Asenitsa unit metapelites (Central Rhodope massif) have a high variability in mineral, bulk chemical and trace element composition. Kyanite, staurolite and garnet are the major minerals in schists and show intensive retrograde change. Discrimination diagrams based on immobile trace elements indicate continental island arc or active margin setting of deposition.
