摘要]安徽庐枞火山盆地位于长江中下游成矿带中段,燕山期强烈的构造一岩浆活动孕育了盆地
内铀成矿作用。在整理前人勘查及研究成果基础上,对铀矿地质特征进行了分析,总结了成矿控制因
素。庐枞火山盆地铀矿与潜火山岩具密切时空和成因关联,铀成矿受潜火山岩、构造及地层岩性综合
控制,但潜火山岩浆侵入作用是成矿关锥因素。后续铀矿找矿工作,在对潜火山岩体外围有利空间勘
査的同时,尤其要加强寻找与隐伏岩体有关的隐伏矿体,以实现铀资源扩大的预期。

Abstract: Luzong volcanic basin in Anhui is located in the middle of Middle-lower Yangtze River
metallogenic belt. Strong Yanshanian tectonic-magmatic activity breeded the uranium mineralization in
the basin. Based on reorganizing the previous exploration and research results, this paper analyzed
the geological characteristics of the uranium deposits and summarized the metallogenetic factors
Uranium deposits in Luzong volcanic basin are associated with subvolcanic rock in time, space and
genesis. Although the uranium mineralization is controlled by the subvolcanic rocks, tectonics and
ormation lithology, the intrusion of subvolcanic magma is the key factor of mineralization. In order
to realize the expectation of enlarging the uranium resources, the subsequent uranium prospecting
work should explore the advantageous outside space of the subvolcanic rock mass, especially find the
concealed uranium ore body which is connected with th
ne concealed rock mass.
Key words subvolcanic rock; geological characteristics of uranium deposits; metallogenetic factors;
