Mineral exploration in the northern Curnamona Province is made difficult by a cover of weathered Cainozoic sediments up to 200 m or more thick, overlying weathered Proterozoic bedrock of the Broken Hill and Olary Domains. Four projects have been initiated by the Cooperative Research Centre for Landscape Evolution and Mineral Exploration (CRC LEME) to address issues of landscape evolution, geochemical anomaly recognition, and mechanical and hydromorphic dispersion in the southern Callabonna Sub-basin overlying the Curnamona Province. The research reported here provides the basis for a holistic investigation of mechanical and hydromorphic geochemical dispersion pathways within the regolith and sedimentary cover of the basin, to aid the detection of mineralisation under deep cover.
