[en] The revision of the Sautour-Surice geological map revealed some important lateral facies variations in the Frasnian of the Philippeville Massif. Two kinds of lithological successions have been observed, corresponding to the formations newly defined in the Philippeville Massif (proximal facies) and at the southern border of the Dinant Synclinorium (distal facies). The geographic repartition of the two facies is schematically presented. A new section (distal facies) is described from the Hermeton valley (SE of the Philippeville Massif). As a conclusion, the origin of the coexistence of the two facies types in the Philippeville Massif is discussed.
