| 摘 要： | 伊勒门盆地是典型的中新生代山间盆地。文中分析了盆地盖层下白垩统巴彦花组的沉积体系特征及砂岩型铀矿找矿远景。认为辫状河、三解洲砾岩、砂砾央及砂岩层是寻找潜水层间氧化带砂岩型铀矿的有利层位，初步确定达来隆起带北西侧、查干台格布其狭长凹陷带及包林布其南部地区3片潜水层间氧化带砂岩型铀矿远景区。

| Abstract: | Yilemen basin is a typical Mesozoic intramountain one. This paper analyses characteristics of depositional system and the prospect of sandstone-type uranium deposit in the sedimentary cover of the Bayanhua Formation,Lower Cretaceous. Authors suggest that the conglomerate,sandstone-conglomerate and sandstone beds of braided stream and delta are favourable horizons for locating phreatic and interlayer oxidation zone sandstone-type uranium deposits,i.e.the northwestern side of Dalai uplifted zone,the Chagantaigebuqi narrow sag,and the southern area of Baolinbuqi. |
