【摘要】 新疆塔里木盆地东北缘孔雀河斜坡带形成于古生代,面积较大,后期地质发展过程中相对稳定,铀源丰富,具一定找矿前景.由于被第四系大面积覆盖,寻找砂岩型铀矿难度大.本文利用区域铀成矿地质调查、浅层地震、放射性物探及区域水文地质调查取得的成果,对地浸砂岩型铀矿区域成矿条件进行初步研究,认为本区成矿可能性较大,成矿有利层位是上新统库车组和中新统康村组,老开屏单斜带是铀成矿有利地段.更多还原

【Abstract】 The area of the Kongquehe monoclinal area in northeast rim of Tarim basin is large.It is formed during Paleozoic,geotectonic environment is relatively stable after the formation,and is bundant U-sources.There are more prospecting perspective in the area.But prospecting sandstone U-deposits in the area is difficult because of Quaternary cover in this area is severe.Based on the obtained informations that regional uranium deposits investigation,shallow seismic prospecting,radiometric survey and regional hydrogeological conditions investigation etc.Analysed and researched regional conditions of insitu leachable sandstoneuranium metallogenesis.The author think of that study area faborable strata for uranium oreformation are Pliocene series Kuche formation and Miocene series Kucun formation.Region of favourable for the sandstone uranium metallegenesis are put forward in the Laokaiping monoclinal area.更多还原
