Die glazifluvialen Sedimente im unteren Günztal (Bayerisch Schwaben/ Deutschland) nach morpho- und pedostratigraphischen Befunden sowie TL-Daten

Stefan Miara and Konrad Rogner

Abstract. Until now in the lower valley of the river "Günz" the glaciofluvial gravel deposits were interpreted as an accumulation of the same glaciation (Riss). But the result of the stratigraphic investigation of loess cover sediments and glaciofluvial gravel layers - in connection with TL (Thermoluminescence)-datings - show that a mindelian gravel body lies beside the gravel deposits of the rissian upper high-terrace. The comparison of both subfaces of the gravel layers demonstrate that the older mindelian gravel deposits can be found on a higher level. Moreover, it is possible to connect the subface of the mindelian gravel with the subface of the "Grönenbach-Schwaighausener" gravel (it is the mindelian gravel of A.

PENCK'S classical subdivision of the Ice Age with four glaciations in the area of Memmingen) in the south of the "Iller-Lech”-region. Furthermore, the stratigraphie division of the aeolian cover sediments at the localities of "Autenried" and "Günzburg" indicates the different ages of both gravel terraces (rissian and mindelian age). In that case the development of both gravel terraces do not belong to the same glaciation; they represent the main gravel deposits of two different glaciation periods.
