Temperature and pressure of quartz formation on the flat dipping slickenside fault planes covered with quartz and epidote, and quartz from veins in mylonitic zones in the High Tatra granitoid have been compared. The data, obtained by studies of fluid inclusions proved that synkinematic quartz on the slickenside fault surfaces crystallized at higher pressure and lower temperature (1.5 – 1.7 kbar, 212 – 254°C) than vein quartz in mylonitic zones (1.3 – 1.6 kbar, 264 – 316°C). Quartz formation on the flat dipping slickenside faults may be bound to the horizontal compression causing the cold-regime Alpine nappe folding, whereas the post-mylonitic quartz veins formed due to hydrothermal activity probably connected with an older, maybe Variscan stage of the granitoid massif formation.
