According to common interpretations, two narrow crustal blocks are supposed to occur on the south-western edge or in the foreland of the East European Craton. The first one, bounded on the NE by the Nowe Miasto-Radom-Rava Ruska fault system, and on the SW by the Holy Cross Fault, stretches NW-SE from the Łysogóry-Radom region in Poland to the Rava Ruska Zone in Ukraine. The second one, bounded on the NE by the Holy Cross Fault, and from the SW by the Chmielnik-Ryszkowa Wola–Krakovets fault zone, is thought to tie together the Kielce area of the Holy Cross region with the Kokhanivka Zone in Ukraine. Both these blocks may have formed in connection with the development of regional listric faults during Precambrian asymmetric stretching of the Baltica continent, and were part of the marginal zone of the East European Craton. The sedimentary development of the blocks can be comparable to the Blake Plateau off the Florida coast. Both the Paleozoic sections and tectonic deformation styles in the Polish and Ukrainian segments of these blocks are different. Paleozoic tectonic structures of the Holy Cross region have a southern vergence, while the Paleozoic rocks of the Rava Ruska and Kokhanivka regions in western Ukraine are thrust towards the NE. This demonstrates the different tectonic evolution of the Paleozoic succession between the Holy Cross region and western Ukraine, and makes questionable the genetic relationships between these two regions. In this situation, the tectonic blocks of the foreland should be considered heterogeneous. Structural-facies evidence suggests that the SW boundary of the East European Craton should be moved at least to the Chmielnik–Ryszkowa Wola-Krakovets fault.

Composite tectonic structure of the Holy Cross Mountains originated as a result of multiple tectonic movements dating from Cambrian till Quaternary. The movements had different intensity in the northern (Łysogóry Block and southern (Kielce Block) parts of the area. The Caledonian and Variscan movements formed the fault-block structure with prevalent WNW–ESE directions, while the Alpine movements — disrupted the older units with transpressive slip translocations along already existing longitudinal faults. All the deformations occurred within an anorogenic area — a sinking, fragmented margin of the East European Platform.

The article presents the cross-border cooperation of geologists from the Lower Silesian Branch of Polish Geological Institute and the national geological surveys of the Czech Republic and Germany. The current cooperation is discussed on the basis of Geological Map Lausitz–Jizera–Karkonosze as well as on geological research of the Muskau Arch. The Geological Map Lausitz–Jizera–Karkonosze, in 1 : 100,000 scale, with Comments, presents the geology of the north-western part of the Bohemian Massif. A short geotectonic evolution of the area from Neoproterozoic to Cenozoic is presented. The results of Polish-German geological research and inventory of so-called “geotopes” are the basis to establish a cross-border Muskau Arch Geopark.
