Znaczenie warunków geologicznych i geomorfologicznych dla rozwoju i współczesnego stanu torfowisk Niecki Nidziańskiej

Abstract

A b s t r a c t. Synthetic studies of biogenic deposits made on a regional scale reveal how the geological structure and land relief have been affecting the development of limnic and peat sediments. The research was made in the Nida Basin, which is the region of great diversity of natural landscape in southern Poland and has a relatively large area of peatlands. The conclusions have been based on SRTM interpretation, hydrogeological documentations of deposits near Busko-Zdrój, and field and laboratory works. The spring-fed fen at Zwierzyniec, along with the fen at Miku³owice, has been forming on the densest complexes of alkaline fens in the Ma³opolska Upland. The calcareous tufa includes records of chemical denudation occurring in the southern part of the Piñczów Hump in the Late Weichselian and Holocene.

Bedrock characteristics of selected covered karst sites in the Małopolska Upland

“…Urban (2015) writes about the multiplicity of concave forms associated with covered karst in Niecka Nidziańska. Most of these forms are dry karst funnels, though, as indicated by Okupny and Jucha (2020), some have filled with biogenic sediments, and peatlands have formed within them. This is the case at, for example, the Gaik-Winiary site.…”

Transformation of treeless depression wetlands in Central Europe over the last 100 years: Włoszczowa Basin (southern Poland) case study

“…The region is also characterised by a high rate of peat occurrence, at 8%. Some 160 mires of various types are located in the area, covering a total of 21,000 hectares (Okupny & Jucha, 2020). Most of them are mires associated with the valleys of rivers (mainly the Pilica River) and watercourses.…”

Geochemical characteristics of Late Glacial and Holocene biogenic sediments in central Poland and implications for reconstructing the palaeoenvironment

“…Then, the spatial distribution of these indicators was examined in the catchment areas in the studied region using raster zonal statistics tools. A detailed description of the assumptions and the possibility of using the calculated indices can be found in the works of Migoń and Kasprzak (2014) and Okupny and Jucha (2020). The geochemical landscapes were distinguished into autonomous, transit and accumulation landscapes on a regional scale using the procedure proposed by Sołowiej (1987) and Rycharski and Piórkowski (2001).…”
