The Nabarlek uranium deposit, Northern Territory, Australia; some petrologic and geochemical constraints on genesis

Abstract

Deposit is confined to a shear zone in contorted and metasomatized early Proterozoic schists. Occurs near an unconformity. Massive chlorite-sericite-hematite rocks. Uraninite intergrown with chlorite. Sericitization, redox reactions. Th ratios suggest transport as a uranyl complex. Isotopic data on minor carbonate suggest organic material was originally associated with the mineralization and indicate that these carbonates have evolved from the interaction of hydrothermal fluids with this material. Erosion has exposed the deposit to the effects of weathering.--Modified journal abstract.
