Evidence of uranium biomineralization in sandstone-hosted roll-front uranium deposits, northwestern China
We show evidence that the primary uranium minerals, uraninite and coffinite, from high-grade ore samples (U3O8N0.3%) in the Wuyiyi, Wuyier, and Wuyisan sandstone-hosted roll-front uranium deposits, Xinjiang, northwestern China were biogenically precipitated and psuedomorphically replace fungi and bacteria. Uranium (VI), which was the sole electron acceptor, was likely to have been enzymically r...
متن کاملThe Utility of Hyperspectral Data on Exploration of Sandstone-hosted Uranium Deposits
Based on hyperspectral data mining techniques and characteristics of imaging spectrum, Hyperion satellite hyperspectral data are used to study the diagnosable spectral signatures and quantitatively extract the absorption spectral features of sandstone-hosted uranium deposits in northern China. In terms of information extraction approach and the processing method of extra-abundance data, we have...

متن کاملMineral paragenesis and textures associated with sandstone-hosted roll-front uranium deposits, NW China
We present a first paragenetic study of the Wuyier, Wuyisan, Wuyiyi and Shihongtan sandstone-hosted roll-front uranium deposits, northwest China. The mineralization is hosted by Lower–Middle Jurassic coarseto medium-grained sandstones, which are dark-gray to black due to a mixture of ore minerals and carbonaceous debris. The sandstone is alluvial fan-braided river facies. Minerals associated wi...
