heal.abstract	The mineralogical and geochemical composition of the Kos perlite and its relationship with the other Aegean perlites is examined in this paper. The Kos perlite, which was produced in the latest Aegean volcanic episode, consists of volcanic glass (> 80 %), quartz, feldspar, biotite, magnetite and ilmenite. The volcanic glass is rich in alkalies, while feldspars are of oligoclase-andesine composition. The chemical analysis of Aegean perlites indicates that Kos perlite, which belongs to the eastern part of the volcanic arc, is more alcalic (abundance of Ca and Ba) compared with the other perlites, and that parent magmas of different composition produced the various Aegean perlites.	en
