Bioklasten in het krijt uit boringen van West-en Oost-Vlaanderen

During recent years nearly 500 samples from boreholes drilled in West Flanders have been analyzed (figs 1-3). These samples appeared to contain sufficient amounts of bioclasts (1-2.4 mm) to allow a subdivision into ecozones, which formed the basis of a lithostratigraphic subdivision (fig. 4). The bioclast assemblages indicate that these boreholes are situated outside the depositional area of the Campine-Limburg basin (Maastricht-Hasselt-Antwerp). That is the reason why Arabic numerals have been used in the ecozonation, in distinction with the ecozonation of the Campine-Limburg basin (Roman num... Mehr ...
