Tertiary magmatism within the Republic of Macedonia; a review


Acta Vulcanologica 13(1-2): 57-71
Tertiary magmatism within the Republic of Macedonia; a review
Widespread Tertiary magmatism of both orogenic and within-plate signatures developed within the Macedonian part of the Dinarides. Orogenic magmatites (predominantly volcanic rocks) are present in 5 areas (from east to west): Osogovo-Besna Kobila, Kratovo-Zletovo, Bucim-Borov Dol, Dojran and Kozuf. The age of the igneous rocks decreases in the same direction: from Priabonian-Early Oligocene at Osogovo-Besna Kobila area, Early Oligocene-Miocene in Kratovo-Zletovo and Bucim-Borov Dol to Late Miocene-Late Pliocene in Kozuf. The Osogovo-Besna Kobila area contains only acid volcanics (trachydacites to dacites), occurring mainly as subvolcanic to hypabyssal bodies. They have collision-related chemical characteristics. Latites and andesites to dacites predominate in the Kratovo-Zletovo area, but a monzonite pluton is also be found. Only the shoshonite series (from latites to trachyrhyolites) is present in Bucim-Borov Dol, and trachytes in Dojran area. The Kozuf area, which consists of two series; (1) shoshonitic (high-Mg shoshonites, latites and trachydacites) and (2) andesitic series (low-K andesites and high-Fe rhyolites), seems to be the most complex volcanic field. Magmatites in the last three areas have island arc signatures. The within-plate volcanics rocks are high-K to ultra-K mafic igneous rocks (phonotephrites) accompanied by some absarokite, shoshonite to latite occurrences. Their age is Upper Miocene-Pliocene. These rocks are grouped in 4 areas: Kumanovo, Skopje-St. Nikole, Stip and Demir Kapija. The high Mg# and the high Cr-Ni contents of the phonotephrites, together with Fo-rich olivine phenocrysts suggest their asthenospheric origin.
