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.

Sedimentology and Reservoir Characterization of the Qom Formation, Central Iran Basin
Journal Of The Geological Society Of IndiaABSTRACT The Qom Formation has been considered as a significant reservoir succession in Central Iran forming various hydrocarbon fields. The geological data from four wells from the two hydrocarbon fields (I and II) have been investigated for a reconstruction of sedimentary and diagenetic environments as well as reservoir quality of the ...

The Qom Formation deposits, located at 12 km southeast of Salafchegan (N: 34° 21′ 26″ and E: 50° 32′ 14″), have a thickness of 110 m. The formation includes thin, and medium-to-thick bedded limestone, as well as shale, overlying the Lower Red Formation (early Oligocene) above an erosional unconformity.

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

Abstract This research attempted to reconstruct the sedimentary environment and depositional sequences of the Qom Formation in Central Iran, using biofacies and taphofacies analyses. The Qom Formation in the Andabad area (3°48′12.6″ N, 47°59′28″ E) is 220 m in thickness. The thickness of the Qom Formation in the Nowbaran area (35°05′22.5″

The Early Miocene Qom Formation depositional setting; Northwest of Central Iran Basin
2021An outcrop of the Qom Formation (Fm.) is considered to determine the depositional setting model in the northwest of Central Iran. Field observations show that the Qom Fm. is composed of thin to thick-beds limestone along with alternation of green marl and argillaceous limestone.

Abstract The Qom Formation is deposited along more than 1800 km of the NE margin of the Tethyan Seaway in the Oligocene-Early Miocene during the final sea transgression on the Iranian Plate. We present (foraminiferal-based) biostratigraphic data from three exposed sections near the northwestern Jazmurian Lake, as the southeasternmost ...

An early Rupelian origin of Titanoderma pustulatum recorded in the Qom Formation, Iran
2019The Rupelian Uromieh section of the Qom Formation consists of Nummulites-bearing limestones that overlay thick polymictic conglomerates and are overlaid by marlstones rich in planktonic foraminifera. The section was analyzed with the aim to provide a first description of its still unknown coralline algal assemblages, and for depicting its benthic ...
