Weichselian red tills in the Gardno Phase End Moraine (Dębina Cliff) – criteria for distinction, origin and stratigraphic position, and implications for the origin and course of the Baltic Ice Stream

Jaroslaw Jasiewicz
The paper presents the results of investigations of red tills from the South Baltic Middle Sea-Coast recorded in cliff exposures of Gardno Phase End Moraine. Distinctive features of these tills are: high percentage of Aland granitoids and porphyries identified in the 16-32 mm fraction, and large amounts of non-carbonate rocks, mostly red feldspars in relation to quartz, in the sandy fractions of 0,5-0,8 mm and 2-4 mm. Based on structural-textural features, the red till has...
