Abstract
Tunnel valleys of old glacial landsystems in Poland
Highlights
Tunnel valleys belong among the largest erosional structures of the Pleistocene cover of the Polish Lowland and other areas around the Baltic Sea [1]
They occur on other continents, the largest number of them were recognised within the extent of Pleistocene glaciations in the Northern hemisphere
In the old glacial landscape areas in Poland, which were shaped during the Saanian (Elsterian, Middle Polish Glaciations), Odranian (Saalian I), and Wartanian (Saalian II) Glaciations, outlines of tunnel valleys have been obliterated in the landscape
Summary
Tunnel valleys belong among the largest erosional structures of the Pleistocene cover of the Polish Lowland and other areas around the Baltic Sea [1]. They occur on other continents, the largest number of them were recognised within the extent of Pleistocene glaciations in the Northern hemisphere They were formed during pre-Pleistocene glaciations: Neoproterozoic, Ordovician (Hirnantian), and PermoCarboniferous. In the old glacial landscape areas in Poland, which were shaped during the Saanian (Elsterian, Middle Polish Glaciations), Odranian (Saalian I), and Wartanian (Saalian II) Glaciations, outlines of tunnel valleys have been obliterated in the landscape. In these areas, no trough lakes have been preserved whatsoever – so characteristic within the extent of tunnel valley occurrence in the area delimited by the Late Vistulian glacial maximum (LGM). The aim of this study was to develop a synthetic representation of the occurrence of documented or highly probable forms of the tunnel valley type in zones of various age of the old glacial landscape of the Polish Lowland and the uplands of Southern Poland, as well as to obtain data which support palaeogeographic reconstructions with regards to both the course of glacial events and later landscape transformations under different conditions of changing environment
