前言世界铀储量的大部分赋存在砾岩、砂岩和与古地表有关的脉型矿床中。然而,具有经济意义的重大富集也产在“非传统”矿床中。本文讨论的就是成因上与发生在地壳较浅部位的火成活动有关的铀矿化。在这些环境中形成的铀的富集规模很可能不大。但是,有时也能发展成经济上有吸引力的矿床。我们提出一种成因模式,并从几个方面 Foreword Much of the world’s uranium reserves are found in conglomerates, sandstones and vein-type deposits associated with paleocontinental landforms. However, significant enrichments that are economically significant are also produced in “non-traditional” deposits. This article deals with uranium mineralization that is genetically related to the volcanic activity occurring in the shallower crust. The scale of enrichment of uranium formed in these environments is unlikely to be large. However, it can sometimes develop into an economically attractive deposit. We propose a pattern of causes, and from several aspects
