Kikla and Cabao Fm
Period:
Cretaceous
Age Interval:
Berriasian – Albian, Lb1
Province:
Libya
Type Locality and Naming
Column: Tripolitania and Sirte Basin
Synonym: Chicla Fm, Kabaw Fm
Lithology and Thickness
Also spelled "Chicla" and "Kabaw" formations, this unit has been redefined to include the underlying Chameau Mort Sandstone and a Giosc Shale unit, due to much controversy over an unconformity below the Sidi as Sid formation. Composed of mudstone, sandstones, and conglomerates which were most likely deposited in a braided river system carrying high sediment loads. Cross-bedding is common. Poorly cemented.
Lithology Pattern:
Coarse-grained sandstone
Relationships and Distribution
Lower contact
Regionally, the schematic strat column indicates the next older unit as Tiji Gr (Chameau Mort Sandstone Fm)
Upper contact
Regionally, the schematic strat column indicates the next younger unit as Sidi as Sid and Nefusa Fm
