| Location | Dinant synclinorium, Ardennes, Belgium |
The Aye Formation is a geologic formation in the Dinant synclinorium, Ardennes, Belgium. It is part of the Condroz Group, [1] at the base of the middle Famennian (Upper Devonian). It is characterized by the presence of a conodont fossil Palmatolepis rhomboidea. [2]
It is composed mostly of greenish shales and siltstones with some lenses of sandstone. As it formed in an offshore position, in a subtidal wave-influenced environment, bioturbation features are significant. Cross-bedding structures also occur. [2]
The stratotype is located in the area of Houyet and Aye in Belgium. [2]
