Curnamona Province was created as a convenient way of visualising the spatial distribution and thickness of these basinal sediments. The model enables users to make estimations of vertical distances from the surface to key surfaces, including depth to top of Palaeo-Mesoproterozoic, base of Cambrian, base of Mesozoic and base of Cenozoic. The inferred forms of these key surfaces are derived from a combination of drillhole data, seismic data interpretation and aeromagnetic data modelling.

      This model is presented as a 'proof of concept' only for the GOCAD software which the Geological Survey has recently begun to use, and its accuracy (spatial or otherwise) should not be relied upon for guiding exploration or other decision-making processes. The horizontal accuracy of the geographic locations of drillholes is variable due to the method of spatial data capture (map, hand-held GPS, differential GPS, etc); likewise, the horizontal accuracy of the sedimentary basin boundaries is variable (due to the ways they were interpreted); and the vertical accuracy of the modelled formation surfaces, topographic and basement surfaces is variable due to resampling (topographic surface), interpretation (formation boundaries), and necessary gridding interpolation.
