Sažetak
The magmatic body of Vratnik consists mainly of composite magmatic rocks (andesite and basalt protoclasts inserted into dacite) and pyroclastic rocks.The rocks have been affected by strong low- temperature hydrothermal alteration. Calc- alakline affinities are inferred on the basis of Ta/Yb and Th/Yb ratios. The REE- and trace- element patterns are common features of subduction related magmas. The high Pb/Nd, low Nb/U and low Sr/Nd ratios may indicate high cntribution of continental material to parental magmas.
