An interpretation of Palaeogene palaeodrainage for South Australian Tertiary palaeodrainage systems, which are marked by Palaeogene fluvial sediments. Those sediments and channel systems were interpreted from NOAA and ASTER Night-time Thermal images; Airborne Electromagnetic data; palaeovalleys, palynology, Company Reports, mapped Basin and Province datasets; drillhole data and geological mapping.The major use is in mineral exploration of palaeochannel deposits but contributes also to basic geological understanding of South Australian palaeodrainage systems, in conjunction with companion data of State geological map.

      Source data: 
      Palaeogene palaeochannels interpreted from the outcrops or drillcores within the palaeodrainage systems of South Australia, developed concurrently.
      Polygons modified and extended on desktop GIS into interpreted areas using geological data and interpretations from AEM data, NOAA, ASTER, SA Geology (100k), SA Basins and Provinces, drillhole data and geological mapping.
      Accuracy variable, dependent in part on scale and quality of source data.
      As dataset is partly interpretive, positional accuracy and boundaries are subject to alternative interpretation.
      Geological attributes are based on interpretation of features in the subsurface which are not directly observable; thus they are subject to alternative interpretations.
