| 摘 要： | 本文以层间氧化带型铀矿床为例，根据各层间分带中铀存在的形式和状态、铀成矿的条件及各阶段相应的化学变化及气体扩散所引起的氧浓度梯度变化，对砂岩型铀矿床上方氧的分布模式做了初步探讨。通过在已知矿床上取得良好效果的应用实例，指出野外工作时应注意的问题。认为该法在寻找可地浸砂岩型铀矿床中不失为一种简单易行的方法。

| Abstract: | Taking interlayered oxidation type uranium deposit as an example, this paper describes the existence forms and states of uranium in different of interlayered oxidation zones, urantum metallogenetic conditions, chetnical changes of uranium corresponding to various stages, as well as the gradient variation of oxygen concentration which results from gas diffusion in interlayered oxidation zone, and preliminarily discusses the distribution model of oxygen over sandstone-type uranium deposit. Through the successful application case history over a well-known uranium deposit, authors present some problems to which attention must be paid during field oxygen mesurement It is considered that the measurement of oxygen in soil is a simple and convenient technique for prospecting in-situ leachable sandstone-type uranium deposits. |
