Datasets

The mesac Open Data Portal datasets contain detailed records of seismic surveys and geochemical data, and they are made available here to industry, researchers and the public.

  • Regolith - RED Scheme, Southern Gawler Ranges Margin (YARDEA and PORT AUGUSTA 1:250 000 map sheets)

    The regolith map of the Southern Gawler Ranges Margin geoscience product provides a valuable regional overview of the main regolith types and their associated landforms, a general outline of the major areas of bedrock or regolith dominated terrain, as...

  • Regolith - RED Scheme, South Australia

    The Regolith detail geoscience product provides basic information about the major regolith materials and landforms. Eleven attributes have been assigned to each regolith polygon allowing the creation of four individual map products: regolith...
