Decapod crustaceans from the lower Miocene Qom Formation of the Isfahan area, Central Iran

Boletín de la Sociedad Geológica Mexicana, 2021
From the lower Miocene (Burdigalian) of the Qom Formation, exposed in three sections (Kuh-e-Donbeh, Bagher-Abad, and Vartun) in Central Iran, a deca-pod crustacean assemblage is described. The specimens exhibit two modes of preservation: carapaces (either isolated or with attached appendages) and isolated cheliped elements.

Microfacies models and sequence stratigraphic architecture of the Oligocene–Miocene Qom Formation, south of Qom City, Iran

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.

Evaluation of Erodibility of Formations in the Khangah-Sorkh Watershed (Urmia) Using a Rain Simulator [PDF]

پژوهش‌های آبخیزداری, 2020
Erosion is one of the major causes of waste of water and soil. Perhaps the main reason for failure to control erosion is the weakness of knowledge and recognition of this phenomenon. Due to the great value of soil and the subsequent problems arising from
