Permian sandstones, as the cover of the Veporic Nappe of tonalites in the Central Western Carpathians, were anchimetamorphosed during Middle Cretaceous folding events (at T up to 320 °C). This is shown by the presence of metastable phases (half-disintegrated clastogenic biotites and muscovites) as well as by the difference in the composition of clastogenic (muscovite) and authigenic (Ti-phengite, phengitic sericite) micas. The authors discuss the criteria for anchi- and epimetamorphism, as well as the possibilities of Alpine diaphtoresis of the crystalline basement.
