Abstract: 

In this presentation we present some of the activities from the MinEx CRC/Loop Consortium/DARE ITTC work on building 3D geological models using geophysical data. The talk will briefly highlight the following areas:

Integration of automatic implicit geological modelling in deterministic geophysical inversion (https://doi.org/10.5194/se-15-63-2024)

Some results from the Tomofast-x inversion platform, with its ability to use detailed petrophysical statistics as constraints on gravity/mag inversion (https://doi.org/10.5194/egusphere-2023-2243, https://doi.org/10.1190/geo2019-0633.1)

The use of a massive library of synthetic 3D geological models and their gravity and magnetic response as a Machine Learning training set (https://doi.org/10.1016/j.cageo.2021.104701, https://doi.org/10.5194/essd-14-381-2022) and

Our latest work on navigating regional geophysical data using a combined feature extraction/non-linear dimensionality reduction technique method.

Bio:

Mark Jessell is a Professor at the Centre for Exploration Targeting at The University of Western Australia. His scientific interests revolve around the tectonics and metallogenesis of the West African and Guyanese Cratons (WAXI & SAXI) microstructure studies (the Elle platform), and integration of geology and geophysics in 3D (the Loop project). He returned to Australia from France on a Western Australian Fellowship focused on improving the links between geological and geophysical data analysis in 3D via analysis of the geological and topological uncertainty. In 2013 he was awarded the Geological Society of Australia Hobbs Medal for major contributions in structural geology. He is a director of the not-for-profit Agate Project Ltd which supports higher education in the Earth Sciences in Africa.
