This inaugural regolith map of the southern Gawler Ranges margin provides a valuable regional overview of the main regolith types and their associated landforms, plus a general outline of the major areas of bedrock or regolith-dominated terrain, as well as spatial information about the occurrence of in-situ versus transported regolith. A major challenge that bedrock mineral explorers face in many parts of South Australia is how to explore efficiently and effectively through extensive and thick regolith cover. The new regolith map aims to provide a broad-scale framework for guiding geochemical prospecting for a wide range of minerals and materials, thereby serving to enhance the value of resulting mineral exploration data, and is also intended to provide a useful dataset for addressing other land use issues like groundwater assessment and management.
