Abstract

The scapolite decarbonation equilibrium Meionite + Quartz = Anorthite + Grossular + CO₂ is used to calculate the activity of CO₂ (a_CO2) in scapolite granulites and lower crustal xenoliths. Calculations of H₂O activities and C-O-H-S fluid speciation for the Furua Granulite Complex in Tanzania suggest that peak metamorphism occurred in the absence of a fluid phase, but they are not consistent with CO₂-flooding as a mechanism for producing lowered water activities in these granulites. -from Authors
