| contents | This detailed pollen record represents the accelerator mass spectrometry dated Last Glacial Maximum sediment core section (Och18-II-4) from Lake Ochaul (54°14'N, 106°28'E; 641 m a.s.l.). The lake is situated in Eastern Siberia, ca. 100 km northwest of Lake Baikal. Altogether, 40 samples from the 160-cm-long core section have been treated using dense media separation to extract pollen and non-pollen palynomorphs for further microscopic analysis. The results show that non-arboreal pollen dominate throughout the record (mean value ca. 92.6%), however, pollen of boreal tree and shrub taxa including Betula sect. Albae (0.6–4.8%), Picea (0.6–2.8%), Pinus sibirica (Haploxylon type) (up to 1.5%), Pinus sylvestris (Diploxylon type) (up to 2%), Larix (up to 0.6%), Abies (up to 0.6%), Betula sect. Nanae/Fruticosae (2–5.2%) and Salix (up to 3.2%) continuously present. |
