The amphibolite-facies assemblage plagioclase + hornblende grows at ∼ 550 °C from chlorite + epidote. In course of this reaction garnet may be formed. White micas, particularly paragonite, as well as kyanite coexisting with hornblende, are indicative of pressure-dominated amphibolite-facies conditions (epidote–amphibolite-facies).
