Abstract
Late Cretaceous metamorphites, investigated in a profile near Lendas/Asterousia Mountains (southern coast of Crete), consist of the following lithological units (from the base to the top): massive ortho-amphibolites, which may contain diopside besides plagioclase and magnesiohornblende; cordierite-garnet-sillimanite-biotite gneisses; calc-silicate rocks and marbles with salitic pyroxene, pargasite, magnesio-homblende, cummingtonite, grossular-andradite garnet, wollastonite, and scapolite. Meta-ultramafics with anthophyllite, tremolite, olivine, and orthopyroxene are intercalated with the calc-silicate series. The mineral parageneses in the four classic bulk rock compositions - basic, pelitic, siliceous-calcareous, and ultrabasic - afford an opportunity to characterize the metamorphic facies in detail. From these parageneses, and from the Mg/Fe2+ ratios of coexisting cordierite and garnet, temperatures between 650 and 700°C and pressures between 4 and 6 kbar have been estimated for the conditions of metamorphism.
