Wapiennik Breccia Member (Pieniny Klippen Belt, Poland) - revised stratigraphy and origin

Arabas A., Sidorczuk M., Olszewska B.

Geological Quarterly

2011

Vol. 55, No. 1

49-62

The Wapiennik Breccia Member was originally attributed to the Czorsztyn Limestone Formation of the Czorsztyn Succession in the Pieniny Klippen Basin. The breccia was assigned previously to the Callovian-Oxfordian. Based on micropalaeontological and microfacies studies we have determined its age as late Albian. At this time the Czorsztyn Swell was affected by extensional faulting, with subsequent submarine erosion of scarps. The re-evaluated age of the breccia, as well as the lithology of its clasts and its matrix that contains Cretaceous foraminifera, indicate the assignment of the Wapiennik Breccia Member to the Chmielowa Formation.
