可地浸砂岩型铀矿盲矿识别模式

伊犁盆地南缘是典型的可地浸层间氧化带砂岩型铀矿产出区，近年来诸多单位对其控矿因素、成矿环境与成矿远景进行了研究。由于此类型矿床产出部位地表覆盖严重、多属盲矿，因此对其识别定位既是找矿工作中的技术关键，亦是难点。受核工业北京地质研究院开放实验室资助，笔者以伊犁盆地南缘为研究对象，对可地浸层间氧化带型砂岩铀矿盲矿的识别模式进行了专项研究。

RECOGNITION MODEL FOR IN SITU LEACHABLE SANDSTONE TYPE URANIUM DEPOSIT

At present, the southern flank of the Yili basin is a typical area for the occurrence of in situ leachable interlayer oxidation zone type sandstone hosted uranium deposits in China. A lot of research work focused on the ore controlling factors, metallogenic environment and metallogenic prospect has been carried out in recent years. Owing to the fact that such deposits being mostly concealed ones are usually covered by thick overburden, the recognition of the occrrrence for such deposits becomes both the technical key and the hard point in prospecting. Supported by the Open Laboratory of Nuclear Energy Resources Research, the authors taking the southern flank of the Yili basin as an example performed a special research on the recognition model for concealed in situ leachable sandstone type uranium deposit.
