SOURCE DATA:

Stratigraphic point control was provided by borehole stratigraphic picks from QPED (Geological Survey of Queensland, 2010), PIRSA (PIRSA, 2007), GABLOG (Habermehl, 2001), as well as picks by Phil O'Brien (2011) for the Clarence-Moreton Basin. These were used to constrain the existing Senior basement surface (Senior and associates, 1997), extended primarily on seismic interpretation. Because the Senior basement surface included Triassic sequences in the Surat and Eastern Eromanga basins, based on the then-existing Habermehl definition of the GAB, in areas overlying the Galilee and Bowen Basins, the Senior basement surface was replaced by the Senior Top- Moolayember surface (Senior and associates, 1997). With these adjustments, the modified Senior basement surface was accepted for the onshore GAB in Qld and NT. For South Australia, the PIRSA/ Water Commission interpreted surface (PIRSA, 2007) was used as this included latest seismic survey data. In the Carpentaria Basin, for the offshore region, the basement surface was compiled from McConachie & Stainton (1994). McConachie et.al. (1997) was used for the onshore region of the Carpentaria Basin. For the eastern Coonamble Embayment, contour data of Hawke and Cramsie (1989) was used. Elsewhere in NSW to the west, the stratigraphy data of Hinds (2011) was applied.

BOUNDARIES:

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