Description of primary interest:
Next geosite of Roztocze is the disused quarry on the Krzyżowa Góra Mountain, close to Nowiny village. A continuous succession of the Upper Badenian sandy calcarenites, with a thickness of ca. 15 m is exposed here. The lower, less diversified part of the exposed succession consists of alternating, apparently massive layers of calcarenites and of horizontally laminated, fine-grained calcarenites with an admixture of quartz and glauconite. In thicker, apparently massive layers, tabular cross-stratification is visible. In the western part of the quarry, about 100 m from the main wall, a distinctive set of sediments, up to 6 m thick, is visible over an area of about 200 m. It rests with a sharp, erosional boundary on the rocks of the described section. It is characterised by poor lithification and by poor sorting of the detritic material. It contains common oyster shells, quartz grains, fragments of black flints and clayey-marly intraclasts. The intraclasts have a diameter of up to 50 cm.
