Struktury peryglacjalne na stanowisku Łubienica-Superunki (Wysoczyzna Ciechanowska) – wstępne wyniki badań

Abstract: Zarys treści: W zachodniej części piaskowni Łubienica-Superunki, położonej na Wysoczyźnie Ciechanowskiej (północne Mazowsze), stwierdzono występowanie struktur peryglacjalnych, takich jak: inwolucje, bruk peryglacjalny oraz pseudomorfozy po dużych epigenetycznych klinach mrozowych z wypełnieniem lodowo-piaszczystym (ang. composite wegdes). Struktury te wykształcone są w większości bezpośrednio pod współczesną glebą i warstwą piasków pokrywowych o małej miąższości poza jednym z klinów, który występuje w obrębie… Show more

“…The two till beds identified at Łubienica-Superunki in the North Mazovian Lowland and their position indicate that it is the Warthe/Drenthe in the Global Chronostratigraphical Correlation Table for the last 2.7 million years [91], i.e., the Warta and Odra Stadials according to Marks [69] and Marks et al [92]. These beds correspond to two remarkable cold fluctuations of stadial rank [99,100] and were additionally accentuated by a horizon of epigenetic wedges [75] just before the advance of the Middle Polish ice sheet of the Odra Stadial [31,43]. Thus, our current research (Figure 12) demonstrates a clear separation of the two Saalian stadials.…”

“…It is sandy gravel, with a higher proportion of gravel and weaker sorting towards the layer top. In its layer top, Dąbski et al [75] report the presence of a large composite ice-wedge pseudomorph, originally filled with ice and sand. According to those authors, such a location of the wedge indicates long-term permafrost in the icemarginal zone of advancing ice sheet, as interpreted by Frankiewicz [76], and a long break in glaciofluvial deposition at this location.…”
