蒙古国铀矿地质特征及资源潜力

蒙古国蕴含较丰富的铀矿资源。本文总结了蒙古国74处已知的铀矿床（点）地质资料，将蒙古国铀矿划分为砂岩型、火山岩型、花岗岩型、蚀变岩型、沉积岩型等5种类型，其中火山岩型和砂岩型是蒙古国主要的铀矿矿床类型；通过对蒙古国大地构造背景及典型铀矿床地质特征进行研究，将蒙古国划分为4个铀成矿省，其中最具成矿潜力的是蒙古-额尔古纳铀成矿省、戈壁-塔木察格铀成矿省；结合蒙古国成矿地质背景及矿产开发情况，圈定了多尔诺特铀矿潜力区、乔伊尔铀矿潜力区、赛因山达-宗巴音铀矿潜力区、楚鲁特铀矿潜力区、布图里诺儿铀矿潜力区等5处铀矿勘查开发潜力区。

Geological features and resource potential of uranium deposits in Mongolia

Mongolia hosts rich uranium resources. This paper summarizes the geological data of 74 known uranium deposits (spots) in Mongolia and divides them into five types: sandstone, volcanic rock, granite, altered rock, and sedimentary rock types, among which the volcanic and sandstone types are dominant. Based on the study of the tectonic setting of Mongolia and the geological characteristics of typical uranium deposits, Mongolia can be divided into four uranium mineralization provinces. Among them, Mongolian-Erguna and Gobi-Talmaga provinces have the largest mineralization potential. Combined with the metallogenic background and mineral development of the country, this paper delineates five potential areas for uranium exploration and development, which are Dornod, Choyr, Sainshand-Zongbayin, Chuluth and Buturino.
