Sedimentary facies and paleoenvironmental interpretation of the Oligocene larger-benthic-foraminifera-dominated Qom Formation in the northeastern margin of the Tethyan Seaway

Palaeoworld, 2020
The well-exposed outcrops of the Bujan, northern Abadeh, and Varkan stratigraphic sections of the Qom Formation in the Iranian part of the ”northeastern margin” of the Tethyan Seaway were characterized by abundant biogenic components dominated by ...

Biometric study of late Oligocene larger benthic Foraminifera (Lepidocyclinidae and Nummulitidae) from the Qom Formation, Central Iran (Tajar-Kuh section)

Journal of Paleontology, 2020
. The Oligocene strata of the Qom Formation from the Tajar-Kuh section, Central Iran, are rich in various Larger Benthic Foraminifera (LBF). Morphometric studies of the internal features of the LBF tests were carried out based on matrix-free specimens ...

FACIES ANALYSIS AND STRATIGRAPHIC SEQUENCE ARCHITECTURE IN A BACK-ARC BASIN IN CENTRAL IRAN: A CASE STUDY FROM THE EARLY MIOCENE OF THE QOM FORMATION

Periódico Tchê Química, 2020
Marine deposits of the Qom Formation, which is an important gas reservoir in Central Iran with the age of Early Oligocene to Early Miocene, is studied to determine facies, sedimentary paleoenvironment, and depositional sequences.

Miogypsinid biostratigraphy in lower Miocene Qom Formation, Central Iran

Micropaleontology, 2019
The 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,
