Abstract

The Paterson 3D VRML model of the Cottesloe Syncline region in the northwest Paterson Orogen was created using 3D GeoModeller. 3D GeoModeller is an emerging technology that constructs 3D volumetric models based on a range of geological information. The principal benefit of 3D GeoModeller is that it provides geoscientists with a rapid tool for testing multiple working hypotheses. The models were built by members of the Paterson Project, as well as model building specialists within Geoscience Australia as a two-fold exercise. The primary purpose was to test the capabilities of 3D GeoModeller, while the secondary purpose was to evaluate the project's understanding of the 3D geology of the study area. Two 3D models of the Cottesloe Syncline were constructed, the first one utilising geological observations only from the geological map, and the other including the outcrop observations as well as an interpreted solid geology of the area. The resultant Cottesloe Syncline models, including two dimensional maps and images, were exported from 3D GeoModeller and transformed into Virtual Reality Modelling Language (VRML), enabling a wide audience to view the model using readily available software. For more information on how the Paterson Project used 3D GeoModeller to construct the Cottesloe Syncline model, see Constructing geologically-constrained 3D models using 3D GeoModeller. Geographic extent The Paterson Orogen is located in Western Australia and is situated between the Pilbara Craton to the southwest and the Canning Basin to the northeast. The Cottesloe Syncline 3D model covers an area of 30 x 35 km and is situated in the northwest of the Paterson Orogen. Content The Paterson 3D model and associated data sets consist of: a scanned image of the central portion of the Broadhurst 1:100 000 geological map sheet; an image of the Digital Elevation Model; input geological observations from the geological map; additional observations based on an interpreted solid geology; 3D surfaces of the various geological units based on the geological observations; and 3D surfaces based on the geological observations and the interpreted solid geology.

Lineage

Projection: Universal Transverse Mercator (UTM) Zone 51 Datum: Geocentric Datum of Australia (GDA94) Coordinates: Map Grid of Australia 1994 (MGA94) Geology: Scanned image of the Broadhurst 1:100 000 map sheet in the Paterson Range area. Solid & Outcrop Observations: Dem: Pseudocolour image of the Geoscience Australia 9-second Digital Elevation Model (2nd edition). This layer was downloaded from the Geoscience Australia data store as an ArcInfo grid, projected from Geodetic to UTM Zone 51 coordinates, imported into GoCAD as an x, y, z point set and interpolated using an initial 7500 metre triangulation in GoCAD. The data extent matches the polygon coordinate string given above.
