Upper Carboniferous lithostratigraphic units (Belgium)

open access: yesGeologica Belgica, 2002
Upper Carboniferous, Namurian to Westphalian coal measures in Belgium form part of the Variscan Foredeep in northwestern Europe, with maximum preserved thickness over 3500 m. Despite post-depositional separation of the Wallonian and Campine coal basins by the Brabant Massif and different tectonic styles, a common lithostratigraphic nomenclature can be ...
