Geological and fluid inclusion studies in the Muteh gold district, Sanandaj-Sirjan zone, Isfahan Province, Iran

, 1996
Metamorphic rocks of the Sanandaj-Sirjan zone host the Muteh gold mining district. The gold occurrences are in northwest-striking and northeast-dipping normal faults crosscutting the regional ductile pattern of the host rocks.

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 ...

Saheb Granitoid Batholith, North of Kurdistan: An Evidence of Cretaceous- Paleocene Magmatism in the Sanandaj-Sirjan Zone

Journal of Economic Geology, 2020
Introduction The Iranian plateau is part of the Alpine-Himalayan orogenic belt, which consists of several continental fragments separated from each other by major boundary faults and/or ophiolitic suture zones (Gansser, 1981).

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 ...

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.
