摘　　要：在系统分析准噶尔盆地西北缘侏罗系构造演化、岩性岩相、氧化带发育特征、油气首次侵入时间及含铀含氧水作用期次基础上,认为准噶尔盆地西北缘侏罗系砂岩型铀矿找矿工作应以寻找八道湾组和西山窑组中古层间氧化作用所形成的铀矿化为主要找矿方向,目前在克拉玛依发现的铀矿化为近现代地下水层间氧化作用结果,受油气渗出作用控制,地下水渗入作用受到限制,形成的层间氧化带及铀矿化规模有限。By analyzing the tectonic evolution,facies lithology, characteristic of oxidation zone, first time of oil and gas invasion and the times of Uranium containing oxygenated water, in Northwest Margin edge of Junggar Basin,suggest that Uranium mineralization which controlled by Paleo-interlayer oxidation in BaDaoWan and XiShanYao formantion is the main prospecting direction,and the Uranium mineralization,which was founded in Karamay, was controlled by Modem oxidation,and the scale of uranium mineralization was small.

关 键 词：准噶尔盆地西北缘 侏罗系 古层间氧化 砂岩型铀矿 成矿远景
