The pebbles of granitic and rhyolitic rocks from conglomerates of the Pieniny Klippen Belt Cretaceous flysch can be divided on the basis of zircon study (typology, zoning of crystals, chemical composition) into three main groups: 1 − granites, granite porphyries and rhyolites of the exotic Upohlav type with the tendency to A-type granite suite probably analogical to some post-orogenic (Permian to Triassic) intrusions of Alpine-Mediterranean Belt; 2 − granites, granodiorites to leucotonalites and rarely pegmatites of the Kriva type similar to some orogenic Hercynian granitic rocks from the Central Western Carpathians (Tatric and Veporic Units), and 3 − porphyric granite of the Lubina type which can be compared with orogenic (Hercynian ?) calc-alkalic intrusion.
