    Resumé

    Mudstones from the Nuussuaq Basin, onshore West Greenland (figs. 1, 2) yield calcareous nannofossils. The dating of these mudstones using nannofossils and dinoflagellate cysts has enabled a detailed Lower Paleocene biostratigraphic zonation to be established. Samples from four onshore wells and three outcrop sections yield low abundance and low diversity assemblages and date the youngest mudstones as Late Danian, upper nannofossil zones NP4 -?lower NP5 (MARTINI 1971), correlating with NNTp5B (VAROL 1998). The nannofossil data and complimentary palynological dating not only allow a relatively accurate dating of the sediments deposited in the Early Paleocene, but along with published 40Ar/39Ar and magnetostratigraphic data provide more rigorous constraints on the timing of the initiation of volcanism onshore West Greenland and the North Atlantic Igneous province.
