Early Pleistocene Tiglian sites in the Netherlands: A revised view on the significance for quaternary stratigraphy

The Tiglian-A, B and C form the main subdivision of the Early Pleistocene Tiglian Stage in Northwest European chronostratigraphy since the 1960's. We re-evaluated the sedimentary context and new and legacy pollen assemblages of the classic type localities of these Tiglian pollen zones in the Dutch-German border area and Roer-Valley-Graben. Following recalculation of new upland pollen sums, we found that the three-fold subdivision of the Tiglian Stage is too simplistic and lacks a sound stratigraphic basis. The Tiglian-A is only found locally and cannot be positively identified in the RVG. The... Mehr ...
