Early-Middle Frasnian (early Late Devonian) sedimentology and magnetic susceptibility of the Ardennes area (Belgium): identification of severe and rapid sea-level fluctuations

This paper focuses on the early and middle Frasnian stratigraphic interval from the Ardennes area in Belgium, with a multidisciplinary and high-resolution study, including detailed sedimentology and magnetic susceptibility study, to identify the main paleoenvironmental changes affecting this interval. Three mud mound levels are observed, in stratigraphic order, the Arche, La Boverie and Lion mounds, surrounded and separated by shales. The three mounds are characterized by the same facies and relatively similar facies evolution through time. The base of the mounds shows deep mound facies (mud,... Mehr ...
