Commune: Modliborzyce (pow. janowski, woj. lubelskie)

Framework element or context represented:
Miocene deposits of the marginal part of the Carpathian Foredeep basin.

Primary geological/geomorphological interest:
Organogenic built-ups of the Badenian formation.

Comparative assessment justification:
The best outcrop of limestone organogenic built-ups of the Badenian formation in Roztocze Hills.

Protection status and accessibility:
Proposed for protection, well accessible.

Character of site: Abandoned quarry.

Area: 3 ha

Altitude: 220 m a.s.l.

Lithology: limestones, marls

Discipline: Palaeobiology, Stratigraphy of Phanerozoic

Process Age: *all periods

Bedrock Age: Neogene, *all periods

Description of primary interest:
It is a big closed quarry, the westernmost of the described sections. It is located in the largest serpulid-microbialite build-up at Roztocze. The build-up, in the present relief, forms an elongate hill just along the Roztocze southern border. A section more than 10 metres thick of serpulid-microbialite limestone is exposed. The build-up overlies uneven surface of Badenian coarse coralline algal carcarenites and marls.
