A new type of rare-element Be-Nb-Ta mineralization can be defined in the Western Carpathian crystalline complexes; it is bound to granitic pegmatites genetically connected with Hercynian granite intrusions. The mineralization has been characterized on the site Moravany nad Vahom (rare-element, accessory, rock-forming minerals, rocks), however, the described mineralization type is assumed to occur also in other Western Carpathian regions, which allows a new view on the character of pegmatites and rare-element mineralization in this region.
