The Serres-Drama granitic complex is situated in the Rhodope massif (North Greece). It comprises a broad spectrum of rock-types (gabbro, dioritic xenoliths, mon- zonite, quartz monzonite, granodiorite, granite, aplite and pegmatite veins).
From petrographical, mineralogical, geochemical and field studies, it can be seen that the granitic complex separates distinctly into two groups of rock-types, termed the "intermediate" group (granite, granodiorite and quartz monzonite) and the "basic" group (gabbro, dioritic xenoliths and monzonite). Aplites and pegmatites have not been classified in this group.
The Serres-Drama granitic complex is a calc- alkaline "I-type" complex, sensu Chappell and White (1974). It is similar to the "magnetite" series complexes described by Ishihara (1977, from Takahashi et al, 1980). Chemical characteristics indicate that it originated in the compressional zone (Petro et al,
1979) of a mature continental arc system (G.C. Brown, 1982).
