摘　　要：可地浸砂岩型铀矿床上方异常信息微弱,直接寻找具有一定的困难,为了准确寻找可地浸砂岩型铀矿,笔者提出借助多源遥感图像所提取的岩性、构造、矿化蚀变等信息来提取可地浸砂岩型铀矿源相关信息,并以鄂尔多斯盆地杭锦旗地区为例,依据提取的信息,对其成矿地质构造环境和可地浸砂岩型成矿条件进行了详细分析和阐述,初步预测了研究区的铀成矿有利区域。Due to the insufficiency of the information concerning the in-situ leachable sandstone type uranium deposit, it is very diffcult for the airborne radiation method to detect the uranium deposit. In order to solve this problem, the authors hold that the uranium deposit information can be obtained by extracting lithologic character- istics, structures and alteration information from RS images. With the area between Hangin Banner and Dongsheng in Ordos basin as an example, the authors analyzed in detail the metallogenic geological and structural environ- ment and the ore-forming conditions of the in-situ leachable sandstone type uranium deposit and, on such a basis, forcast the favorable area for uranium mineralization.
