Thickness of Jurassic-Cretaceous sequence in the Carpentaria and Laura basins

Brief description

Thickness of the basal Jurassic-Cretaceous sandstone aquifers in the Carpentaria and Laura basins. 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 2.12 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.

Statement: Thickness of the basal Jurassic-Cretaceous sandstone aquifer in the Carpentaria and Laura basins interpolated from point thickness values calculated from a variety of sources which include drill hole and seismic data. Seismic interpretation came from McConachie et.al. (1997). Stratigraphic information came from company well completion reports and BMR and GSQ stratigraphic drilling (references below). METHOD: Data was imported into ArcGIS as point sets. The isopach value field was used to interpolate a surface using the Topo to Raster tool in the Spatial analyst toolset. Isopachs were generated from the raster using the Contour tool in the 3d analyst toolset in ArcGIS. BOUNDARY The raster and isopachs were clipped to a boundary created from : 1.
