Early and middle pleistocene pollen stratigraphy from British geological survey borehole 81/26, Fladen Ground, central North Sea

Abstract

Eight pollen assemblage zones are identified in a 200 m deep borehole (BH 81/26) from the Fladen Ground in the North Sea (British sector). Pollen stratigraphical data support interpretations of this core based on a previous multidisciplinary study (Sejrup et al., 1987). Pollen zones II to IV, which occur below the Bruhnes/Matuyama boundary, may correlate with the Bavelian complex and possibly include two interglacial stages, while pollen zones V to VIII indicate predominantly cold conditions.
