In the contribution geological structure and geophysical data along the northern part of the Diendorf-Čebín tectonic zone (DCTZ) is analyzed in relation to the position of the measured GPS test areas and precise levelling profiles. For this purposes the former geophysical data have been reambulated and analyzed, too. Revision of geological knowledge and sources has been done in places of the proposed polygons. The results of reinterpretation of the Grav/Mag data and selected seismic reflection profiles suggest new possibilities and variety of structural interpretations of this tectonic zone. It is evident that the whole tectonic system has undergone complicated tectonic development during the Paleogene and Neogene. Therefore the recent mapping and analyses by GPS and precise levelling have to be realized in places where the geological structural ambiguity has to be eliminated., Lubomil Pospíšil, Otakar Švábenský, Josef Weigel and Michal Witiska., and Obsahuje bibliografii
