Petrogenesis and Sr-Nd isotope data of the Chadegan metabasites, Sanandaj-Sirjan Zone, Iran

Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2016
The metabasites of Chadegan belong to the Sanandaj-Sirjan Zone and include eclogite, garnet amphibolite and amphibolite that have been affected by several tectono-metamorphic events.

Metamorphic conditions of dolomitic marbles from the Qori metamorphic complex, southern Sanandaj-Sirjan zone, using phase thermodynamic diagrams [PDF]

علوم زمین خوارزمی
The Barrovian-Qori metamorphic complex, which is exposed in the southern part of the Sanandaj-Sirjan zone, has a succession of metaultramafic, metabasite, metapelite, metacalcic silicate, and marble lithological diversity.

Ecological and Statistical Evaluation of Genetic Algorithm (GARP), Maximum Entropy Method, and Logistic Regression in Predicting Spatial Distribution of <i>Astragalus</i> sp. [PDF]

Scientifica (Cairo)
This study aims to evaluate the potential habitat of Astragalus sp. using three different species distribution modeling methods: the maximum entropy (MaxEnt) model, the Genetic Algorithm for Rule‐Set Production (GARP), and logistic regression. The primary objective was to identify key environmental factors that influence the spatial distribution of ...

Bashkirian foraminifera in the Sanandaj-Sirjan Zone (Iran): Their importance in taxonomy, biostratigraphy, and palaeobiogeographic reconstruction of the southern margin of Western Palaeotethys

Journal of Asian Earth Sciences, 2023
A noteworthy Lower Pennsylvanian fusulinid fauna is, for the first time, reported from the Sanandaj-Sirjan Zone in Iran. From the main outcrop, eighty five species of thirty genera belonging to two classes, five orders, five suborders, seven superfamilies, sixteen families, and seven subfamilies are examined.

A New Lithospheric Density and Magnetic Susceptibility Model of Iran, Starting From High‐Resolution Seismic Tomography

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 12, December 2023., 2023
Abstract We propose a new model for the crust and upper mantle in Iran by joint inversion of gravity and magnetic fields, constrained with a seismic tomography model. We then calculate shear modulus from the Vs velocities and densities. The crust and mantle tomography model is first converted to a density cube through empirical and petrological ...

Tectono‐Sedimentary Evolution of Shale‐Related Minibasins in the Karvandar Basin (South Sistan, SE Iran): Insights From Magnetostratigraphy, Isotopic Dating, and Sandstone Petrology

Tectonics, Volume 42, Issue 11, November 2023., 2023
Abstract Sediments deposited into foreland basins can provide valuable insights related to the geological evolution of their hinterlands. Located in the peripheral foreland of the South Sistan Suture Zone (SE Iran), the Karvandar Basin exhibits a several‐kilometer‐thick shallow‐marine to continental clastic sedimentary sequence forming elongated sub ...

Tectonics, Base‐Level Fluctuations, and Climate Impact on the Eocene to Present‐Day Erosional Pattern of the Arabia‐Eurasia Collision Zone (NNW Iranian Plateau and West Alborz Mountains)

Tectonics, Volume 42, Issue 8, August 2023., 2023
Abstract The NNW Iranian Plateau and west Alborz within the Arabia‐Eurasia collision zone are characterized by three main tectono‐stratigraphic zones, crosscut by the Qezel‐Owzan River (QOR) Basin. The interplay between present‐day deformation and climate, which control the landscape evolution of the region, is still poorly constrained.

Paleomagnetism From Central Iran Reveals Arabia‐Eurasia Collision Onset at the Eocene/Oligocene Boundary

Geophysical Research Letters, Volume 50, Issue 12, 28 June 2023., 2023
Abstract We present two robust and well‐dated paleomagnetic poles from upper Eocene and Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These two poles place Iran ∼3.7°–3° of latitude south of its present position between ca. 40 and 23 Ma.

Shattered Veins Elucidate Brittle Creep Processes in the Deep Slow Slip and Tremor Region

Tectonics, Volume 42, Issue 4, April 2023., 2023
Abstract Deep Slow Slip and Tremors (SSTs) are a combination of transient clusters of tectonic tremors and slow slip associated with extremely elevated fluid pressures. SSTs are thought to reflect a transition from viscous to brittle plate interface rheology and likely exert a first‐order control on megathrust seismicity.
