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 ...

Mineral chemistry of clinopyroxene: guidance on geo- thermobarometry and tectonomagmatic setting of Nabar volcanic rocks, South of Kashan

Journal of Economic Geology, 2017
Introduction The Nabar area that is a part of the Urumieh- Dokhtar volcano- plutonic belt is located in the south of Kashan. Research works such as Emami (Emami, 1993) and Abbasi (Abbasi, 2012) have been done about the geology of this area.

Garnet as a Proxy for Deciphering Polymetamorphic Histories: An Example From the Sanandaj‐Sirjan Zone of Iran

Geological Journal, Volume 60, Issue 4, Page 793-806, April 2025.
This work documents how the texture and composition of metamorphic garnet represent a valuable petrological archive capable of deciphering complex thermobaric histories. ABSTRACT In the central sector of the Sanandaj‐Sirjan zone of Iran, the Triassic‐to‐Jurassic ‘Hamedan Phyllites’ metamorphic complex shows a polymetamorphic evolution characterised by ...

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 ...

Geochemistry and petrology of volcanic rocks in the south of Natanz (The middle part of Urumieh-Dokhtar Magmatic Arc)

پترولوژی, 2020
The south Natanz volcanic zone located in the central part of Urumieh-Dokhtar magmatic arc and the north of Isfahan. The area is dominated by the Eocene volcanic rocks ranging from acidic to intermediate and relatively basic affinity. Petrologically, they consist of rhyolite, dacite, andesite, basaltic trachyandesite and basaltic andesite ...

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.

Geology and petrogenesis of the Sungun deposits: Implications for the genesis of porphyry-type mineralisation in the NW Urumieh–Dokhtar magmatic Arc, Iran

Ore Geology Reviews, 2021
Abstract The Miocene Sungun porphyry Cu–Mo systems, located in Azerbaijan belt, NW Iran, is associated with the high-Sr/Y magmas, which were engendered in a post-collisional setting. However, the petrogenesis of these fertile magmas and their mineralisation are still unknown.

Geochemical and geophysical investigations, and fluid inclusion studies in the exploration area of Zafarghand (Northeast Isfahan, Iran)

Journal of Economic Geology, 2017
Introduction Urumieh-Dokhtar Magmatic Arc (UDMA) is a good prospective area for Cu, Cu-Mo and Cu-Au deposits (Fig. 1A and B). The Zafarghand district is located in the central part of the UDMA and the northeastern Isfahan.

Magmatic-hydrothermal fluid evolution of the Dalli porphyry Cu-Au deposit; using Amphibole and Plagioclas mineral chemistry

Journal of Economic Geology, 2017
Introduction The formation of porphyry copper deposits is attributed to the shallow emplacement, and subsequent cooling of the hydrothermal system of porphyritic intrusive rocks (Titley and Bean, 1981).
