Graphic correlation of Frasnian sections (Upper Devonian) in the Ardennes, Belgium

A high-resolution correlation of 10 Frasnian sections in the Belgian Ardennes is made using the graphic correlation method. The measured ranges of 85 conodont taxa, 48 coral taxa. 29 brachiopod taxa and one stromatoporoid taxon have been assembled into a chronostratigraphic framework. The Ardennes Frasnian Regional Composite developed in this study provides a higher stratigraphic resolution than the traditionally used conodont zonation. It allows a subdivision of the Frasnian into 532 composite standard units derived from the standard reference section in the southern part of the Dinant Syncli... Mehr ...
