The late Weichselian in Halland, Southwestern Sweden: A pollen‐analytical study

Abstract

Late Weichselian sediments from six sites in southern Halland were pollen analysed in order to investigate the vegetational and climatic development, with special regard to the complex late‐glacial history in the area. The vegetational history is outlined, covering the time period c. 13,000–10,000 BP. The development in southern Halland from a herbpredominated Older Dryas phase to the Holocene, shows high degree of uniformity between the studied sites. Betula‐maxima below the Older Dryas interval make a division into B⊘lling and Aller0d interstadials possible. Organic production reached its Late Weichselian maximum during the late Aller⊘d. The Younger Dryas interval indicates only moderate climatic deterioration. Pollen concentration has proved a useful parameter, and has allowed estimation of annual pollen influx during the Late Weichselian. Several ¹⁴C‐dates are presented; they are however not sufficient to establish a regional chronostratigraphy. The relation between the observed sedimentological and biostratigraphical features in southern Halland and ‘anomalous’ events, such as glacier advance(s) and/or a transgression, are discussed.
