Przedmetamorficzne stylolity w dolno paleozoicznych utworach węglanowych rejonu Zawiercia (NE obrzeżenie GZW)
Abstract
PREMETAMORPHIC STYLOLITES IN THE LOWER PALEOZOIC CARBONATE DEPOSITS OF THE ZAWIERCIE (SW POLAND)
Summary
Two generations of the pre-metamorphic stylolites have been observed in limestones and marbles of the Ordovician-Silurian carbonate sequence. Older stylolites formed before folding or at the earliest stages of folding. Younger stylolites formed after folding of carbonates due to vertical stress cuased by uplift of fragments of the crystalline basement of the Kraków - Myszków fault zone. Orientation of the younger stylolites suggest that the NE part of the Kraków-Myszków fault zone was uplifted. The formation of stylolites brought about shortening of the Lower Palaeozoic carbonate sequence by 0,7%. Both generations of stylolites were affected by the contact metamorphism
