内蒙古介拉斯台盆地铀成矿条件分析与找矿预测

介拉斯台盆地处于扎兰屯火山岩型铀成矿远景带中段,是国内中生代火山岩最为发育地区之一,多期次断裂、火山活动强烈发育,铀成矿地质背景优越。文章通过对介拉斯台中生代火山岩盆地的大地构造背景、基底和盖层的含铀性、潜火山岩、断裂、火山机构、热液蚀变、铀矿化等铀成矿地质条件研究,并结合航放、化探及遥感找矿信息进行综合分析,认为介拉斯台中生代火山岩盆地具有较好的铀成矿潜力,圈定成矿远景区5处。

Analysis of uranium metallogenic conditions and prospecting prediction in Jielasitai basin, Inner Mongolia

Jielasitai basin is located in the middle part of Zhalantun volcanic rock type uranium metallogenic prospect belt. It is one of the areas where the Mesozoic volcanic rocks mostly developed in China and multi-stage faults developed with strong volcanism and superior uranium metallogenic condition. Based on the analysis of the geogeotectonic background, uranium-bearing property of the basement and cover, subvolcanic rock, fault, volcanic apparatus, hydrothermal alteration, uranium mineralization, etc., are comprehensively analyzed. In combination with the information of aerial radioactive measurement, geochemical exploration and remote sensing prospecting. It is considered that the Jielasitai basin is potential for uranium prospecting, and five metallogenic targets are delineated.
