Project is focused at geochemistry and age relations of the Pre-Alpine dike igneous rocks in the Western Carpathians. Origin, time and spatial relations of the dike igneous rocks are going to be solved, based on the geochemical characteristics. Studied rock types will be felsic granitic porphyries, intermediate to basic rocks (kersantitesand spessartites). The main goal of study of these rocks is their age and genetic relations to host rock(crystalline complexes – granites mainly). The last studied rock types are alkaline lamprophyres. Again, their age and genetic relations to their host rock will be defined in the different tectonic units. The modern laboratory methods will be used for interpretations (Rb, Sr, Sm, Nd isotopes) and Ar/Ar to U/Th/Pb dating of apatite, monazite. These data will be obtained by cooperation with foreign institutions (Polish Academy of Science, Krakow, Trinity College Dublin, Kyoto University, Okayama University of Science, University Lund).
