[38] The major results of our investigation can be summarized as follows.
[39] 1. The Anarak section is nowadays the most complete and well-studied among the Gzhelian and Asselian sequences that are known in Iran. The Gzhelian Stage is represented there in a full range; the Asselian, by two lower fusulinid zones. The uppermost Asselian is likely characterized by dolomite facies and lacks fauna.
[40] 2. Despite certain peculiarities, the Gzhelian and Asselian fusulinid assemblages of the discussed section are quite correlative with that from classic East European sections and from sequences located in the Tethian northern margin, namely, in the Carnic Alps, Fergana, and Darvaz. This indicates the occurrence of free connections between the basin in central and eastern Iran and Alborz and the major Paleotethys basin.
[41] 3. The single Gzhelian-Sakmarian (Kasimovian?-Sakmarian) sedimentation cycle is recorded in the territory of Iran. The sediments of the Anarak Group accumulated during that time - continental on the south (Zagros) and shallow marine on the north (central and eastern Iran and Alborz) - overlie the Sardar Group and older deposits and are overlain by the Shirgesht Group with stratigraphic but not angular unconformities.
[42] 4. The attribution of the Shahreza-Abadeh-Hambast region to central Iran is controversial, as the biofacies peculiarities of the Upper Permian sediments distributed there indicate that they are more similar to the synchronous sediments of Zagros than to those from central and eastern Iran and Alborz.
