Experimental and petrological constraints on local-scale interaction of biotite-amphibole gneiss with H2O-CO2-(K, Na)Cl fluids at middle-crustal conditions: Example from the Limpopo Complex, South Africa

Experimental and petrological constraints on local-scale interaction of biotite-amphibole gneiss with H2O-CO2-(K, Na)Cl fluids at middle-crustal conditions: Example from the Limpopo Complex, South Africa

Reaction textures and fluid inclusions in the ∼2.0 Ga pyroxene-bearing dehydration zones within the Sand River biotite-hornblende orthogneisses (Central Zone of the Limpopo Complex) suggest that the formation of these zones is a result of close interplay between dehydration process along ductile she...
