Title: Exploring for minerals, not anomalies: Developing quantitative interpretations of MT models.

Abstract: Exploration geophysicists are well acquainted with making quantitative interpretations of near-surface geophysical data. There is a good understanding of how shallow anomalies in potential field, resistivity or EM datasets relate to mineralisation. However, as exploration models begin to include the lower crust and the lithospheric mantle, there remain significant gaps in our interpretation of deeper geophysical data. In this talk, I will highlight some new advances in our ability to produce quantitative interpretations of these deeper geophysical data, with a particular focus on MT and its joint interpretation with seismics. I will show the newly released software 'MATE', which allows MT models to be interpreted in terms of temperature and composition, and discuss new results from the Eastern Goldfields Superterrane of the Yilgarn Craton, which show how quantitatively interpreted MT models can feed into improved exploration strategies.

Bio: Dr Kate Selway is a geophysicist and researcher who specialises in the MT method and improving interpretations of mantle geophysics. She recently completed an ARC Future Fellowship based at Macquarie University and has previously held research positions at the University of Oslo, Lamont-Doherty Earth Observatory, Yale University and the University of Adelaide, after completing her PhD at the University of Adelaide in 2007. Her research has spanned giant mineral deposits in Australia, active rifting in East Africa, and mantle uplift in Greenland and Antarctica.
