Sedimentology of the Bieumont Member : influence of the Lion Member Carbonate mounds (Frasnian, Belgium) on their sedimentary environment

peer reviewed ; This is a sedimentological study of Middle Frasnian Bieumont Member fore-reef and off-reef carbonate sediments exposed in the Chimay-Couvin region (Belgium). It is based on four stratigraphic sections: the Lompret quarry, the Frasnes railway section, the Leus quarry and southern parts of the Lion quarry. The Lompret section is here described for the first time and represents the main focus of this work. The Bieumont Member consists of a bedded sequence of argillaceous and bioclastic limestone. At Lompret, the Member is exposed with a thickness of 48 m (the basal contact is not... Mehr ...
