Low Density Carbonic Fluids in the Archean Granulite Facies Terrain of the Jequié Complex, Bahia, Brazil

The 2.7 Ga old high-grade metamorphic rocks of the Jequi Complex of Bahia include charnockites, enderbites, and late pink potassic granites. Mineralogic P-T determinations for the granite terrain yield 4-5 kb/750-850C for the peak of metamorphism. Microthermometry of fluid inclusions in quartz was p...
