Oxygen and hydrogen isotope fractionation factors in the talc-water and serpentine-water systems
have been determined by laboratory experiment from 250 to 450°C at 50 MPa using the partial
exchange technique. Talc was synthesized from brucite + quartz, resulting in nearly 100%
exchange during reaction at 350 and 450°C. For serpentine, D-H exchange was much more rapid
than 18O-16O exchange when natural chrysotile fibers were employed in the initial charge. In
experiments with lizardite as the starting charge, recrystallization to chrysotile enhanced the rate
of 18O-16O exchange with the coexisting aqueous phase.
