Commune: Józefów (pow. biłgorajski, woj. lubelskie)
Framework element or context represented:
Miocene deposits of the marginal part of the Carpathian Foredeep basin.
Primary geological/geomorphological interest:
Sedimentary structures of Badenian organodetritic deposits.
Comparative assessment justification:
The whole complex of the Badenian deposits from the Józefów region, observed in the Józefów and Pardysówka quarries, dips slightly southwards – towards the Carpathian Foredeep. Because most of the layer sets have a concave bottom, it seems that the observed small dips are of an original, sedimentary character.
Protection status and accessibility:
Proposed for protection, well accessible.
Character of site: Quarries
Area: 10 ha
Altitude: 265 m a.s.l.
Lithology: other sedimentary rocks
Discipline: Palaeobiology, Palaeoenvironment, Stratigraphy of Quaternary
Process Age: *all periods
Bedrock Age: Neogene, *all periods
Description of primary interest:
There are two vast active quarries in Józefów, they are called Józefów and Pardysówka, in a range of hills elongated parallel to the southern edge of the Roztocze Hills. Calcarenites with a variable quartz grain content are exposed here. In the Józefów section there are series of channel-like forms of different sizes with a wide range of internal deposits. These forms are orientated N-S, and all dip southwards. In the exposures, the channel-like forms are visible in sections perpendicular to their elongation. Their widths range between 2 and approximately 15 metres, and their depths between 1 and 10 m. Channel-like forms occur at various horizons within the ripple cross-stratified calcarenites. They are filled by deposits that contrast markedly with the underlying sediments. The fills consist of medium- and coarse-grained organodetritic material with numerous intraclasts.
