摘要
根据铀的地球化学持点,本文确定了铀迁移的有利环境和铀从天然水中富集沉淀的天然条件,并划分了形成外生铀富集的不同的地球化学栅。在此基础上作出了铀的外生富集分类。既分出了现有的工业矿床,同时也推测了可望发现的矿床。本分类可作为预测新的铀矿成因类型的工具。
On the basis of geochemical characteristics of uranium, the favourable environments of uranium migration and conditions for the concentration and precipitation of uranium from natural water are determined and different geochemical barriers in the formation of exogenetic uranium concentration are distinguished in this paper. On this basis, the classification of exogenetic uranium concentration has been made. According to the classification based on the kinds of geochemical barriers for exgeneous water, not only the present economic deposits are classified, but also the deposits expected to be discovered are speculated. The classification can be used as a new tool for nredieting new genetic, tvnes of uranium denosits
