Geoscience Data
Interpretive reports, an Explorers Guide to the Stavely geological province and a 3D model of the area by the Geological Survey of Victoria is nearly completed. Public release of this information is expected by the end of December 2017.

Stavely 3D model nearing completion and publication
In mid October the Geological Survey of Victoria presented the complete Stavely 3D model and workflow at the Australian Institute of Geoscientists (Victoria Branch) annual technical day. The model and accompanying report will be published soon.
The Stavely 3D model is an explicit full-crustal thickness geological unit and fault-framework model. It was designed to represent, in a way that is consistent with available data and in three dimensions, the interpretation of the geometries and inter-relationships of major regional to district-scale structural and stratigraphic geological elements known to occur within the central portion of the Grampians-Stavely Zone.
Potential uses of this model include, but are not limited to:
-
Construction of crustal-scale cross-sections in any orientation or position within the zone.
-
Construction of depth-slices at any position within the Zone.
-
Exploring the possibility of correlation between different or widely separated mineral deposit locations.
-
Identification of common plumbing systems for different or separated mineral systems.
-
Examining the likely regional structural controls on smaller-scale structural systems (structural systems are typically scale-invariant).
-
Drill program design and orientation.
-
Geophysical acquisition design.
-
Depth to economic basement assessments.
The 3D model framework forms the basic framework for fluid-flow modelling. It is also a starting point for 4D reconstructions of the crust (progressive removal of the effects of structural systems from youngest to oldest, as already attempted in 3D).
The images below are highlights from the Stavely 3D Model. The image on the left is the complex regional attributed fault network. The image on the right is the Cambrian volcanic belt segments. The 20,000 square kilometre Stavely Project area (yellow outline) is shown for reference.
