Taberia Formation

Taberia Fm

Period:

Devonian

Age Interval:

Upper Devonian; Frasnian-Famennian (1)

Province:
Iullemmeden Basin - Tim Mersoï Sub-basin

Type Locality and Naming

Joulia, 1959; Claret & Tempère, 1968.

References: Lessard, 1961; Claret & Tempère, 1968; Dars et al., 1971; Valsardieu, 1971; Termier et al., 1973; Fabre et al., 1983; Fabre, 2005.

Synonym: Grès d’Amesgueur (Joulia, 1959); Grès de Taberia (Claret & Tempère, 1968);

Lithology and Thickness

Coarse to fine sandstones locally gypsiferous, and lagoonal shales with rare bivalves (Valsardieu, 1971). Claret et al. (1968) state that except for a coarse-grained base, the sandstones are fine and intercalated with siltstones and shales with rare trace fossils Spirophyton (Fig. 1). Thickness: 80 – 150 m. On page 51 of Valsardieu (1971), it is stated a thickness of 80 m for this Formation in the area of Touaret town.
