Hydrogeological basement units in contact with the base of the Great Artesian Basin  

Authors / CoAuthors

Abstract

Polygons representing a regional interpretation of basement stratigraphic units as hydrostratigraphic units, in contact with the base of the Jurassic-Cretaceous sequence of the GAB. To be used in conjunction with dataset 'Base Great Artesian Basin hydrogeological units in contact with basement' (Geoscience Australia dataset, 2013, Catalogue # 75911) to represent areas of potential hydraulic interconnection between the Great Artesian Basin and basement 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) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.

This dataset is a regional interpretation based on drill hole lithological data to assign hydrogeological character of basement units. It is used in conjunction with the dataset 'Base Great Artesian Basin hydrogeological units in contact with basement' (Geoscience Australia dataset, 2013, Catalogue # 75911) to identify potential hydraulic interconnection between the Great Artesian Basin and basement units.

Canberra, Bureau of Mineral Resources, Geology and Geophysics. 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.
