Exaration phenomena at the terminal icesheet parts of the Middle-Polish Glaciation along the northern slopes of the Central Polish Uplands

Abstract

The glacial erosion in the maximum extent zone of the Middle-Polish (= Odranian, = Riss I) Glaciation in the Central Polish Uplands resulted in the incorporation of local material into end-morainic sediments, formation of polished surfaces, roches moutonn¾es and exaration moraines with a chaotic arrangement of local debris. The maximum icesheet extent can be recognized not only by the presence of the Scandinavian material and geomorphologic evidence but also by the results of glacial erosion processes.
