Carboniferous sediments in the Asad-Abad section (Shahreza city, South-east of Isfahan), consists of much more carbonates beds, and includes abundant corals. In this study, have been identified 3 coral beds from Late Carboniferous that have 4 Species belonging to 4 genera of rugose and tabulata corals. These corals including: fasciculate rugose colonies of Paraheritschioides cf. antoni minor and Heintzella sp., tabulata fasciculate colonies of Multithecopora sp. and solitary rugose of Siphonophyllia sp. There are the colonial corals in 2 horizons to Patch-reef form. The solitary corals in the last coral bed are a dense assemblage and made a boundstone. Based on these faunae the coral horizons are Late Carboniferous (Late Serpukhovian-Bashkirian) in age.
