Biostratigraphy of the Carboniferous deposits of the Świdnik blocks (Lublin Coal Basin)

Abstract

The sequence of the Carboniferous deposits pierced by a series of boreholes within the Świdnik blocks near Lublin in eastern Poland (Lublin Coal Basin) begins with the Upper Vis¾an strata and continues to the Lower Westphalian. The goniatite content is used for biostratigraphic subdivision of these strata and it evidences the paralic conditions ranging until the Gastrioceras subcrenatum Zone of the lowermost Westphalian.
