东西伯利亚是俄罗斯联邦最大的铀矿省,包括近20个规模不同的和建造属性各异的铀矿区。本文刊出了4种主要矿床类型典型矿区的一些具体的成矿特点,主要是交代型和多成因-交代型多期的花岗岩化。主导活化构造的主要特点是:内部组构复杂;具明显的放射性地球化学专属性;有大规模成矿预富集的地质-构造环境。查明铀矿区形成的规律性,有利于更有根据地预测具高含铀性的新矿区。
East Siberia is the largest uranium province in the Russian Federation, including nearly 20 different size and construction properties of uranium deposits. This paper presents some specific metallogenic characteristics of the four main deposit types of typical mining areas, mainly the metasedimentary and multi-genesis-metasomatic granitization. The main features of the dominant activation structure are: the internal complex structure; obvious radioactive geochemical specificity; large-scale metallogenetic preconcentration of the geological - tectonic environment. Identifying the regularity of the formation of uranium deposits is helpful for more predictable new mining areas with high uranium content.
