Along-arc, inter-arc and arc-to-arc variations in volcanic gas CO2/ST ratios reveal dual source of carbon in arc volcanism
Some 300–600 Tg of volatiles are globally vented each year by arc volcanism. Such arc gas
emissions have contributed to past and present-day evolution of the Earth atmosphere and …
