Abstract: Garnets originating from Miocene dy-normative, medium-K andesites as well as from a Mesozoic fine-grained albite granite have been petro-graphically investigated. It has been argued that the former ones with an average composition of 57 to 65% almandine, 14 to 22% pyrope, 10 to 24% grossular and 2 to 5% spessartine are high-pressure liquidus phases, while the second ones (almandine 71 to 74%, pyrope 12 to 18%, grossular 3.5 to 5.5% and spessartine 5.6 to 11%) have apparently crystallysed in a low-pressure environment due to a late magmatic, metasomatic event.Journal: Fragmenta Minerologica et PalaeontologicaJournal abbreviation: ISSN: 0367-2697Publisher: Népművelési Propaganda Iroda, BudapestEditor(s): Vörös, A. & Nemes, I.
