Relics of the HT/HP events have been identified in the gneiss-amphibolite complex of northern part of the Branisko Mts. The assemblage Grt + Bt + Kfs + Pl ± Sil ± Ky is characteristic of the gneisses and migmatites. The methods of Grt + Bt thermometry and Grt + Bt + Pl + Sil barometry were used for the determination of temperature and pressure. P-T conditions at the boundary of granulite facies were calculated from almandine cores with high pyrope component contents (X^GtMg = 0.19−0.27) and biotite (X^BiMg= 0.4−0.6) in the temperature range 675−770 °C and pressure range 400−630 MPa. A regressive P-T trend was detected in garnet rims. The calculated regression temperatures and pressures are in the range of 590−648 °C and 300−400 MPa, respectively. The regression trend represents probably a compression and depression phase of the same metamorphic event. The pre-Permian age of the event is evidenced by the occurrence of pebbles of the gneiss-migmatite complex in Permian conglomerates. A more precise age determination (Variscan or pre-Variscan stage) is not possible owing to lacking geochronological data. Another retrograde alterations are related to hydrothermal-metasomatic processes and cataclastic deformations both in late-Variscan (blastomylonite and cataclasite pebbles in Permian) and Alpine stage.
