Abstract

Cordierite from the granulite facies crustal segment of southern India shows entrapped CO₂ within matrix channels and fluid inclusions. A combination of, visual decrepitation and stepped thermal analysis for CO₂ extraction distinguishes the inclusion and channel fluids, and allows the prediction of CO₂ zonation in cordierites crystallizing in deep crustal environments.
