Presenter

Dr Kate Selway

Senior Research Fellow with the MinEx CRC at UniSA

After being inspired to pursue a research career after an Honours year working with MIMDAS, Dr Kate Selway received her PhD from the University of Adelaide in 2007, followed by postdoctoral research positions at Yale, Columbia University (Lamont-Doherty Earth Institute) and the University of Oslo. Kate was brought back to Australia in 2017 when she was awarded an Australian Research Council Future Fellowship, which she held at Macquarie University until early 2021.

Since then, Kate has been happily back in Adelaide as a Senior Research Fellow with the MinEx CRC at UniSA. Kate's research is focussed on producing quantitative interpretations of magnetotelluric models in terms of the composition and temperature of the Earth.

Over her career she has applied this to mineralised regions such as the Stuart Shelf and the Eastern Goldfields Superterrane, to tectonic settings including craton development and the East Africa Rift, and to glacial isostatic adjustment calculations at the poles.


Talk Title: Magnetotellurics What it can (and can’t!) do to help mineral exploration

Talk outline:

There has been tremendous uptake of magnetotellurics (MT) for mineral exploration across Australia in the last decade. As a relatively new technique, MT has sometimes been seen as an answer to all our exploration questions, and has sometimes been seen as an answer none of them!

Of course, the reality is somewhere in between. In this talk I will outline the main ways MT can help exploration, from constraining depth to basement to identifying conductive anomalies within the crust and lithospheric mantle. I will describe some new developments that enable us to interpret those anomalies in the context of mineral systems and will discuss the remaining uncertainties in our interpretations, highlighting the exploration questions that MT can help to answer and those that we need additional tools to answer.
