Small intrusions of post-orogenic Permian granites — POG (290–250 Ma; U-Pb and Rb-Sr ages) occur in the Western Carpathians (Slovakia) and Pannonian area (Hungary). Group (1) hypersolvus to subsolvus Turcok, Upohlav, Velence and Hroncok biotite (leuco)granites, microgranites and granite porphyries show A-type characteristics high Si, K, REE, Ga/Al, sometimes Na, Rb, Zr, Nb; low Ti, Mg, Ca, P, Ba, Sr and V contents. Group (2) Spis-Gemer two-mica leucogranites and porphyries show the specialized S-type characteristics: high Si, K, Rb, Sn, B, F; and low Zr and REE. Data indicate highly temperature (solidus T~750 °C), dry (1–3% H₂O), and variable oxygen fugacity of magma for group (1); and low temperature (T_s~600–650 °C), low fO₂ and water+fluorine-rich magma for group (2). Emplacement pressure conditions for both groups were estimated at 2 kb for granites s.s. to 0.5–1.5 kb for porphyry and microgranite dikes. POG originated after Variscan orogeny in transtensional-extensional regime, probably from middle-lower crustal (meta)igneous protolith for group (1), and middle-upper crustal metasedimentary or mixed protolith for group (2).
