Abstrakt (anglicky)
   Samples from three tectonic levels of sedimentary rocks affected by contact/periplutonic metamorphism of the Žulová Pluton are described 1/ HT/LP-MP ?normal? metasediments and metavolcanics of the ZP mantle. The P-T conditions estimated correspond to 720-800 °C in migmatite zone, and 650-744 °C outside migmatite zone (at 4 Kb) 2/ HT/LP ?exotic? gneiss preserved tectonically at the Marginal Sudetic Fault, containing an assemblage: Qtz + Plg + Bt + Ms + St + And + Crd + Grt + Sil + Sp + Ilm; P-T conditions 568-690 °C and 2-3 kbar. The mineral assemblages and P-T conditions calculated indicate that the rock represents an upper part of contact aureole of the ZP which was in other places completely removed by erosion. 3/ LT/LP metasediments of the Branná Group close to MSF. The presence of andalusite + cordierite provides evidence that these rocks were also affected by ZP intrusion at least in the vicinity of the MSF.
