Amphibolites from the Serbo-Macedonian Massif (Northern Greece)

Abstract

Amphibolites from the Vertiskos and Kerdyllia series of the Serbo-Macedoninn massif, Northern Greece, are examined in terms of their mineralogy and petrochemistry. Evidence based on data derived from the geochemistry and mineral parageneses, indicate that the rocks in study arc of basic igneous origin and have metamorphosed in the amphiboli tefacies. The nature of the parental magma, as deduced from the normative compositions and chemical variation trends is in general of tholeiitic compositi on. Discrimination diagrams based on major and trace elements suggest a possible ocean-floor tectonic affinity.
