Abstract (in english)
   Riftogenic volcanic rocks occur in all three megaunits, i.e. in the Outer, Central and Inner Western Carpathians (OWC, CWC, IWC). Volcanic rocks were formed during several events from Early Paleozoic to the Tertiary/Quaternary. Based on geochemical and petrological data they can be divided into two groups: (1) within-plate alkali volcanic rocks and (2) transitional tholeiitic volcanic rocks mostly with E-MORB or CT signature. The former were generated during incipient stage of continental crust rifting, the latter during further rift evolution tending to the back-are basin opening. Alkali volcanic rocks associated with early rifting were formed during: (1) Early Paleozoic (IWC), (2) Ladinian-Carnian (IWC), (3) Upper Creataceous (CWC and OWC) and (4) Tertiary/Quaternary. Except for the Creataceous event every rifting seems to be preceded by arc volcanism.
   Transitional tholeiitic volcanic rocks related to the back-arc basin opening were formed in : (1) Devonian (IWC and CWC), (2) Late Carboniferous (IWC) and (3) Triassic (IWC). There are indices of spatial and temporal relations to preserved oceanic crust relics
