【摘要】 长期勘探实践证实,东胜地区侏罗系直罗组砂岩型铀矿与侏罗含煤岩系之间存在密切关系,准确认识这种相关性,对于查明铀成矿规律和指导下一步勘探部署具有重要意义。本文在大量钻孔信息统计的基础上,结合室内测试资料,对东胜铀矿床东段直罗组铀成矿与含煤岩系之间的关系进行了分析,发现:煤层厚度与矿层厚度呈正相关,东胜铀矿床在平面上呈东西向带状展布,其剖面形态受直罗组补给区含氧含铀水与含煤岩系共同控制,含矿砂体是矿体和更是煤层气运移、储集的空间和通道。因此,含煤岩系是东胜地区中侏罗统直罗组砂体赋矿的重要控制因素。更多还原

【Abstract】 Sandstone-type uranium deposit has a close relationship with coal-bearing rocks in the Zhiluo formation of Jurassic in the Dongsheng area though the practice of a long-term exploration,this correlation plays an important role in identifing uranium mineralization and guiding further exploration.Based on numerous information of drillings in this paper, and combined with test data,the relationship between uranium mineralization and coal-bearing rocks in the Zhiluo formation of the Dongsheng area was studied.It showed that,the thickness of coal was positive correlation with the thickness of ledge,Dongsheng uranium deposit distributed on east-west strip in the plane,and profile morphology was controlled by containing-uranium oxygenated water and coal-bearing rocks of recharge area in the Zhiluo formation,containing -ore sandstone was space and access of orebody and coal-bed gas.Therefore,coal-bearing rocks was an important controlling factor of containing-ore sandstone in the Zhiluo formation of Jurassic in the Dongsheng area.更多还原
