| 摘 要： | 若尔盖轴矿床位于西秦岭铀成矿带下志留统硅岩和灰岩建造中，在分析不同类型地层、岩石、矿石及矿物中的碳、硫、铅及氢氧稳定同位素组成的基础上，探讨成矿物质及成矿介质溶液的来源。研究表明成矿物质来源于地层及深部，成矿水溶液具岩浆水及深循环水混合特点，且成矿期含矿热液在围岩地层中又发生过叠加富集作用。

| Abstract: | Ruoergai uranium occurred located in silicolites and limestone of Lower Silurian in uranium metallogenic belt of Western Qinglin.The carbon,sulfur,lead,hydrogen and oxygen stable isotope compositions from ores,minerals and rocks of different strata were analysed in this paper.The results showed that the ore forming elements were mainly originated from strata and deep sources and that ore bearing solution was mixed product of magmatic water and deep circulating ground water.Superposed enrichment of ore solution took place in silicolites and limestones of strata during the mineralization. |
