• Description: Visean conglomerates of the Drahany Uplands contain clasts of granulites, granites and durbachites. Detailed petrological study of granulites enabled to reconstruct their P-T path. U-Pb geochronological dating of the rocks yielded late Variscan ages. The exhumation of the rocks from lower crust to the surface was very fast.
