Drumlinkerne, ältere Würmschotter und das Würm-Interstadial-Profil von Hörmating/Obb.

Abstract. Several new gravel pits have been opened near Rosenheim in the formerly glaciated foreland of the Alps in Bavaria. Some new observations could be made in the centre of the Inn-Piedmont Glaciation area. There has been no „Stephanskirchen Stage" during the retreat of the Würm glacier. Instead of endmoraines, near Stephanskirchen, Laufen gravel deposits covered by boulder clay of Main Würm Glaciation are found. Some Inn drumlins, not so well shaped and streamlined as elsewhere, contain cores made up from different Laufen Interstadial deposits, especially from this same Laufen gravel. There is developed one outstanding „Middle Wurm" (Woldstedt 1958) profile in a drumlin near Hörmating (Ostermünchen-station on the line Munich—Salzburg). In the southern end of this drumlin and in its Laufen gravel core is to be seen a lacustrine intercalation with a small peat layer very much compressed and dated Gro 45 300 ± 1000 years B.P. In the northern end of the Hörmating drumlin on the same level, there is a thoroughly weathered decalcified gravel zone developed, representing Göttweig Interstadial interval. The beginning of this Göttweig weathering can be fixed by now (44 000—42 000 years before today). Göttweig Interstadial is identic with Laufen Interstadial of A. Penck. There is another weathered zone (Paudorf Interstadial?) on the top of the gravel layer and beneath the covering boulder clay, this latter belonging to Main Würm Glaciation.
