The Eastern Khoy metamorphic complex of NW Iran: a Jurassic ophiolite or continuation of the Sanandaj–Sirjan Zone? [PDF]
Journal of the Geological Society, 2019 The Khoy complex in NW Iran has been widely regarded to consist of both Jurassic and Cretaceous ophiolites, but whereas the western Late Cretaceous ophiolite is unequivocal the nature of the eastern Jurassic body has been unclear. Field observations show that the presumed eastern meta-ophiolite has no similarities to an ophiolite sequence.

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 ...

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

Petrology and geochemistry of Noraldinabad rhyolites, NW Iran [PDF]
پترولوژی, 2023 Felsic igneous rocks record crustal evolutions and provide an important tool for determining the composition and modification of the crust (Zhang et al., 2018). Up to now, several classifications have been proposed for granites and rhyolites.

Contributions to Geophysics and Geodesy, 2020 A detailed knowledge of the thickness of crust and upper mantle structure is important for understanding a plate tectonics and geodynamics in the region. We use body wave for detecting details of the subsurface structure. The information in this research

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 ...

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 ...
