Abstract

This study presents the results of a detailed magnetostratigraphic investigation of Early Palaeogene sediments from the NW European Tertiary Basin. Many of the classic sections, including the internationally recognised strato-types for both the Thanetian and Ypresian Stages have been studied. Most of the work has been carried out on the deposits in the London and Belgium Basins, from which the best record of geomagnetic polarity history has been obtained. Work on the succession in the Hampshire Basin has concentrated on clarifying the results from the Whitecliff Bay section, which was proposed by Townsend and Hailwood (1985) as the southern UK Early Eocene magnetostratigraphic type-section. Preliminary magnetostratigraphic investigations have been carried out on the deposits in the Paris and Danish Basins. Although further work on these deposits is required, the palaeomagnetic results, when combined with the existing biostratigraphic data, enable the sequences to be correlated with the geomagnetic polarity time-scale. The work of Steurbaut and Nolf (1986) on the calcareous nannoplankton zonation of the Ieper Clay Formation of Belgium has enabled a high resolution definition of the mangetostratigraphy of the Ypresian Stage. From these data, adjustments to the magneto-biostratigraphic time-scale for the Early Eocene may have to be considered.
