Mesozoic alkali lamprophyres from the Malé Karpaty Mts and Nizke Tatry Mts granitoids have a similar petrographic pattern. The textures are phyric, with amphibole and clinopyroxene (Cpx) (and/or olivine) phenocrysts. Cpx are zonal and correspond to diopside. Amphibole are zoning too and correspond to kaersutites. On the basis of chemical composition they can be ranked with alkaline lamprophyres. The K/Ar age (approx. 100 Ma) of these dykes corresponds to the age of the Cretaceous alkaline basalt/basanite in the Križna Nappe of the Central Western Carpathians.
