PALEOMAGNETISM OF CARBONIFEROUS SEDIMENTS FROM THE WEST SUDETES (SW POLAND)

The studied Carboniferous flysch and molasse sediments from the Intra- Sudetic Basin correspond to the period from Middle Visean to Early Aut unian. Main magnetic minerals carrying the natural remanent magnetizat ion (NRM) are goethite, magnetite, maghemite and hematite, all usually secondarily formed and/or remagnetized due to several tectonometamorp hic events. In most samples several NRM components were isolated. One of them is usually a Jurassic-Triassic overprint. Some others define t he Westphalian-Early Permian segment of the declination and inclinatio n trajectory for the Sudetes calculated according to the reference app arent polar wander path for the Baltica plate. The Sudetic path is sli ghtly shifted to the east compared to the reference path, suggesting t he possibility of independent movements of the Sudetes during this tim e. The majority of isolated NRM components are secondary and related t o the Sudetic orogenic phase and later tectonometamorphic activity.
