At these lowest grades of metamorphism, the pelites are characterized by clays and the carbonate rocks by calcite and/or dolomite + quartz. Greenschist Facies assemblages are distributed in the western Blue Ridge Belt.Contact Supplier
Earlier stages in the metamorphism of siliceous dolomites.
In the outer band of dolomite now described, talc and tremolite are the dominant new mineral phases, and their mutual relations make clear that talc is the initial product in the metamorphism.Contact Supplier
