Joint Inversion of 3D Seismic and MT Data
“Joint inversion is an exciting new area of geophysical research, in which different types of 3D geophysical data are combined to produce better-resolved and more accurate geological models of mineral deposits than a single dataset can provide.” Graham Heinson, University of Adelaide

To investigate the advantages of co-located seismic and EM surveys in terms of mutual constraints and cooperative inversion that significantly improve geological interpretation over that which can be achieved from a single technique.
Background & Aims
High quality geophysical data sets are collected around existing mines and mineral exploration targets. Such geophysical measurements are used to image the earth, often in three dimensions (3D), through a process called inversion. However, given the depth of many target regions, these images generally have poor resolution and suffer from an ambiguity of interpretation. Cooperative inversion is a hot area of geophysical research, combining more than one data set to produce a single geological model. Not only do we get more accurate models of the earth by using multiple data sets, we also benefit from the mutual
constraints between data sets.
This project will combine existing 3D seismic and MT data sets to produce workflows capable of generating more accurate and better resolved models for deep mineral exploration and mineral resource targeting.
