An interpretation of Eocene coastal sediment layer for outcrops or subcrops of Eocene coastal sediments in the northern Eucla Basin. Those sediments and related coastal depositional systems were interpreted from NOAA and ASTER Night-time Thermal images; palaeovalleys, Landsat, drillholes, mapped Basin and Province datasets; deposits 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: 
      Eocene coastal sediments were interpreted from the outcrops and subcrops in the northern Eucla Basin, developed concurrently.
      Polygons modified and extended on desktop GIS into interpreted areas using geological data and interpretations from Landsat MSS, NOAA, ASTER, 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.
