Layer 02 Great Artesian Basin base of Cenozoic surface  (GABWRA)

## **Abstract** 

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. The metadata was not provided by the data supplier and has been compiled by the programme based on known details.



Surface produced for the Great Artesian Water Resource Assessment (GABWRA) by Geoscience Australia (http://www.ga.gov.au). This surface was created for 3D visualisation of the Base of Cenozoic sequence. It was used in Figure 3.1 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.



The surface is available in the following formats

1. GOCAD surface  (.ts)

2. ESRI grid

3. ASCII grid (.grd)



Use limitations: 

1. GOCAD surface requires program capable of reading GOCAD \*.ts (triangulated surface) files

2. ASCII grid data requires re-interpolation by end-user resulting in minor differences to accompanying GOCAD \*.ts surface

## **Dataset History** 

SOURCE DATA: 



For the Karumba and Kalpowar basins, seismic interpretation used information sourced McConachie et al (1997). Stratigraphic well picks from company well-completion reports for exploration drilling in the region - available from the QDEX database (Queensland Department of Natural Resources and Mines, 2012), Blake et al (1984) and BMR stratigraphic drilling reports (Gibson et.al., 1974).



Stratigraphic drill-hole data on the Eromanga Basin came from PEPS-SA (South Australian Department for Manufacturing, Innovation, Trade, Resources & Energy, 2011) and the QPED database (Geological Survey of Queensland, 2010). Data sourced from contours and maps in Moussavi-Harami & Alexander (1998), Kellett et al (2004, 2008), Senior (1968) and Langford et al (1995). Digital thickness data was sourced from the Office of Water, Dubbo, NSW (Sue Hamilton, Pers. Comm., 2012). Contours for thicknesses in the Kingoonya Paleochannel were sourced from Hou et al (2007)



BOUNDARIES: 



The surface was clipped to the Assessment boundary (Ransley & Smerdon (Eds.) 2012).
