Petrology of the Paleogene shoshonitic volcanism in north Sarab area, NW Iran: Geochemical, Ar-Ar dating and Sr-Nd-Pb isotopic constraints

open access: yesJournal of Asian Earth Sciences: X, 2022
This study reports the earliest presumably known collisional magmatism of the NW Iran–eastern Turkey–Caucasus region from the north of Sarab city in East Azarbaijan province, NW Iran.

A few remarks on the Triassic paleogeography and geodynamic link between the Dinarides an the Serbo-Macedonian unit [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2020
A recently recycled tectonic hypothesis in which the Serbo-Macedonian Unit rifted off during Ladinian from the Dinarides is tested. The Triassic rifting, according to this concept, led to the opening and the formation of a northwestern branch of ...

Petrological Evolution of the Upper Mantle Beneath the Southern Sanandaj-Sirjan Zone: Evidence from Kuhshah Peridotite Massif, Southeast Iran [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2014
The Kuhshah ultramafic complex is located in the south-east of Sanandaj-Sirjan metamorphic zone, near the probable remnants of Neotethys plate in Iran. It consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros.

Late Triassic ostracods from the Lycian Nappes, southwestern Turkey: implications on taxonomy and palaeobiogeographical distribution

open access: yesBSGF - Earth Sciences Bulletin, 2020
The first ostracods known from the Lycian Nappes in southwestern Turkey are here reported, adding to the scientific understanding of marine ostracods during the Cordevolian, early Carnian, Late Triassic.

GEOCHEMICAL EVALUATION OF THE LATE MAASTRICHTIAN SUBDUCTION-RELATED VOLCANISM IN THE SOUTHERN NEOTETHYS IN VAN AREA, AND A CORRELATION ACROSS THE TURKISH-IRANIAN BORDER

open access: yes, 2014
The Yuksekova melange to the NE of Van, close to the Turkish-Iranian border is part of the Berit-Elazig-Van ophiolitic belt. It structurally overlies the Bitlis-Puturge metamorphic complex and includes the remnants of the southern Neotethys.

Species Diversity of Radulopecten (Pectinoidea, Bivalvia) in the Jurassic Seas of the Northern Central Neotethys: Reconsidering the Paleontological Information

open access: yesGeosciences
Radulopecten Rollier, 1911 was a common bivalve genus in the Middle–Late Jurassic seas of the northern Central Neotethys. The present work offers measurements of the species diversity dynamics of this genus after reconsideration of the species names and ...

Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.

Looking Under the Orogenic Lid—Assessing the European Basement Beneath the Alpine Wedge by U‐Pb Zircon Geochronology

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.

New Findings of Foraminifers and Age Correction of Callovian (Middle Jurassic) Marine Deposits of the Western Caucasus

open access: yesJournal of Marine Science and Engineering
A comprehensive understanding of Callovian (Middle Jurassic, Mesozoic) sedimentation and paleogeography requires examination of marine deposits of this stage across multiple geological domains on Earth.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.
