Paleomagnetism of the Paleozoic Rocks of the Holy Cross Mts (Central Poland) and the Origin of the Variscan Orogen

The Holy Cross Mts are an old, Paleozoic massif, situated close to the Tornquist-Teisseyre Tectonic Zone and structurally incorporated into the Epi-Variscan platform. The area consists of two main units, namely the northern (NHCM) and the southern (SHCM), separated by the west-northwesterly  striking Holy Cross Dislocation. Both regions differ significantly in the history of facial development, continuity of the stratigraphical record, the thickness of rock successions and the history of geotectonic development. An interesting question was whether these differences were also reflected in the paleomagnetic record.
