Conodont succession and biofacies in upper Frasnian formations (Devonian) from the southern and central parts of the Dinant Synclinorium (Belgium) - (Timing of facies shifting and correlation with late Frasnian events)

Early rhenana , Late rhenana and linguiformis Conodont Zones are recognised in the upper Frasnian Neuville, Valisettes and Matagne Formations of southern Belgium, and documented by their index-taxa. The age of the base of the Matagne Formation shifts from the Early and Late rhenana Zones in the southern Dinant Basin into the linguiformis Zone in the more northerly Philippeville Massif. In the first area conodont biofacies analyses reveal a deepening of the shelf below the base of the diachronic Matagne Formation; within the lower part Of the Matagne shales biofacies analyses indicate shallowin...
