摘要
从区域环境到矿化阶段的系统论述,其用意是强调区域环境的深部构造热作用是成矿的热动力基础,多种地球物理-地球化学场(晕)叠置区是成矿区的标志。火山-岩浆演化是热源的积累,先钼后铀的矿化作用基础,碱性流体交代蚀变和氢交代铀富集成矿等综合因素决定了居隆庵是一个具有较大潜力的铀资源地段。
The paper is a systematic exposition from regional environment to mineralizing stages, the purpose is to emphasize that deep structural thermal events are the thermodynamic basis and superposed areas of all kinds of physiochemical field （halo） are the indicator of ore-forming area. Volcano-magma evolution is the accumulation of thermal activities. Uranium enrichment caused comprehensive factors such as metasomatic alteration of alkaline-acid fluid, hydrogen metasomatism make Julong＇an a uranium resources segment which has a greater potential for uranium mineralization.
