摘要
512铀矿床层间氧化带水岩体系Eh 和 pH值的研究结果表明 ,层间氧化带内相同亚带的水岩体系Eh 和 pH平均值极为接近 ,而不同亚带的水岩体系Eh 值具有明显差异 ,即从氧化带到还原带 ,水岩体系Eh 值明显下降 ;层间氧化带内不同亚带的水岩体系 pH值也有所不同 ,氧化带和还原带处于弱碱性介质环境 ,而氧化还原过渡带则处于中性介质环境 ;水岩体系Eh 和 pH值可以作为划分层间氧化带和圈定铀矿体位置的依据。
Studies on the application of water-rock system E h and pH values to the interlayer oxidation zone of No.512 uranium deposit show that the water-rock system E h mean values are very close to each other in the same subzone of the interlayer oxidation zone, while the water-rock system E h values are obviously different in different subzones of the interlayer oxidation zone, i.e., from the oxidation zone to the reduction zone, the water-rock system E h values clearly decrease. The water-rock system pH values are somewhat different in different subzones of the interlayer oxidation zone, i.e., the oxidation and reduction zones are in an environment of weakly alkali media whereas the reduction-oxidation transitional zone is in the setting of neutral media. The water-rock system E h and pH values can be regarded as the evidence for dividing the interlayer oxidation zone and delineating the uranium orebodies.
