Upper Cretaceous Yüksekova Complex (Type Area), Easternmost Türkiye: Formation and Emplacement of a Proximal Back‐Arc Segment of a Tethyan Intra‐Oceanic Arc

Island Arc, Volume 35, Issue 1, January/December 2026.
ABSTRACT We provide the first comprehensive information and interpretation of the type area of the regionally important Upper Cretaceous oceanic arc, known as the Yüksekova Complex. Here, the arc's development is investigated using field observations, igneous and sedimentary petrography, micropaleontology of planktic foraminifera, x‐ray diffraction of ...

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt. During Neo‐Tethys subduction under Iran, there was pulsed arc magmatism with Middle Jurassic and Eocene magmatic flare‐ups ...

Unveiling Cenozoic Volcanism in the Takab‐Shahindezh Area Induced by Slab‐Mantle Interaction in the Zagros Orogen, NW Iran

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Zagros orogen records the closure of the Neotethys Ocean by northward subduction of the oceanic slab beneath the Iranian plate. Northwestern Iran has undergone episodic volcanism since the Eocene, due to a shift of tectonic regimes from subduction to collision and post‐collisional extension, although the dynamics responsible for such ...

Structural evolution of the Laibid pop-up structure, Sanandaj-Sirjan Zone, West Iran [PDF]

, 2011
The Laibid pop-up structure is located in the highly deformed sub-zone of the Sanandaj-Sirjan Zone, western Iran. In this zone, structural trends are parallel to the Zagros fold-thrust belt (NW-SE), but the pop-up structure has a different trend of E-W ...

Mississippian-Asselian (early carboniferous-early permian) foraminiferal faunas and biostratigraphy of the Shahreza-Abadeh regions (The Sanandaj-Sirjan Zone), Iran / Shirin Fassihi [PDF]

, 2017
The Mississippian‒Asselian (Early Carboniferous‒Early Permian) foraminiferal faunas and biostratigraphy were studied in three sections of the Shahreza‒Abadeh regions, in the Sanandaj-Sirjan Zone, in Iran.

Crustal Thickness Evolution Controls the Formation of Porphyry Cu Deposits in Collisional Orogens: An Example from Central Tethys

Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 522-531, April 2025.
Abstract The key factor that controls the genesis of porphyry Cu deposits (PCDs) in collisional orogens remains a debated topic. This study employs whole‐rock La/Yb proxies to quantitatively constrain the spatial and temporal variations in crustal thickness of the South Armenian–Iranian magmatic belt (SAIMB) within the Zagros orogen (central Tethys ...

Petrogenetic and tectonic aspects of collisional granitoids from the Sanandaj-Sirjan Belt of Iran [PDF]

, 2012
The Sanandaj-Sirjan granitoids (SSG) in western Iran are composed mainly of granite, granodiorite and tonalite. Chemically the rocks are peraluminous and metaluminous, and show S-and I-type characteristics.

A database of detrital zircon U–Pb ages and Hf isotopes for the Middle East (Iranian and Arabian plates)

Geoscience Data Journal, Volume 11, Issue 2, Page 107-117, April 2024.
A total of 41,342 detrital zircon U–Pb ages and 6,129 Hf isotopes were compiled. Different zircon features in response to the tectonic events in the Middle East. Potential uses in provenance and palaeogeographic analysis. Abstract The detrital zircon records significant information in the ‘source‐sink’ system.

Gondwanan eoarchean-neoproterozoic ancient crustal material in Iran and Turkey: Zircon U-Pb-Hf isotopic evidencespi1

, 2015
The Sanandaj-Sirjan Zone is a basement culmination northeast of the Neo-Tethys suture in Iran. In this zone near Azna, granite has a magmatic zircon U-Pb age of 568 ± 11 Ma, with 900-800, ca. 2400, and ca. 3600 Ma inherited cores. The ca.
