Givetian – Famennian, Lb2


Province: 
Libya

Type Locality and Naming

Column: Fezzan Basin

Synonym:


Lithology and Thickness

Repeated cyclothems of ferruginous and gypsiferous claystones, siltstones, and sandstones, which suggest a deltaic depositiona environment, and reworked by storms and tides. The sandstones are frequently cross-bedded. Fossiliferous.


Lithology Pattern: 
Clayey sandstone


Relationships and Distribution

Lower contact

Regionally, the schematic strat column indicates the next older unit as Wan Kasa Fm

Upper contact

Regionally, the schematic strat column indicates the next younger unit as Marar Fm
