The Different Characteristics and Geological Significance of Reduction Alteration of Sandstone-Type Uranium Deposits in Northwest Region of China

Based on isotope trace studies of sandstone-type uranium deposits in Dongsheng area of Ordos basin, south margin in Yili basin and Turpan-Hami basin, such as geological attitude, carbon and oxygen isotope in fluids, hydrogen and oxygen isotope, sulfur isotope in pyrite and carbon isotope in “detritus pot top gas” of mineral-bearing stratum, this paper reveals the different features of the reduction and alteration among the formation of three...
