层间氧化带砂岩型铀矿中铼的地球化学行为及找矿意义探讨

铼是地壳中一种极度分散的元素。在层间氧化带边界上 ,铼与铀的沉淀条件近似 ,在铼富集的层间氧化带砂岩型铀矿床中 ,铼富集的范围几乎与铀矿卷重叠。本文根据自然界已查证的层间氧化带砂岩型铀矿中铼、铀同消长的基本事实 ,对现阶段铼在层间氧化带砂岩型铀矿勘查中的找矿意义提出质疑。

Geochemical behavior of rhenium at interlayer oxidation zone sandstone-type uranium deposits and discussion on its prospecting significance

Rhenium is an element which is extremely dispersed in earth crust.At the redox front of interlayer oxidation zone,rhenium is precipitated as uranium is.So,at interlayer oxidation sandstone type uranium deposit the area of rhenium concentration is approximately in coincidence with that of uranium roll.Based on the basic fact verified in the nature that in different geochemical zones of interlayer oxidation zone sandstone type uranium deposit,uranium and rhenium contents synchronously increase and decrease.The author of this paper proposes doubts about the prospecting significance of rhenium for locating interlayer oxidation zone sandstone type uranium deposit.
