Base Great Artesian Basin hydrogeological units in contact with Basement

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

Polygons representing a regional interpretation of the of the Jurassic-Cretaceous stratigraphic units at the base of the GAB, as hydrostratigraphic units. To be used in conjunction with dataset 'Hydrogeological basement units in contact with the base of the Great Artesian Basin' (Geoscience Australia dataset, Catalogue #75910) to represent areas of potential hydraulic interconnection between the Great Artesian Basin and basement hydrogeological units.

Data is available in Shapefile format. This GIS data set was produced for the Great Artesian Basin Water Resource Assessment and used in: Figure 5.8 of Ransley TR and Smerdon BD (eds) (2012)

Dataset History

This dataset is a regional interpretation based on drill-hole lithological data to assign hydrogeological character of base GAB units. It is used in conjunction with the dataset 'Hydrogeological basement units in contact with the base of the Great Artesian Basin' (Geoscience Australia dataset, Catalogue #75910) to identify potential hydraulic interconnection between the Great Artesian Basin and basement units.

METHODS:

Stratigraphic point control was provided by borehole lithostratigraphic picks from QPED (Geological Survey of Queensland, 2010), PIRSA (2007), GABLOG (Habermehl 2001), as well as lithostratigraphic picks for the Clarence-Moreton Basin by Phil O'Brien (2011). Where there was a paucity of well data available, the interpreted lithostratigraphy was taken from the following sources:

Carpentaria Basin offshore: McConachie et al. (1997)

Carpentaria Basin onshore: Mapping by Smart et al. (1980).

Coonamble Embayment: 1:250 000 scale geological map series (Geoscience Australia 2010) for eastern margin; Kellett pers. comm. for the western margin

Poolowanna Trough: Cotton et al., (2006)

Hand drawn transparency interpretations were scanned. Scanned images were rectified within ArcGIS and vectorised into linework using the ArcScan toolset. Polygons were then generated from the vectorised linework and were attributed with a code name within the field "Hydro_code". This field was used to symbolise the dataset.
