Results of the preliminary paleomagnetic investigations of some Lower Paleozoic rocks from the Holy Cross Mts (Poland)

Preliminary paleomagnetic data from the south-western part of the Holy Cross Mts (Poland) are presented. Paleomagnetic directions, obtained from the Lower Cambrian (declination = 340°, inclination = 78°), the Lower Ordovician ( D = 198°, I = 74°) and the Upper Silurian ( D = 218°, I =7° or, alternatively, D = 229°, I = 27°) sandstones and greywackes, being compared with coeval paleomagnetic data from the East-European Platform implies 4000 km separation of both regions in the Cambrian - Lower Ordovician lime and their final joining in the Upper Silurian. Paleolatitude similarity of the area under study to the Armorica Plate in the Lower Paleozoic is also suggested.
