3D Architecture model of the western Gawler Craton
The acquisition and interpretation of the deep crustal seismic line 13GA-EG1 has allowed a new 3D model to be constructed for the western Gawler Craton. The new 3D model expands on the Eastern Gawler IOGC / Woomera Prohibited Area model, which sits to the north and east of this seismic line.
Interpretations used to construct this model were derived from a cross-border collaborative work program between the Geological Survey of South Australia, the Geological Survey of Western Australia and Geoscience Australia, initiated by the collection of seismic line 13GA-EG1.
This is the first of three models which will cover the length of the seismic line 13GA-EG1; the others being the Albany-Fraser Orogen model in Western Australia and the Coompana model which straddles the WA/SA border. These are being worked on and will be published in the coming years to produce a continuous crustal architecture and density model between the Gawler and Yilgarn Cratons.

- Statement
- This model is presented as a preliminary example of work in progress, and its accuracy (spatial or otherwise) should not be relied upon for guiding exploration or other decision-making processes. It is influenced by the following necessary constraints: - Positional accuracy - horizontal accuracy of formation boundaries is variable (interpreted); vertical accuracy of the interpolated formation surfaces, topographic and basement surfaces are variable due to resampling (topographic surface), interpretation (formation boundaries) and interpolation; - Attribute accuracy - geological attributes are based on interpretation of features in the subsurface which are not directly observable; thus they are subject to alternative interpretations.
