This session welcomes abstracts on any topic in solid Earth science that doesn't fit neatly into a more specific session. We invite contributions from seismology, tectonics, geodynamics, geodesy, volcanology, geochemistry, and geophysical instrumentation, whether they present new observations, modelling, methods, or field results. Work that crosses disciplinary boundaries or is still taking shape is especially welcome, as are submissions from students and early-career researchers looking for a venue to share their research with the broader solid Earth community.
