Abstract On the island of Arki, aragonite-bearing blueschists are recorded within the Temenia Nappe forming the lowermost unit of the Dodecanese nappe pile. The critical mineral assemblages glaucophane - phengite - chlorite - albite - epidote - aragonite (- calcite) in the blueschists and albite - epidote - chlorite - phengite - winchite - calcite (probably after initial aragonite) in the related, isofacial greenschists indicate a subduction-related metamorphism with pressures of 7 to 10 kbar and temperatures of 300 to 400°C. The geological significance of this new blueschist occurrence is discussed
