本文介绍了在额尔古纳超大型火山热液型铀成矿带中发现的超大型火山热液脉型铀矿床有５个，大型火山热液脉型铀矿床有６个，总共有铀金属储量３３万ｔ，在世界热液脉型铀矿资源量中占有重要地位。经研究认为，该成矿带内铀矿床成矿作用在时间上具有突发性特征，成矿时代集中在早白垩世，受统一中生代大陆裂陷－火山岩浆活动控制；成矿介质为深源的火山岩浆水、大气水和变质水三者相混合的具中低温的火山热液，成矿物质主要来自中生代深部富集型的岩浆源
This article describes five large volcanic hydrothermal vein type uranium deposits found in the Ergun supervolcanic hydrothermal uranium metallogenic belt, six large volcanic hydrothermal vein type uranium deposits, and a total of uranium metal Reserves 330,000 t, in the world hydrothermal vein uranium resources occupy an important position. According to the study, the metallogenetic characteristics of uranium deposits in this metallogenic belt are characterized by a sudden change in time. The metallogenetic age is concentrated in the Early Cretaceous and controlled by a unified Mesozoic continental rift-volcanic magmatic activity. The metallogenic medium is deep-sourced Of volcanic magma water, atmospheric water and metamorphic water are mixed with low and medium temperature volcanic hydrothermal fluids. The ore-forming materials mainly come from the deep Mesozoic magma source
