“…This process generated skeletal and non-skeletal accumulations across the homoclinal ramps. Peloidal grainstones-packstones formed through storm-induced abrasion along the shoreline (e.g., figure 8c in Sardar Abadi, Kulagina, Voeten, Boulvain, & Da Silva, 2017).…”

“…Although sedimentologic evidence of algal and mud mounds are frequently reported along carbonate platforms throughout the earliest Mississippian (e.g., Webb, 2005), evidence for such mounds is scant across the Mobarak Formation. The highly dynamic depositional history of the Alborz Basin during Early Mississippian times rendered these environments very sensitive to storm agitation, which has been extensively documented in the Mobarak Formation (Sardar Abadi et al, 2015;Sardar Abadi, Kulagina, Voeten, Boulvain, & Da Silva, 2017), including in the Jaban section also studied by Zandkarimi et al (2019). The recorded storm-dominated depositional regimes are sedimentologically incompatible with the "sheltered depositional environment" and its inferred…”

New interpretations of depositional palaeoenvironments in the Mississippian (Lower Carboniferous) Mobarak Formation (Alborz Mountains, Iran) suggest a significant and persistent influence of storms. This deviates from previous conclusions that these deposits recorded mounds, patch reefs, and extensive lagoons deposited under stagnant environmental conditions. We here clarify and discuss the origin and nature of this misconception by explaining "unexpected" observations that are informed by outdated interpretations of the depositional environment of the Mobarak Formation. This evaluation offers the context required for appropriately interpreting and correlating Mississippian depositional records across the Alborz Basin.

“…Sardar Abadi et al (2017) investigated the Early Carboniferous foraminiferal assemblages of the Mobarak Formation in the Alborz Basin, Iran. Ivorian foraminiferal proliferation follows a cyclic pattern; a first cyclic episode was followed by two distinct pulses of second proliferation and diversification.…”

“…The Mississippian shows a transition between early Palaeozoic stable warm and greenhouse conditions to more late Palaeozoic oscillating climates, including several major glacial episodes (e.g. Powell 2005Powell , 2007Kammer and Ausich 2006;Montanez et al 2007;Mullins and Servais 2008;Heim 2009;Lowry et al 2014;Sardar Abadi et al 2017).…”

A relatively complete conodont record from Famennian to the Mississippian/Pennsylvanian boundary was investigated in the Anarak section, Central Iran. The studied interval belongs to the Bahram, Shishtu, Ghaleh and Absheni formations. The Famennian part of the section (Bahram Formation) ranges from the Palmatolepis triangularis Zone into the Bispathodus ultimus Zone. Not all conodont zones could be defined due to the lack of indicative species. Furthermore, it seems likely that a hiatus occurs around the Devonian/Carboniferous (D/C) boundary (most probably from the Siphonodella praesulcata to the ?Siphonodella sulcata–early Siphonodella crenulata conodont zones) based on the lack of stratigraphically important conodonts as well as on sedimentological criteria. The lack of representative siphonodellids and protognathodids at the base of the Mississippian prevents detailed stratigraphic position of the D/C boundary. Lower Carboniferous (Mississippian) rocks are characterized by red nodular limestone which is unique in comparison with other studied sections of the same age in Central Iran. Within the studied section, we could define the Mississippian/Pennsylvanian boundary. The mid-Carboniferous boundary was defined by the occurrence of Declinognathus noduliferus s.l. Conodont biofacies changes (Mississippian genera Gnathodus and Lochriea have been replaced by Pennsylvanian genera Declinognathus and Idiognathodus) are recognized in this section as well.
