Stratigraphy, 2022
The Abderaz Formation was analyzed from four stratigraphic sections (Qaleh-Zo, Abderaz village, Mozduran pass (type section of the formation), and Chahchahe) in awest to east transect of the Kopeh-Dagh Basin. The Abderaz Formation is composed of light gray shale and marl alternated with limestone rich in echinoids and inoceramids.

Introducing some echinoderms from the Tirgan Formation, Kopeh-Dagh Basin, NE of Iran
2011A stratigraphic section from the Tirgan Formation was selected in Arkan village nearby Bojnourd city in order to study echinoderm fauna systematically. Many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper.

This paper shows how multifractal analysis can be used to characterize the spatial distribution of epicenters in the Zagros and Alborz-Kopeh Dagh regions of Iran. The main multifractal characteristics, Dq, f(αq), τq, αq and a set of multifractal parameters defined from the shape of the f(αq)-spectrum including the width of f(αq)-spectrum, nonuniformity

This study presents the nannostratigraphy and nannofossil events in the lower boundary of Kalat Formation in the East and West of the Kopeh- Dagh basin. The Kalat Formation comprises of coarse grained detritus limestone with subordinate sandstone intercalations. In the current study, six sections have been chosen in the East and West of the basin which

AbstractTwo sections from the Silurian deposits in the Central Iran Micro and Turan Plates were measured and sampled. These deposits are mostly composed of submarine volcanic rocks, skeletal and non‐skeletal limestone, shale and sandstone that were deposited in low to high energy conditions (from tidal flat to deep open marine).

Micropaleontology
The Abderaz Formation has been studied in five stratigraphical sections (Qarehso, Abderaz village, Muzduran pass (type section of the formation), Padeha village, and Shorab) in the east of the Kopeh-Dagh Basin. Twenty-four species of planktonic foraminifera belonging to eleven genera were identified. The vertical distribution of these species helped to

Benthic foraminiferal assemblages from Maastrichtian strata, Gansserina gansseri-Abathamphalus mayaroensis Planktonic Foraminiferal Zone, of the AbTalkh Formation at Aitamir section (west of the Kopeh-Dagh basin) were investigated in order to evaluate the palaeoenvironmental changes (organic matter flux and bottom-water oxygenation).
