Der Schwermineral-Gehalt von Saale-zeitlichen Moränen- und Schmelzwasser-Ablagerungen des Münsterlandes

This article is a first summary of the heavy-mineral content of moraine and meltwater deposits of the Saalian glaciation in the Münsterland and its northeastern extension (NW Germany). In the beginning the appearance and distribution of both types of sediments are described (E. Speetzen), then the heavy mineral composition of selected outcrops is reported and the results are compared (D. Henningsen). Generally the predominant heavy minerals are garnet, minerals of the epidote group, zircon, and ordinary hornblende. The heavy mineral contents of moraine sediments sometimes are similar to that of meltwater deposits, in other cases they are different. Obviously there exists no relation between the heavy mineral composition and various advances of the Scandinavian ice sheet and their sediments, the content of heavy minerals rather depends on local influences.
