| 摘 要： | 512铀矿床不同氧化还原环境水岩体系Eh和pH值的研究结果表明：同一氧化还原环境的水岩体系Eh平均值极为接近；不同氧化还原环境的水岩体系Eh值差异明显，即从氧化带到还原带，水岩体系Eh值明显下降；不同氧化还原环境，其水岩体系pH值也有所不同，氧化带和还原带处于弱碱性介质环境，过渡带（矿化地段）处于中性介质环境；水岩体系Eh和pH值可以作为划分含矿层氧化还原环境分带及圈定铀矿体位置的依据。

| Abstract: | Studies on the water\|rock system Eh and pH values to the different oxidation\|reduction settings in 512 uranium deposit show that, the water\|rock system Eh mean values are very near to the identical oxidation\|reduction settings. The water\|rock system Eh values are of obvious difference to the different oxidation\|reduction settings, that is, from the oxidation zone to the reduction zone, the water\|rock system Eh values clearly decrease. The water\|rock system pH values have some difference to the different oxidation\|reduction settings, that is, the oxidation and zones are in the weakly alkali medium settings and then the transition zone(mineralized sector) is in the neutrality medium settings. The water\|rock system Eh and pH values can be regarded as the evidences to divide the oxidation\|reduction settings zonality and outline the uranium orebody position. |
