Hydrogen isotope behavior during rhyolite glass hydration under hydrothermal conditions
Michael R. Hudak, Ilya N. Bindeman, James M. Watkins, Jacob B. Lowenstern
2022, Geochimica et Cosmochimica Acta (337) 33-48
The diffusion of molecular water (H2Om) from the environment into volcanic glass can hydrate the glass up to several wt% at low temperature over long timescales. During this process, the water imprints its hydrogen isotope composition (δDH2O) to the glass (δDgl) offset by a glass-H2O fractionation factor (ΔDgl-H2O = δDgl – δDH2O) which is approximately −33‰ at Earth...
