安庆大龙山铀矿床铀成矿地质特征浅析

A brief analysis of geological features of the Dalongshan uranium ore deposit formation in Anqing

从铀矿化与地层岩性、岩浆岩、构造、围岩蚀变的关系及铀矿体分布规律、矿石特征、矿化阶段等方面,阐述了安庆大龙山铀矿床铀成矿地质特征。认为该铀矿床具有品位高,埋藏浅,易采易冶的特点,其铀矿化受岩性、构造、岩体接触带、热液蚀变等联合控制,为中低温热液脉状充填型铀矿床。

This paper discussed geological features of the Dalongshan uranium ore deposit formation in Anqing in view of relations of uranium mineralization with stratum lithology, magmatic rocks, structures and wall rock alteration as well as distribution law of uranium ore bodies. It is suggested that the uranium ore deposit is high in grade, buried shallowly and easy to mine and smell, and the uranium mineralization is jointly controlled by lithology, structure, rockmass contact and hydrothermal alteration, belonging to medium-low-temperature hydrothermal vein filling-type deposit.
