Geomorphological diversity of peatland basins in the Łódź region and its significance for the accumulation of biogenic sediments

An investigation was carried out on peatlands in the Łódź region. Geological and geomorphological studies focused on 31 sites. The peatland basins are located in moraine plateau and valleys. The diversity of basins in these areas was affected by geomorphological processes: glacial, fluvioglacial, slope, aeolian, thermokarst and fluvial. Peatlands in the region formed in different groups of basins: basins in the moraine area, basins of aeolian origin, basins in valleys (with a distinction between active and inactive valleys). Paleoecological analyses of biogenic deposits show that the peatlands developed from the Late Weichselian to the Subatlantic Period. The schemes of creation and development of the peatlands presented in this study prove a strong influence of geological and geomorphological factors
