The Biesenthal Basin formed by thawing of dead ice, is located at the northern rim of the Bamim Plateau north of Berlin; in it sedimentary processes varied considerably during the Late Weichsel Glacial Period. Their variations are reflected in sedimentary fabrics, grain size distributions and repeated overprinting of surface textures on quartz grains. The glacifluviolimnic, Iimnic and aeolian sediments were deposited on the shore of a periglacial water within the area shaped by the last glacial advance; presently it is located at the border between lowlands and plateau. The sedimentary sequence is characterized by variations and deformations at the scale of micrometers, hence the present study focussed on microfabric analysis.
