Blueschist and Eclogite Facies Fig. 25-2. 2. Temperature- pressure diagram showing the generally accepted limits of the various facies used in this text. Winter (2001) An Introduction to Igneous and Metamorphic Petrology. Prentice Hall.
Blueschist and Eclogite Facies The blueschist facies is characterized in metabasites by the presence of a sodic blue amphibole stable only at high pressures (usually glaucophane, but crossite or riebeckite is possible) The association of glaucophane + lawsonite is diagnostic. Albite breaks down at high pressure by reaction to jadeitic pyroxene + quartz: NaAlSi 3 O 8 = NaAlSi 2 O 6 + SiO 2 (reaction 25-3) Ab Jd Qtz
