Sedimentary environments, conodont biofacies and paleoecology of the belgian Famennian (upper devonian) - an approach

The vertical succession of the sedimentary formations, which are diachronic with respect to the standard conodont and other microfossils zonation, represents a regressive megasequence in the Belgian Famennian, ranging from relatively deep, offshore open marine, shallow nearshore, to backshore restricted marine environments (THOREZ et al ., 1977). Different associations of platform conodont form genera (Biofacies) reflect different ecological conditions, which are directly or indirectly related to water depth, turbulency, salinity and proximity to the coast ; from offshore to backshore we recog...
