3D Geological Model of Rosebery Mt Lyell

The Rosebery-Lyell 3D geological and geophysical model is an extension and refinement of previous MRT 3D models in the region. It expresses a new structural synthesis based on mapping and multiple cross sections produced by numerous geologists over several decades. It extends to a depth of 10 km within the area depicted at left. The model is constrained by 3D geophysical modelling using MRT's gravity and magnetic survey data coupled with drilling and rock physical property databases. This information has been used to derive uncertainty estimates for each element in the model volume. The model files also include nominal density and magnetic susceptibility estimates obtained for each voxel, thus incorporating intra-unit variations.
