The research project's aims were : 1. to apply thermoluminescence (TL) methods to the uraniferous Narlaby Palaeochannel 2. to study the granite palaeochannel basement as a possible source of uranium. Artificial TL applied to 162 samples revealed that all Narlaby channel sediments in the study area have suffered major radiation damage due to the passage of at least 10 ppm U concentrations. The underlying palaeochannel basement shows 2 distinct TL glow curves: (1) radiogenic type, and (2) early Proterozoic type. Microscope studies and these TL results indicate that the Eocene channel fill is derived from the uranium-rich Hiltaba Granite, thus receiving high inherent radiation damage as well as further quartz crystal damage caused by later radionuclide releases from the likely uranium source. A genetic model where mineralization is a result of multi-stage U enrichment is proposed.
