Revised Great Artesian Basin Jurassic-Cretaceous sequence boundary

The revised Great Artesian Basin Jurassic-Cretaceous boundary was produced by the Great Artesian Basin Water Resource Assessment (GABWRA) . This boundary is modified from that of Habermehl and Lau 1997 and incorporates the revised boundary from the South Australia Great Artesian Basin (Eromanga Basin) Hydrogeological map 2012. Modifications made to sections of this boundary as part of the GABWRA include major revisions to the Surat and Clarence-Moreton Basins boundary; southern part of the Coonamble Embayment; NW Queensland boundary within the Lawn Hill and Westmoreland 1:250K map sheet areas.


The dataset includes boundaries of basement inliers within the GAB


Note: Habermehl and Lau 1997 boundary included Triassic GAB formations in Queensland which were not considered by the GABWRA.


Data is available in polygon format.

METHODS:

Habermehl and Lau (1997) was modified based on interpretation by Jim Kellett (Geoscience Australia) using references listed above.


Lines representing the Great Artesian Basin boundary and basement inliers were produced in conjunction with the GABWRA Great Artesian Basin watertable elevation dataset.


The Polygon layer was generated from the linework.


Basement inlier areas (defined in the GABWRA location of basement inliers data set) were deleted to form holes within the polygon.
