Summary:The origin of the Eastern Varnountas plutonite is studied. The geochemistry showed that the plutonic sequence is the result of fractional crystallization of an initial magma with composition similar to a hornblende-biotite monzodiorite (EAIA). The geochemical and isotopic data of the initial magma are presented, and it is attempted to determine its parental source. Several major and trace element petrogenetic models are examined for the origin of the plutonite in a volcanic arc geotectonic environment. Finally, it is concluded that the initial magma of the plutonite is derived by partial melting of a LILE-enriched upper mantle.
