ABSTRACT.
The authors describe twenty-one Lower Devonian formations from the Vesdre Massif, the Theux Window and the Dinant Synclinorium, in Belgium and France. This work is combined with the geological remapping prograrn of Wallonia (scale 1/25 000). Seventeen of these formations (Fépin, Mondrepuis, Oignies, St-Hubert, Mirwart, La Roche, Pesche, Vireux, Chooz, Hierges, Fooz, Solières, Wépion, Burnot, Marteau, Bois d'Ausse and Acoz) are weIl known frorn the standard literature on the Lower Devonian of the Ardennes and are revised. The Villé and Nonceveux Formations have been introduced more recently, respectively in 1982 and 1992. The Pèrnelle and Hampteau Formations are new. Each formation is presented in a file giving a brief historical account, location of the reference sections, lithology, limits and thickness at the stratotype, lateral variations, age and eventual uses. Furthermore, each formation is documented by the location of the outcrops on a portion of the relevant topographic map (scale 1/10 000) and by a cross-section or stratigraphic log of the stratotype or other reference sections.
