During 2013-2014, Geoscience Australia, in collaboration with the Geological Survey of South Australia (PACE Frontiers), the Geological Survey of Western Australia (Royalties for Regions Exploration Incentive Scheme), and AuScope, funded acquisition and processing of the Eucla-Gawler 2D Vibroseis deep crustal profiling seismic survey 13GA-EG1. The subject model interpolates between this seismic line and another shot in 2008, the 08GA-OM1 seismic line. It images the western Gawler Craton from where it abuts the central Gawler Craton in the east to where the Coompana Province covers the lower Gawler crust in the west. The foundations of the model are fault 3D surfaces derived from seismic and magnetic interpretations. Gravity and magnetic inversions were run to investigate the relationship between the different fault-bounded blocks.

    Notes: 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.  The metadata for the subject 3D model, stored elsewhere as CatApp 3172, has been made downloadable from here as a pdf document. It lists the GIS source files for multiple discrete 3D surfaces which have been incorporated into the model.
