Quaternary volcanism (magmatic, including pyroclastic and volcaniclastic and cryovolcanism) is prevalent on Earth in many geodynamic contexts, revealing mantle compositional changes and dynamics. Although they occur with long eruption intervals, there remains a lack of evidence linking crustal architecture to plutonism and volcanism. Quaternary magmatism significantly impacts sediment production and discharge, influences climatic, and has critical implications for human society and infrastructure. This session highlights several advanced approaches in emerging fields including, but not restricted to, petrology and geochemistry, radiometric age dating, bio-weathering products and sediment characteristics in continental and marine setting as they provide a link to past plutonic activity, volcanism, tectonics-climate evolution and bio-productivity.
