摘　　要：提出了在沉积盆地内识别岩性的光能谱融合新技术,在鄂尔多斯盆地东北部取得了较好的应用效果;提出了3种有利于增强深部铀矿致异常信息的放射性弱信息提取方法,在鄂尔多斯盆地东北部东胜砂岩型铀矿床取得了较好的试验效果。A new kind of integrated technique between remote sensing and gamma energy spectra is put forward, which can recognize lithology in the sedimentary basin and has already yielded good application effects in northeastern Ordos basin. Three kinds of radioactive weak information extraction methods are also put forward, which are effective in strengthening the deep uranium anomaly information related to mineralizaiton. Good trial results were acquired above the Dongsheng uranium deposit in northeastern Ordos basin.
