根据不同世代铀矿物共生组合的成分、形成顺序和空间分布等资料可以在一系列情况下探讨成矿的化学作用,特别是氧化还原条件的变化,虽然类似的探讨只是定性的,但可帮助了解各种铀矿物分布的规律性,这对于矿床的工业评价是重要的。通过三个矿田矿物组合的研究实例我们试图阐明铀矿物类型及其形成对氧化还原条件之间的关系。在第一号矿田,典型的脉状矿床赋存于变质粉砂岩中,铀矿脉主要由碳酸盐和少量其它矿物组成,后者中分布最广的是铅、锌、、铁的硫化物和沥青铀矿,脉形成于四个阶
According to the composition, formation order and spatial distribution of the symbiotic assemblages of uranium minerals from different generations, the chemical effects of mineralization, especially the redox conditions, can be explored in a series of cases. Although similar discussions are only qualitative, they can help to understand The regularity of the distribution of various uranium minerals is important for the industrial evaluation of the deposit. Through the case study of three orefield mineral assemblages, we attempt to elucidate the relationship between uranium mineral types and their formation and redox conditions. In the No. 1 ore field, typical vein-like deposits occur in the metamorphic siltstone. The uranium veins are mainly composed of carbonate and a small amount of other minerals. Among the latter, the most widely distributed ones are lead, zinc and iron sulfide And pitch uranium, vein formed in four steps
