radon survey,transient electric and magnetic method and shallow seismic prospecting etc,it was believed that the study area has favorable physical-premises of manifold geophysical prospecting for sandstone-type uranium deposit.The cover strata are sligtly dipped and belong to alluvial fan-fluvial facies,and bear the trace of radioactive elements concentrating,therefore the area is favourable for the metallegenesis of in-situ leachable sandstone uramium deposit.
