The lithological and petrographic features of the Quaternary deposits in the Warta River valley (Koźmin-North site).
A b s t r a c t. The investigated area is located in the middle section of the Warta River valley, where the Neogen deposits with lignite series occur within the Adamów tectonic graben. In the Koźmin-North excavation, opened for extraction in 2008 and belonging to the "Adamów" Lignite Mine, the Neogene deposits are covered with an about 30-m thick Quaternary series. The research was carried out to identify the origin and age of the Quaternary sediments. As a result, four sandy series and three till series were identified, which were deposited during the South Polish Glaciations and Middle Polish Glaciations. North Polish Glaciations sediments developed in extraglacial conditions.
