Geo log i cal Quar terly, 62 (1): 48-68, doi: 10.7306/gq.1392 As so ci ate Ed i tor -Wojciech Granoszewski The study was car ried out in the wall of a cliff that formed as a re sult of ero sional cut ting in the west ern fore land of a mo raine landform from the Pom er a nian and Gardno phases (Up per Plenivistulian, Rowy-Ustka clifs; north ern Po land). In di vid ual lithostratigraphic units have been doc u mented: glaciofluvial delta de pos its, Podd¹bie Till, lac us trine-gla cial Wytowno Forma tion (con sist ing of three fa cies: deltaic, lower diamicton, and up per diamicton), lac us trine de pos its of the Orzechowo Forma tion with a thick peat layer, and ae olian se ries at the cliff crest. The Wytowno For ma tion de pos its in clude the fol low ing lithologies: me dium-grained sands, fine-grained sands, muddy sands, muds, silty clays, clays, varved clays, fine-grained multi-frac tion de pos its, and tills (Dêbina Till). Very high in cli na tion of the strata is the re sult of glaciodynamic de for ma tion. The de pos its were ac cu mu lated in a proglacial lake. They are char ac ter ized by mud and clay as well as sand and sand-muddy lithofacies. The vast ness of the wa ter body is ev i denced by a con sid er able size of the delta, and by mas sive struc tures of the clay lay ers.
