Carboniferous sequences of the Baluchestan Basin, Central Iran and Alborz are correlated. Distribution of corals in the Lower Carboniferous of Iran is influenced by both regional and world transgression and regression episodes. Tournaisian- Middle Serpukhovian marine deposits are well-developed and rich in fossil corals in the Alborz, and Baluchestan. They are extended from southeast to northwest in the area of Lower Carboniferous deposition. In the Middle Serpukhovian-Gzhelian marine sedimentation was restricted to the East Iran (Tabas area). However, fossil evidence suggests Late Carboniferous age only for part of the Tabas area sequence.
