| A Study of the Formation Process and Ore-Prospecting Indicators of the Sandstone Type Uranium Deposits in the Light of Uranium Series Isotopes |
| Based on a study of uranium series isotopes in uranium-bearing strata from different sectors of the No. 512 deposits, this paper deals with the formation process of sandstone type uranium deposits. According to distribution regularities of the compositions of uranium series isotopes in front of the ore roll and characteristics of isotope samples from different oxidation-reduction zones, the authors hold that the distribution of uranium series isotopes can not only be used to predict the location of the uranium ore body, but also be employed to study rolling mineralization of the roll in the process of the ore body formation. It is proper to name region A as the region of redox contradiction. |
