Late Saalian and Eemian Interglacial at the Struga site (Garwolin Plain, central Poland)

Abstract The paper reports pollen analyses of 47 samples from palaeolake sediments at WH-15 Struga near Puznówka on the Garwolin Plain in central Poland. The pollen succession covers Late Saalian (MIS-6) and fully developed Eemian (MIS-5e) successions. The Late Saalian section is well developed (more than 2 m thick) and contains sub-zones reflecting the alternating dominance of steppe-tundra and boreal forest communities. The analysed Eemian succession is an uncommon succession described as a variant with early appearance and culmination of Tilia. In these terms, the successions of WH-15 Struga resemble those of sites of the Eemian interglacial known from the vicinity of Warsaw: Błonie, Warszawa-Żoliborz and Warszawa-Wola. The WH-15 Struga site is one of several recently discovered fossil sites of Eemian lakes on the Garwolin Plain, constituting the southern fragment of the extensive Eemian lakeland in the Polish Lowland.
