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.

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 ...

Environmental Earth Sciences, 2017 To estimate uniaxial compressive strength of some sedimentary rock types from a set of index test results, selected soft computing methods were employed. Consequent comparative performances of these methods were also evaluated. Some selected sedimentary rock types (i.e., grainstone, wackestone–mudstone, boundstone, gypsum and silty marl) collected from

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.

Benthic Foraminiferal Events of the Qom Formation in the North Central Iran Zone
Paleontological Research, 2019In order to recognize and verify the lower Miocene deposits and the Aquitanian-Burdigalian boundary, benthic foraminifera from different localities in the north of the Central Iran Zone are considered. These facies-controlled foraminifera are useful for biostratigraphical studies, especially in the absence of planktic foraminifera.

Depositional environment of the evaporitic unit (D-member) of the Qom Formation (Central Iran)
Carbonates and Evaporites, 2007The Qom Formation, in the Central basin of Iran, is characterized by shallow marine limestone and lagoonal facies. The D-member, one of the six major members of the Formation, is dominated by gypsum (anhydrite). Several types of textural and structural features have been recognized in this unit.

Sea cows are exceptional fossil vertebrates recently discovered in the deposits of the Qom Formation. Yet, the Sirenia-bearing limestones are still poorly understood in terms of detail paleoenvironmental and micropaleontological investigations. In order to distinguish the temporal and paleoenvironmental context of the Sirenia (sea cow) bearing deposits
