Carbon mobilized at shallow depths in subduction zones by carbonatitic liquids

S Poli - Nature Geoscience, 2015 - nature.com
More than half a gigaton of CO2 is subducted into Earth's interior each year. At least 40% of
this CO2 is returned to the atmosphere by arc volcanism,,. Processes that are known to …
