Defining the distribution and thickness of sedimentary basins

Curnamona Sedimentary Basin 3D Model location mapThe Palaeo-Mesoproterozoic Curnamona Province is overlain by sedimentary basins containing Neoproterozoic, Cambrian, Mesozoic and Cenozoic sediments. These cover sediments can introduce considerable complexities and costs to mineral exploration within bedrock.

This 3D model of cover overlying the Curnamona Province was created as a convenient way of visualising the distribution and thickness of these basin sediments.

The model enables depth estimations from the surface to key surfaces, including top of Palaeo-Mesoproterozoic, base of Cambrian, base of Mesozoic and base of Cenozoic. Depth estimations are derived from a combination of drillhole data, seismic interpretation and aeromagnetic modelling.
