On the basis of a detailed regional mapping of the area between the rivers Axios and Strimon m the Greek part of Macedonia a new understanding of the structure and geological development during the Mesozoic and Tertiary of the innermost zones of the Hellenides has been acquired. The area can be subdivided into five units striking generally NW-SE, which are distinguishable by rock sequence and structure. 1. The Serbo-Macedonian Massif tectonically superimposing the Rila-Rhodope Massif in the East as an independent geotectonic element, is part of an old craton, consolidated during hercynian or pre-hercynian times. It is built up by different gneiss sequences, metabasites, ultramafites and gneissic granites. Within synclines and imbricate structures the transgressive? Upper Paleozoic cover has been preserved. This series of marbles, phyllites and quartzites has been metamorphosed in the higher greenschist facies and interfolded into the basement during a second Mesozoic orogeny. The basement itself suffered an important regional retrograde metamorphism. In the course of this second orogeny syn- and late orogenic granitic and quartzdioritic batholiths intruded the south-western rim of the massif (magmatic phase E of Fig. 1).
