EARLY AND MIDDLE PLEISTOCENE POLLEN STRATIGRAPHY FROM BRITISH GEOLOGICAL SURVEY BOREHOLE 81 29, DEVILS HOLE AREA, CENTRAL NORTH-SEA/

The palynomorph content is described of Early and Middle Pleistocene s ediments from a 140 m deep borehole (81/29) from the Devils Hole area, central North Sea. The Early Pleistocene sequence in 81/29 is interpr eted as predominantly of Bavelian age and is correlated with an existi ng Fladen Ground stratigraphy; it also supports a previous foraminifer al correlation. The overlying Middle Pleistocene sequence contains a c limatic amelioration of interstadial or interglacial status. Pollen as semblages from Saalian sediments in the uppermost part of the core ind icate that the site of 81/29 received a strong influx of reworked mate rial of British origin.
