摘要
文章通过分析潘公潭铀矿床的成矿特征和成矿条件,认为雪峰山隆起带西北缘地区的铀成矿作用主要受赋矿地层(下寒武统牛蹄塘组)、NE向断裂、断陷红盆和寒武纪岩相古地理等因素控制。区域化探表明,Mo、V和Ag等元素与铀成矿关系密切,对指导找矿有重要作用。根据全国铀矿资源潜力评价技术要求,通过总结、归纳区内碳硅泥岩型铀矿成矿地质要素和预测要素,采用固体矿产矿床模型综合地质信息预测技术,预测了有利成矿远景区,为该区铀矿地质勘查提供依据。
Based on the characteristics and ore-forming conditions in Pan'gongtan deposit,the ore-hosting bed(Niutitang formation of Lower Cambrian),NE striking faults,downfaulted red basin and Cambiran lithofacies paleogeography are regarded as the primary ore-controlling factors in the region.According to regional geochemical exploration,Mo,V and Ag are closely related to uranium metallogenssis.According to the technical request in National Potential Evaluation of Uranium Resources,geological conditions and prognosis factors for the evaluation carbonaceous-siliceous-argillaceous rock type uranium deposit was summarized in the northwestern margin of Xuefengshan uplift belt.The uranium potential of carbonaceous-siliceous-argillaceous rock type has been estimated in the area,which can provide scientific basis to uranium exploration and strategic target selection.
