Abstract
OUTLINE OF PALAEOMORPHOLOGY OF THE POLISH TERRITORY DURING THE SCANDINAVIAN GLACIATION
Summary
Maximum extents of ice sheets during the eight Pleistocene glaciations are presented against the main ancient and recent landforms of Poland (Figs 1-2). Occurrence of glacial sediments and proglacial ice-dam lakes (within previous interglacial valleys) indicate that advance of ice sheets must have been due to development of glacial streams (lobes). The latter depended on dynamics of ice masses and on landscape in glacial forefields. Most streams seem to have been projecting or surging ones, thus decidedly favouring development of glaciotectonic phenomena. Presented ice sheet extents are obviously asynchronic during each glaciation as pointed out, among others by Kozarski [4] and Marks [14], for the maximum extent of ice sheet during the Wisła Glaciation.
