- •
Ubiquitous CO2-rich FI in quartz from granulites contain small amounts of H2O.
- •
H2O in CO2-rich FI is only revealed when analyzed by Raman at ~ 150 °C.
- •
In garnet-hosted FI the H2O component is present as hydrogarnet.
- •
Pressures inferred from CO2 FI in granulites have been underestimated.
