Lithological description
Greenish grey or dark grey silty shale, often sandy siltstones, with irregular jointing. White mica often present. The siltstones weather with dark or rusty patches of iron and manganese oxides, described as a characteristic shining blue colour on freshly broken surface. No sandstone beds observed. The formation overlays the Sart-Bernard Fm.
Age
Without fossils, tentatively estimated as Llanvirn or early Caradoc, Mid or Late Ordovician.
Thickness
100 to 150 m.
Area of occurrence
Puagne-Sart-Eustache area, in the southern structural unit of the western part of the Condroz inlier.
Type locality
Not defined yet; in the southern part of the Puagne area, south-east of Sart-Eustache.
Alternative names
The “unfossiliferous Basse-aux-Canes shale unit” which was considered as a part of the VitrivalBruyère Fm (Michot, 1934, 1954; Martin, 1969a). The unit resembles slightly the Vitrival-Bruyère Fm, but has no sandstone beds; it is possibly a lateral facies change of (a part of) that formation.
