dc.description.abstractThis volume contains a description of the distribution of minerals and elements at Koongarra, including the distribution of radionuclides. The Koongarra orebody is situated 225 km east of Darwin in the Northern Territory of Australia. The zone of primary uranium mineralisation has been intersected by weathering conditions, and this has resulted in the formation of a secondary ore zone and dispersion fan in the weathered zone. The uranium distribution over the site was investigated to determine the extent and direction of uranium migration from the primary uranium mineralisation. The depth patterns of uranium concentration were also investigated to elucidate depths. The distribution of elements, rock and minerals, and how they may affect uranium mobility, or indicate interactions between uranium and solid phases, were considered. Multi-elemental analyses were carried out on many samples to provide basic concentration data about various geochemically significant elements, and to elucidate how the elements interact with one another, the solid substrate and the groundwater. This included the analysis of bulk rock samples, visually distinct sub-samples, different particle sizes and chemically defined phases. Similarly, mineralogical data supplied information on the substrate reacting with the groundwater. Extensive studies were undertaken to elucidate the form of uranium in the weathered zones. These involved optical and electron microscopy studies and auto-radiography. Spatial trends of uranium series disequilibria in bulk rock, secondary uranium minerals and different chemically defined phases were analysed. These give information about uranium deposition and leaching, the evolution of the dispersion fan, the roles and relative importance of different mineralogical phases and processes involved in the retardation of radionuclides.en_AU
