Abstract

Thickness of Cenozoic weathering in the Great Artesian Basin. Data is available as isopachs and raster. Isopachs are in Shapefile format. Rasters are in both ESRI grid and ASCII grid formats. This GIS data set was produced for the Great Artesian Basin Water Resource Assessment and used in Figure 3.3 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin. A technical report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment. CSIRO Water for a Healthy Country Flagship, Australia. This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 76539.

For Central Eromanga Basin, Carpentaria Basin, Laura Basin and Surat Basin, weathering depth were derived from reports contained in descriptive lithological logs from Well Completion Reports. Weathering thicknesses were derived from the QPED stratigraphic database where the logged information reported the alluvium and weathering thickness. Thickness data were imported into ArcGIS as point sets and interpolated to create a surface using the Topo to Raster tool in the ArcGIS Spatial analyst toolset. The raster was clipped to the Great Artesian Basin Water Resource Assessment project boundary - offshore included (Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin. A technical report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment. CSIRO Water for a Healthy Country Flagship, Australia). Isopachs were generated from the raster, using the Contour tool in the 3d analyst toolset in ArcGIS.
