Zircon geochronology of the “Kékkút quartz porphyry”, Balaton Highland, Transdanubian Central Range, Hungary
U/Pb data on single zircons from acidic volcanics are presented from the Kekkut-4 borehole, Balaton Highland, Transdanubian Central Range, Pelso Mega-Unit. Generally accepted as Lower Permian in age, they were also considered - due to some metamorphic features - to belong to the metamorphic, Lower Paleozoic basement. Clear, elongated crystals of these thick, acidic volcanics are regarded as co-genetic magmatic products, supplying a U/Pb age of 291.4±4.7 Ma (Lower Permian), representing the first radiometric magmatic age-dating of Upper Paleozoic acidic volcanism in this tectonic unit.
