WitrynaPhyllite: Fine-grained and very finely schistose rock, the platy min erals of which consist mainly of sericite. Sericite imparts an overall silky sheen to the schistosity planes. The grain size is coarser than in slates, but finer than in mica schists. The amount of phyllosilicates (sericite + some chlorite ± biotite) exceeds 50 %. WitrynaMetamorphic Grade • Example: prograde metamorphism of a pelitic rock. – Low grade — shale protolith. • Clays recrystallize into larger, aligned clays to yield a slate. • Clays neocrystallize into tiny, aligned micas in a phyllite. – Intermediate grade • Micas recrystallize and grow large to form a schist. •
