Morphotectonic, facies and sedimentary environments study of Ham Formation at Ghaleh mountains, northwest of Takht-e-Jamshid (Fars Province), Iran

The Upper Cretaceous (Coniacian-Maastrichtian) Ilam Formation, that its type section has been studied in simple folded Zagros (12 km south of Ilam city in WSW of Iran), has limitedout crops and different lithofa-cies in Internal Fars province. The facies and sedimentary environments of these outcrops were studied at Ghale mountains, about 25 km northwest of Takht-e-Jamshid. Geomorphologically, the breath-taking view of the landform is due to morphotectonics. The two mountains have much similarity to ancient castles (Iranian Ghale) which tower from the neiboring planar and horizontal plain. The upper parts of the mountains form wall-sided escarpments which are the result of structural and lithological characteristics. Structurally, Ghale mountains are as uplifted synclines which exhibits different axial trends to each other. The outcrops, which were checked up, measured and sampled, consist of two different types of facies, terrigenous (at lower parts)
