各种热液矿床(包括铀矿床)研究中重要的问题是:成矿溶液是怎样形成的,在成矿过程中是怎样演化的;在矿脉中沉淀的各种成矿元素又是从哪里来的。当然,可以有很多准则(地质、矿物、岩石化学与微量元素等)来判断成矿溶液的成因和成矿物质的来源,但目前的研究表明,同位素准则具有其它准则所不能比拟的优越性。因此,我们在对8411铀矿床开展常规的地质与地球化学研究的同时,也较为系统地进行了氧、硫、铅同位素研究工作。本
The important questions in the study of various hydrothermal deposits (including uranium deposits) are: how the ore-forming solution was formed and how it evolved during mineralization; and where are the various ore-forming elements precipitated in the veins of. Of course, there are many criteria (geology, minerals, petrochemistry and trace elements) that can be used to judge the origin of ore-forming solutions and the origin of metallogenic materials. However, current research shows that isotope criteria have the superiority unmatched by other standards. Therefore, while conducting conventional geochemical and geochemical studies on the 8411 uranium deposit, we conducted a relatively systematic study of oxygen, sulfur and lead isotopes. this
