Elongated hills near Schonhorst, Schleswig- Holstein: Drumlins or terminal push-moraines?

Examination of bore-holes, test pitting and surficial mapping of one hiII belonging to the group of smooth, elongated hills by Schonhorst, Schleswig-Holstein reveals three geological units: the lower, fine-grained, massive and compact till; the glaciofluvial sand; and the upper, coarse-grained, compact tiII with minute stringers and lenses of sand and silt. The sequence is strongly glaciotectonically disturbed. A detailed analysis of thin sections of the till micro-fabric, and of radiographs from undisturbed, onented cores shows a relatively strong NE-SW and NW-SE particle orientation in the lower till and a weakly clustered to random orientation in the upper till. It is suggested that the field represents either drumlins (the more favourable hypothesis) or terminal push-moraines, formed dunng the first three ice advances of the Weichselian Glaciation
