摘　　要：The exploration depth of sandstone-type uranium deposits worldwide is mostly less than 700 m,and most of them occur in strata of fluvial facies(Adams et al.,1981;Jin et al.,2016;Hou et al.,2017).Only a few small uranium deposits have been reported in aeolian depositional environments(Isachsen et al.,1955;Li et al.,2001).In the Pcngyang Jingchuan region of the southwestern Ordos Basin,uranium ore bodies with large thickness and high grade in the aeolian sandstone of the Luohe Formation were newly found at depths from 700 to 1500 m,which have laid the foundation for increasing the uranium resources significantly in the Ordos Basin.
