该文以伊犁盆地南缘乌库尔其地区各矿床为研究对象 ,阐述了层间氧化带砂岩型铀矿床层间铀成矿过程中的流体作用及伊犁盆地流体演化史对砂岩型铀成矿的控制等。试图通过稳定同位素、稀土元素等示踪方法研究该地区层间流体的来源、运移及向成矿流体的演化并成矿的流体作用机制 ,认为 V22 旋回层间流体主要来自受大气水补给的基岩裂隙水 ,并且在层间流体流向上全岩氧同位素组成存在明显的变化规律
In this paper, the ore deposits in the Wuqurqi area in the southern margin of the Ili basin are studied, and the fluid effects during interlayer uranium metallogenesis in interlayer oxidation zone sandstone-type uranium deposits and the fluid evolution history of sandstone-type uranium mineralization Control and so on. Attempting to study the source, migration and evolution of ore-forming fluid and the fluid mechanism of ore-forming fluid in this area by means of tracer methods such as stable isotopes and rare earth elements, it is considered that the fluid between V22 cycles mainly comes from the recharge of atmospheric water Bedrock fissure water, and there is a clear change rule of the isotopic compositions of the whole rock in the interlayer fluid flow
