dc.description.abstractIn the southwestern Goias State, the rocks of the Goias Magmatic Arc present mineral assemblages typical of the amphibolite facies. Thermobarometric calculations show that P and T conditions for associations involving amphibole + biotite + kyanite + staurolite + garnet + plagioclase + muscovite, biotite + garnet + plagioclase + muscovite, amphibole + biotite + garnet + plagioclase, belong to the middle amphibolite facies in the staurolite-kyanite field, reaching temperatures and pressure higher than 600 degrees C and 7 kbar, respectively. The P-T path is clockwise and the values obtained by thermobarometric calculations are interpreted as a retrometamorphic reequilibrium in the amphibolite facies.
