Temporal and spatial distribution of the Qom Formation pyroclastic deposits with special emphasis on SE Kerman Province: Their application in (tephra) event stratigraphy [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2022 This article is the first published example of the application of (tephra) event stratigraphy in the Qom Formation as well as the temporal and spatial distribution of the Qom Formation pyroclastic deposits. The presence of igneous (volcanic) associations

Biostratigraphy and Microfacies of Qom Formation in Urumieh – Dokhtar Zone, Iran [PDF]
International Journal of Engineering and Technology, 2018 In order to determine the accurate paleoenvironmental conditions of Qom Formation, one stratigraphic section was studied in the Urumieh-Dokhtar Zone (West of Ashtian). 60 thin sections of the Qom Formation, 71 m thick, were prepared and the distribution of benthic foraminifera was analyzed.

Reconstruction of the depositional sedimentary environment of Oligocene deposits (Qom Formation) in the Qom Basin (northern Tethyan seaway), Iran [PDF]
Geologos, 2020 Abstract During the Rupelian–Chattian, the Qom Basin (northern seaway basin) was located between the Paratethys in the north and the southern Tethyan seaway in the south. The Oligocene deposits (Qom Formation) in the Qom Basin have been interpreted for a reconstruction of environmental conditions during deposition, as well as of the ...

The role of fossils in the microfacies studies and recognizing the sequence boundaries of the Qom Formation: A case study in Ghasr-e-Bahram Section, northwest part of Siahkuh, south Garmsar [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2023 Sequence stratigraphy is a branch of stratigraphy that can enable us to correlate deposits with considerable accuracy. This research aims to investigate the role of fossils in the recognition of system tracts and sequence boundaries along succession ...

Application of elemental data in reconstruction of paleoredox conditions of the Qom Formation at Khani Abad section, southeast of Kashan [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2018 Introduction The abundances of minor-elements in carbonate rocks depend on the noncarbonate materials, including detrital minerals, accessory authigenic precipitates, noncarbonate skeletal material, organic matter, phases formed during diagenesis and the

Geoscience Frontiers, 2015 AbstractThe Oligocene–Miocene Qom Formation has different depositional models in the Central Iran, Sanandaj–Sirjan and Urumieh-Dokhtar magmatic arc provinces in Iran. The Kahak section of the Qom Formation in the Urumieh-Dokhtar magmatic arc has been studied, in order to determinate its microfacies, depositional model and sequence stratigraphy.
