3D Geological Modelling

The 3D geological model of Victoria represents the culmination of a major period of geological data acquisition and interpretation in Victoria. It is based on world class surface geological mapping supported by comprehensive, regional scale airborne magnetic and radiometric surveys, ground gravity surveys, regional seismic surveys in central and western Victoria and extensive seismic survey coverage in the younger basins.

The 3D model is a view of the full thickness of the earth's crust across the entire State. It can be used to analyse resource potential, predict the location of undiscovered earth resources and allow the development of four-dimensional resource management frameworks for the State's energy and groundwater resources. Seamless Geology, one of the Geological Survey of Victoria's major initiatives, contributed to the 3D model.

The following objects are accessible via the “Model Tree”:

Group

  • Intrusions – grouped by structural zones. Only the large intrusions are included within this model
  • Faults – Major faults from all zones
  • Stratigraphy – stratigraphic horizons from all zones
  • Sedimentary Basins – surface representing the base of the Murray, Otway and Gippsland basin
  • Primary commodities - Location of known mineral occurrences and deposits presented in the 1:1,000,000 Minerals of Victoria map compiled in 1993 by the Geological Survey of Victoria, as available on GeoVic

Curve – Victorian border and structural zone outlines

Surface – Topographic and moho surface

Key 3D Regional Models

In addition to the statewide model, individual 3D geological models are available for the following key regions:

  • Bendigo Zone
  • Glenelg/Grampians-Stavely Zone
  • Redesdale and part Pyalong
  • Gippsland Basin
  • Otway and Torquay Basin
  • Murray Basin
  • Stawell Zone
  • Walhalla-Woods Point-Tallangallook special map area
  • Latrobe Valley coal resource extension
