With the dawning of renewed interest in one of South Australia’s historic gold provinces, driven by the newly acquired data from the Department’s highly successful Gawler Craton Airborne Survey (GCAS), the Geological Survey of South Australia has teamed up with researchers from CSIRO to generate new ideas for tackling the challenge of exploring through the cover of the greater Tarcoola area. Part of this project has included undertaking the compilation of a regolith material and landform map. A variety of regolith mapping data is already available for the central Gawler Craton, but the records vary in scale, detail and consistency. Existing regolith map data for the greater Tarcoola area include GSSA’s state-wide regolith layer, plus the four regolith maps of Bon Bon-Eba, Half Moon Lake, Edoldeh Tank and Tunkillia compiled as part of the Cooperative Research Centre for Landscape Environments and Mineral Exploration (CRC LEME) work done in the early 2000s. The subject newly compiled regolith map for the greater Tarcoola area covers the Malbooma, Tarcoola and Kingoonya 1:100,000 scale mapsheet areas. Mapping was based on the 1:100,000 State geology dataset and used the RTMAP (regolith landform mapping) scheme devised by Pain et al. (2007). The precision of mapping was improved by the use of remote sensing data (including new Landsat 8 imagery) as well as high resolution digital elevation and radiometric data from the GCAS Regions 9A and 9B coverage. In addition, one field trip made to the study area provided vital on-ground observations. This resulted in the definition of 22 regolith landform units, with the map legend giving information about regolith materials and landform defining each of these units. Because mineralisation in regolith is often related to intense induration, e.g. uranium and gold in calcretes, induration of regolith materials was also mapped. Calcrete, silcrete and ferricrete have been included as three separate induration/duricrust units. The polygon line work for the regolith map was compiled using ArcGIS 10.6. For each regolith polygon, twelve attributes were captured during the mapping process, including regolith materials and landform name, description, RTMAP code and map symbol, as well as the TI (transported vs. in-situ) and RED (residual-erosional-depositional) schemas, which are based on previous regolith mapping undertaken by GSSA. It should be noted that the subject map represents merely the surface distribution and physical expression of regolith units; it does not include any information about their thickness, and gives only limited, relative conclusions about their stratigraphy and age. Outcropping bedrock has been assigned to map units on the basis of its geological province, lithology, stratigraphy and/or age. Scant information about bedrock weathering intensity was available from existing datasets.
