Abstract
Geochemical studies on melt inclusions proposed that H2O-rich crustal magmas often suffer CO2 fluxing. In order to explore kinetics of H2O-CO2 interaction upon CO2 fluxing, we conducted volatile exchange experiments in an H2O-CO2-rhyolite system. We observed that bubbles pre-existing in an H2O-rich magma may dissolve to shrink as a result of volatile exchange with a CO2-rich fluxing fluid.
