摘　　要：通过野外实地勘查和近几年钻孔样品测试数据综合统计,结合三角图图解和地球化学数据组合对比,分析侏罗系头屯河组、西山窑组、三工河组、八道湾组赋铀层位砂岩碎屑矿物组分,并对不同地段不同层位铀矿化对比、剖析赋铀层位层间氧化带附近铀矿化特征,总结了研究区地球化学特征及氧化带特征与铀成矿规律。Combined with triangle illustration and comparative analysis of geochemical data field investigation and statistics of test and analysis of drill core samples for recent years are conducted to analyze detrital:mineral components of U-bearing strata in Triassic Toutunhe,Xishanyao,Sangonghe and Badaowan formations.The U-Mineralization at different locations and stratum is compared and the mineralization near interformational oxidation zone within the U-bearing stratum discussed.Then are summarized characteristics of geochemistry of the study area and the mineralization zone and the U-metallogenic law.
