Description
23rd annual meeting of the Asia Oceania Geosciences Society - AOGS 2026. Fukuoka, Japan.SESSION: Investigating Earth's Structure and Evolution with Large-Scale Magnetotelluric Arrays: Progress, Perspectives, and Insights
Session Organizers and Conveners: Zhang Kun , Matthew J. Comeau, Makoto Uyeshima.
The mechanisms governing Earth’s internal structure and evolution remain incompletely understood and represent a central challenge in geoscience. Characterizing the planet’s internal electrical resistivity structure provides a powerful approach to address these questions, as electrical resistivity is highly sensitive to the presence and migration of melts, fluids, and volatiles — key drivers of deep tectonic processes. Magnetotelluric (MT) exploration, which enables imaging of subsurface electrical resistivity, has therefore
emerged as a vital tool for probing the lithosphere and asthenosphere. Over the past decades, this has led to the establishment of large-scale MT arrays across the globe, including major country-wide arrays in, for example, Australia, China, Japan, Mongolia, and the United States.
In this session, we invite researchers to share their findings from MT investigations—ranging from methodological advances to regional case studies—that shed light on the structure and dynamics of Earth’s interior. We especially encourage contributions that integrate complementary geophysical, geochemical, and geological observations, stimulating cross-disciplinary dialogue, and highlight the future potential of large-scale MT arrays in understanding deep tectonic processes.
