摘　　要：通过对介拉斯台火山断陷盆地铀矿化显示、控矿因素及铀成矿机制的调查研究,认为盆地铀成矿地质条件优越,构造岩浆活动强烈,主要富铀岩系为上侏罗统满克头鄂博组、白音高老组中酸性、酸性火山岩,构造裂隙十分发育,热液蚀变强烈,该盆地是寻找火山岩型铀矿床的有利远景盆地,盆地内火山机构与断裂复合部位、蚀变发育及岩石物化特性反差明显部位为铀重点找矿部位。Based on the investigation and study of uranium mineralization display, ore-controlling factors and uranium mineralization mechanism in Jierastai volcanic fault basin, it is believed that the basin has superior uranium mineralization geological conditions, strong tectonic magmatism, and the main uranium-rich rock series are the acidic and acidic volcanic rocks in the Upper Jurassic Manketou’ebo Formation and Baiyingaolao Formation, with well-developed tectonic fractures and strong hydrothermal alteration. The basin is a favorable prospective basin for searching for volcanic-type uranium deposits, In the basin, the composite part of volcanic mechanism and fault, the part with obvious difference in alteration development and rock physical and chemical characteristics are the key uranium prospecting parts.
