Early Miocene benthic foraminifera and biostratigraphy of the Qom Formation, Deh Namak, Central Iran
Journal of Asian Earth Sciences, 2007Abstract A total of 165 samples were collected from the Qom Formation investigated in a stratigraphic section north of Deh Namak, in Central Iran. From these, 35 genera and 47 species of benthic foraminifera were identified. The age of the studied section is Early Miocene (Aquitanian to Early Burdigalian) based on the occurrence of Borelis melo ...

Microfacies and depositional environments of the Qom Formation in Barzok area, SW Kashan, Iran
Carbonates and Evaporites, 2018Qom Formation (Oligo-Miocene marine deposits of Middle Iran) in the southwestern Kashan was studied to determine its microfacies and depositional environments. Outcrops of the Qom Formation in the study area with 410 m, consist mainly of limestone, sandy limestone, shale and marl.

Revision of the age of the Qom Formation in the Central Iran Basin, Iran
Journal of Asian Earth Sciences, 2007Abstract The Qom Formation in the Central Iran Basin contains not only relatively abundant calcareous nannofossils and a small number of dinoflagellate cysts, but also a number of stratigraphically significant benthonic foraminifers and ostracods. Calcareous nannofossils reported for the first time from this formation include Coccolithus pelagicus ,

In the Central Iran Basin, the mixed carbonate–siliciclastic deposits of the C member of the Qom Formation were deposited on a carbonate platform which is dominated by rhodalgal associations occurring in tropical–subtropical environment. The biogenic rhodalgal association is dominated by bryozoa, coralline red algae, bivalves and echinoids together ...

Carbonates and Evaporites, 2011
Qom Formation (Oligo-Miocene marine deposits, Central Iran) in the South of Kashan, was studied in order to determine its microfacies and depositional environment. Thirteen microfacies (MF A–M) were distinguished based on petrography, sedimentological features, components distribution and present fauna.

Foraminiferal biostratigraphy of the Miocene Qom Formation, northwest of the Qom, Central Iran
Frontiers of Earth Science, 2017Near Dochah, in the type area of the Qom Formation, Central Iran, the Miocene is partly developed in pelagic facies. From the 894.1 meter thick, ‘a to e’ members of this section, 152 samples were collected. Abundant planktonic foraminifera let us correlate the study section with the global planktonic foraminifera biozonations.

Miogypsinid biostratigraphy in lower Miocene Qom Formation, Central Iran
Micropaleontology, 2019The Qom Formation of Central Iran consists of carbonates, evaporates and clastics in several depositional cycles, divided into nine members in the type area around Qom city, as best exemplified in the Dobaradar section. Each cycle starts with carbonates, followed by terrestrial and finally evaporate deposits.

Burdigalian–Serravalian calcareous nannoplanktons from Qom Formation, North-Center Iran
Arabian Journal of Geosciences, 2009The aim of this study is to determine calcareous nannofossil species found in Kamar-Kuh area and demonstrate this use for biostratigraphic studies. The Qom Formation is widely distributed in Kamar-Kuh section and has nine members(a–f). In this study, 12 samples were taken and prepared with smear slide.

Coupled hydro-mechanical analysis of underground gas storage at Sarajeh field, Qom formation, Iran
Journal of Natural Gas Science and Engineering, 2021Abstract Production or injection of fluids from/in an underground storage site causes variations of pore pressure and stress states. These fluctuations significantly affect implications for hydraulic fracturing, wellbore integrity, top surface subsidence and heave, fault-reactivation, and stability of reservoir and caprock.
