摘要
白音套海盆地位于扎兰屯铀成矿远景带中部,处于华北板块与西伯利亚板块交汇部位,经历了中新生代多旋回构造-岩浆作用,具有较大的找铀前景。通过分析盆地基底、盖层、构造、热液蚀变、铀矿化特征等方面铀成矿地质条件,并与邻区俄罗斯斯特列措夫铀矿田进行对比,认为盆地与其有相似成矿条件,具找矿潜力,指出盆地中部基底隆起区NE向深大断裂的次级断裂带与暗色岩墙脉体发育部位,盆地内部深大断裂的次级断裂带交汇部位与火山机构复合部位,且次火山岩体厚度大或体积大、分布广的地段为有利找矿部位。
Located in the middle of the Zhalantun uranium metallogenic prospect belt and the overlapping area of the north China plate and the Siberian plate.Baiyintaohai volcanic basin has been experienced by Meso-Cenozoic multi-cycle tectonic-magmatic activiation,and is believed to be the favorable region of volcano hydrothermal type uranium deposit.By analyzing the uranium metallogenic conditions of basement,overlayer,structure,hydrothermal alteration,uranium mineralization and comparing to that of streltsovka uranium ore filed,Baiyintaohai basin is believed similar metallogenic geological conditions to Streltsovka uranium ore filed.The prospect area are the overlapping place of melanocratic vein and derivative fault of northeast trending deep-seated fault of uplifted zone of basement in the middle of the basin,and derivative fault of northeast-trending deep-seated fault and volcano-tectonic and sub-volcanic rock inside of basin.
