Description

Abstract:

3D model of the Tanami region including numerous geological and geophysical datasets - Web veiwable X3D model.

A new 3D model of the Tanami region has been constructed based on the results of the 2005 Tanami Seismic Collaborative Research Project. The interpreted seismic data consist of four regional traverses that were tested by gravity modelling. The model incorporates the whole of the crust from the surface down to the mantle. Results include an interpreted suture between the Tanami and northern Arunta regions that was active prior to the deposition of the Tanami Group. The model was produced using 3D GeoModeller, a new mathematically based modelling package that constructs 3D volumetric models based on geological information.
