Alberton-Mathinna 3D Geological and Geophysical Modelling Alberton-Mathinna 3D Geological and Geophysical Modelling

The Alberton-Mathinna 3D geological and geophysical model extends to a depth of 5 km within the area depicted. It expresses a new synthesis based on geological mapping together with geophysical and structural interpretations previously produced by MRT and other geoscientists over several decades. 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.

The geological model was constructed using the GOCAD® Mining Suite from Mira Geoscience, with initial geophysical inversions via the VPmg code. Further geophysical modelling and uncertainty characterisation was carried out with the GeoModellerTM software from Intrepid Geophysics.

The 3D model files are available for download below in several forms:
