摘　　要：内蒙古东沟营盆地位于扎兰屯铀成矿远景带北段,铀成矿地质条件优越.受林区覆盖厚、交通不便等因素制约,铀矿地质调查工作程度低,找矿进展缓慢.在区域铀成矿地质背景分析的基础上,通过对典型铀矿点控矿因素进行剖析,结合航空放射性、地球化学、遥感多源铀成矿信息,构建了火山岩型铀矿综合找矿模型.类比邻区典型火山岩型铀矿床,开展找矿远景分析,认为研究区具备较好的找矿前景.依据找矿模型,结合地质、物化遥综合找矿信息,圈定铀成矿有利区段4处.其中新圈定成矿有利区段3处,其成矿地质条件优越,找矿线索丰富,找矿前景较好.Donggouying basin is located in the north section of Zhalantun uranium metallogenic prospective belt,with superior mineralizing geological conditions.Due to the thick forest coverage and poor transportation,the degree of uranium geological survey is low and prospecting progress is slow.Based on the regional uranium mineralization geological background,by analyzing the ore-controlling factors of typical uranium occurrences,combined with the multi-source information of airborne radioactivity,geochemistry and remote sensing,the paper constructs the integrated prospecting model for volcanic-type uranium deposits.Compared with the typical volcanic-type uranium deposits in adjacent areas,the prospect analysis concludes that the study area has a good prospecting potential.According to the prospecting model,combined with the geological,physical-chemical-remote sensing integrated prospecting information,4 favorable areas for uranium mineralization are delineated,among which 3 are newly-delineated,with superior metallogenic conditions,abundant prospecting clues and good prospecting potential.
