Commune: Nowy Sącz (pow. Nowy Sącz, woj. małopolskie)
Framework element or context represented:
Stratigraphy of the Pleistocene in the Carpathians.
Primary geological/geomorphological interest:
Sequence of the Pleistocene deposits.
Comparative assessment justification:
The outcrop represents the standard section of the Carpathian type of loess. Dated sediments and fossil soil indicate the time span from the Sanian Glaciation till the Vistulian Glaciation.
Protection status and accessibility:
Proposed for protection as documentary site after finished exploitation.
Character of site: Artificial outcrop - brickyard.
Area: about 0.5 ha
Altitude: 400 m a.s.l.
Lithology: other metamorphic rocks, sandstones, silts, clays
Discipline: Palaeoenvironment, Stratigraphy of Quaternary
Process Age: Pleistocene, *all periods
Bedrock Age: Pleistocene, *all periods
Description of primary interest:
Pleistocene loamy-dusty deposits covering the rocky socle about 55 m height crop out as the working brickyard called Załubińcze in the northern periphery of the Nowy Sącz town. The steep socle rising over the bottom of Dunajec River is formed with the Eocene Magura Sandstones Formation of the Carpathian Magura Unit. The layer of pebbles 3 m thick composed of Carpathian sandstones and Tatra rocks mainly quartzites occur in the lowermost part of the outcrop in the brickyard. The sequence visible upward is composed of aeolian sediments attaining the thickness of 20 m. These are yellow loams and dusty-loams described as the Carpathian loess and called loess-like loams. They are intercalated with few levels of fossil soil. The age of mentioned sediments was established using the thermoluminescence and paleomagnetic methods. The TL dating indicates a.e. 476±71 ka and 390±58 ka. The lowermost part of loess-like loams corresponds with the Sanian (South Polish) Glaciation and the middle part with the Mazovian Interglacial. Few cycles of aeolian accumulation during the Middle and Upper Pleistocene have been distinguished according to numerous TL dating. The youngest sediments are of Vistulian age.
