Notes on petrogenesis of alkali rocks of Pancardi

© Z.M. Lyashkevich

In the period following Triassic up to nowadays three main phases of magmatism were distinguished within the limits of Pancardi (Pannonian depression, Carpathians and Dinarides): Mesozoic, Miocene and Pliocene-Pleistocene. During the Mesozoic phase the intrusion of mainly ultramafic and mafic magmas occurred, during the Miocene - intermediate and acid magmas, during the Pliocene-Pleistocene - potassic to ultrapotassic. By the composition and age the alkali rocks of Pancardi correspond to the Cenozoic volcanism of Western Europe and belong to the type of intraplate magmatism of the continents. They are of mantle-plume genesis and describe the state of the depth dynamics of the Earth of the modern period.
