Harur Fm base reconstruction

Harur Fm

Period: 
Carboniferous

Age Interval: 
Tournaisian – Visean, Iq3


Province: 
Iraq

Type Locality and Naming

Column: Rutba Uplift (W Iraq)

Synonym:


Lithology and Thickness

Consists of beds of detrital limestone with thin interbeds of black, calcareous, micaceous shale deposited as marine neritic facies (mostly reef and forereef). Upper part is Black shale with sandstone and thin fossiliferous carbonate beds which may correlate to the Sawanet formation in SE Syria.


Lithology Pattern: 
Shallow-marine marl


Relationships and Distribution

Lower contact

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

Upper contact

Regionally, the schematic strat column indicates the next younger unit as Bir El Rah Fm with an unconformity

Regional extent

Equivalent to the Suke Fm, or the Belek formation of SE Turkey. In Syria the Haloul Fm is identical in thickness and facies to the Harur Fm. Black shale with sandstone and thin fossiliferous carbonate beds which may correlate to the Sawanet Fm in SE Syria.
