Aragonite-bearing blueschists on Arki Island, Dodecanese, Greece
European Journal of Mineralogy (June 1992) 4 (3): 527-537


Aragonite-bearing blueschists occur in the Temenia nappe forming the lowermost unit of the Dodecanese nappe pile on the island of Arki, S of Samos and ENE of Patmos. The critical mineral assemblages glaucophane-phengite-chlorite-albite-epidote-aragonite in the blueschists and albite-epidote-chlorite-phengite-winchite- calcite (probably after aragonite) in the related isofacial greenschist indicate a subduction-related metamorphism at 7-10 kbar, 300-400 degrees C. EPMA results are given for epidotes, amphiboles (glaucophane and winchite), chlorites, phengites and carbonates. The geological significance of this new blueschist occurrence is discussed, and it is suggested that there is a similar development of the Temonic nappe on Leros.
