| Application of the Water-Rock System Eh-Ph Method to the Division of the Interlayer Oxidation Zone in the Sandstone Type Uranium Ore: Exemplified by No.512 Uranium Deposit, Yili Basin, Xinjiang |
| 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. |
