Accepted expressions of interest will be due for submission to Exploration Geophysics by 31 March, 2022.Scope of issueAlthough the magnetotelluric (MT) technique was first used in Australia in the 1960s, it has only been widely adopted by academia, government, and industry over the last two decades, bolstered by the realisation of its important role in mineral and energy exploration undercover.To date, there are many MT surveys and associated innovations across Australia. The national MT programme - Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP), which is half way to covering the continent, has revealed major insights into the tectonic evolution and mineral systems of Australia, and inspired subsequent infill-surveys for further investigations.This special issue invites papers that focus on MT studies in Australia, including but not limited to applications in resource exploration, modelling/inversion, interpretation, innovations, and representative case studies.Special editorsKate Robertson Kate.Robertson2@sa.gov.auGraham Heinson Graham.Heinson@adelaide.edu.auJingming Duan Jingming.Duan@ga.gov.au13 PREVIEW OCTOBER 2021'
