准噶尔盆地东部北缘侏罗系砂岩型铀矿成矿条件分析

摘要

Based on the drilling data in the northern margin of Eastern Junggar Basin,there are large scale continuous distribution of the early Jurassic.Based on the comprehensive analysis of the tectonic evdution,palaeoclimate,lithology and lithofacies,development of oxidation zone,uranium source condition,hydrogeology.etc and with the verify of the drilling which have thick coal seam with radioactive anomaly high,the article founds the economic uranium orebody,indicates the direction of uranium deposit.%结合煤田钻孔资料,以“煤、铀兼探”为契机,对准噶尔盆地东部北缘大量煤田钻孔进行综合研究,发现侏罗系八道湾组上段具规模较大连续分布的放射性异常.对构造演化、古气候、岩性岩相、氧化带发育、铀源条件及水文地质等进行系统研究,并对放射性异常值高、厚度大的煤田钻孔进行验证,发现工业铀矿体,由此指明铀矿勘查工作方向.
