In the Upper Visean-serpukhovion marina sedimentation was restricted to the Central and East iran and in the Bashkirian to the eastern part of the Central Iran. The Visean-serpukhovian-Bashkirian includes Sardar Formation. This Geological formation comprises the uppermost part of the Ozzbak-kuh Group. sandy-shaly facies of the Sardar are rather unigue for the Carboniferous of Iran, which is commonly represented by carbonates. From the type section of Sardar I, have been reported Serpukhovian coral complex comprising Cyathaxonia, Fasciculophyllum, plerophyllum, Soshkineophyllum and Michelinia. From the Sardar I in the shotori Range have been also reported Upper Visean-Serpukhovian genera Ufimia, Plerophyllum, Cyathaxonia Caninia, Amplexus, Amplexocarninia, Pseudowannerophyllum, Minatoa. From the Sardar II have been reported Donetzites, Minatoa and Pseudowannerophyllum, and from the sardar II in Ozbak-Kuh Koninkophyllum, Minatoa, Amandophyllum, Palaeosmilia, Heritschioides, Paraheritschioides, Kleopatriana, Opiphyllum, Fomichevella, Donetzites, Multithecopora. This complex is indicative of the Visean- Serpukhovian-Bashkirian. The Sardar II in the shirgesht area has yieldad Claviphyllum in its lower part. In the Serpukhovian marine sedimentation was restricted to the Central and East Iran and in the Bashkirian to the easterm part of the Central Iran.
