Palaeodrainage and Cenozoic coastal barriers of South Australia - revised map and GIS dataset

A second edition of the map and an associated GIS data package (ArcGIS and MapInfo formats) are now available.

Changes include:

  • revised sediment boundaries based on newly acquired datasets (e.g. ASTER night-time thermal satellite imagery and airborne electromagnetic (AEM) surveys)
  • a modified approach to paleodrainage mapping following industry feedback
  • new data from recent mineral exploration activity
  • geological sections to illustrate sediment and bedrock relationships.

Additional information in the GIS data package includes links to biostratigraphic data and key reference drillholes.

All polygons now include metadata that identifies the primary data sources used in the mapping process and the level of confidence in the interpretation.

The revised map takes into account new data and interpretations arising from regional surveys and exploration activities in South Australia, particularly for uranium, heavy mineral sands and groundwater associated with palaeodrainage and coastal sediments.
