Stratigraphy, palynology and radio carbon data of Eemian amd Early Weichselian fluvial deposits in the Drentsche Aa valley system (Drente, the Netherlands)

Abstract

A survey is given of the Eemian and early Weichselian erosional and depositional fluvial history of the Drentsche Aa valley. In between these fluvial deposits four mor-like organic levels are dated on stratigraphical and palynological criteria. The lowest three levels are dated as late Eemian and the Brørup and Odderade Interstadials of the early Weichselian respectively. The fourth mor-like level is dated as middle Weichselian and tentatively called the Papenvoort pollen zone. The fluvial deposits intercalated with mor-like levels are reckoned to be the lower Aa deposits.
