| 摘 要： | 浙赣火山岩分布广泛并且产有重要的火山岩型铀矿床(赣杭构造带发育有五十一个火山岩型铀矿床)。通过对浙赣中生代火山岩相的划分及其特征的描述，划分出与其相对应的火山岩型铀矿床类型，即潜火山相对应于次火山岩型铀矿床、火山通道相对应于火山角砾岩筒型铀矿床、火山侵出相及火山喷发相之喷溢亚相对应于火山熔岩型铀矿床、火山喷发相之爆发亚相对应于火山碎屑岩型铀矿床、喷发沉积相对应于沉积火山碎屑岩型铀矿床。说明火山岩相与铀矿类型之间存在某种联系，研究火山岩相与其相对应的铀矿床对寻找火山岩型铀矿床有一定的指导意义。

| Abstract: | The volcanic rock distributes extensively and there are vital uranium deposits of volcanite type occurs in the Gan-Hang tectonic belts .There are 51 uranium deposits of volcanite type occurring in the Gan-Hang tectonic belts. This paper classified Mesozoic volcanic rock facies in Zhegan,explicits their characteristics ,then divides relevently subvolcanic facies to the uranium deposits of subvolcanic rock type, volcanic conduit facies to the uranium deposits of volcanic breccia chimney type,volcanic intrusion facies and extrusion subfacies of volcanic extrusion facies to the uranium deposits of volcanic lava type,explosive subfacies of volcanic extrusion facies to the uranium deposits of volcaniclastic rock type,extrusion-sedimentary facies to the uranium deposits of sedimentary volcaniclastic rock type.This paper announces the study of relationship of volcanic facies and uranium deposit types and the study of volcanic facies and its corresponding uranium deposits ,have great importance for the guide in prospecting and exploration of volcanite type uranium deposits. |
