Abstract

Tectonism is believed to have exerted a strong control on the current disposition of sedimentary hosted uranium mineral deposits in the Frome Embayment, in South Australia. However the extent of this control has not been well understood, nor documented. Here, we examine the combined use of regional and finer-scale TEMPEST AEM data sets, linked to a structural interpretation of airborne magnetics and ground gravity, to extend our understanding of the evolution, geometry and variability of sediment packages associated with sedimentary uranium mineralisation in the Curnamona and Billeroo Palaeochannel systems. Through the analysis of both smooth and blocky model LEI inversions of these AEM data, we contend that structural control was critical in determining the initial orientation of the palaeovalleys and the location of basal sequences of the Eyre Formation, the host to known uranium mineralisation. We examine this influence in the context of the Goulds Dam uranium deposit. The presence of reactivated basement faults which controlled the initial orientation of the palaeovalley systems may also have a role in providing the loci for mobile reductants from underlying basin sequences, although this requires further investigation.
