Layer 05 Base of Hooray Sandstone and equivalents surface
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 Hooray Sandstone and Equivalents.
The surface is available in the following formats
GOCAD surface (.ts)
ASCII grid (.grd)
GOCAD surface requires program capable of reading GOCAD *.ts (triangulated surface) files
ASCII grid data requires re-interpolation by end-user resulting in minor differences to accompanying GOCAD *.ts surface

Stratigraphic well picks were sourced from PEPS-SA (South Australian Department for Manufacturing, Innovation, Trade, Resources & Energy, 2011) and QPED (Geological Survey of Queensland, 2010) and GABLOG (Habermehl 2001) databases. Previous interpretations of Base Hooray came from DERM (2005). Top of Westbourne contours came from Senior and associates (1997). In the offshore Carpentaria Basin, the western extent of the equivalent of the Hooray sandstone was taken from McConachie and Stainton 1994.
The layer boundary was modified from Habermehl and Lau (1997)/Welsh (2000).
