At lower elevations, near the river, are relict lenses of a peculiar talc-kyanite-dravite “white schist” (Kulke & Schreyer, 1973; Kulke, 1976; Faryad, 2003); this rock, intercalated in the lowermost part of the marble unit, is thought to represent a high-pressure metamorphic facies of late Precambrian age (Kulke and Schreyer, 1973; Faryad, 1999).
