Abstract
Highly potassic fine-grained ultramylonites with large mylonitized and biotitized garnets from Plešovice quarry in the Blanský les granulites, contain large well crystallized zircons. The undisturbed concordant U/Pb age of 338 m.y. of these zircons thus postdate the magmatic, solidification and mylonitization stage of the rock.
