Exhumation of the Tutak gneiss dome occurred in a transpressional regime between the Arabian plate and the Central Iranian microcontinent. The Tutak gneiss dome is located in the eastern part of the basement-involved Zagros hinterland fold-and-thrust belt. This dome consists of exhumed middle crust including the Tutak and Sourian metamorphic comple...

Identifying landslide-prone areas is an essential step in assessing landslide risk and reducing landslide damage. In this paper, GIS-based spatial analysis has been used to prepare the landslide susceptibility (LS) map in the north of Lorestan province in western Iran. For this purpose, three main criteria and their sub-criteria were identified as...

New structural data on radiolarite and quartz mylonite rocks from the well-exposed Kamandan area are presented with the aim to shed light on the quantitative finite strain and vorticity analyses and strain partitioning along the Zagros transpression zone. Duplex structures, imbricate fans, thrust sheets and shear zones are well developed in the Kam...

Quantitative microstructural investigations involving finite strain and vorticity analyses of quartz-rich mylonites provide significant information regarding the kinematic characteristics of the Samen shear zone (SSZ) within the Sanandaj–Sirjan Metamorphic Belt, Zagros Mountain of Iran. A dominant top-to-the-SE sense shear in the study area is reco...

The basal decollement Darizhan shear zone in the hinterland of the Zagros orogenic belt exposes the amphibolite-mylonite in NW Iran. In this study, I discuss the deformation partitioning in terms of oblique convergence between the Afro-Arabian continent and the Iranian microcontinent. Rf/\(\phi \)-based finite strain analysis, Rxz varies ranging fr...

The Zagros hinterland fold-and-thrust belt is located in the central portion of the Zagros Thrust System and consists of the exhumed basement windows associated with NW-striking and NE-dipping flexural duplex structures that contain in-sequence thrusting and related folds. Mylonitic nappes of the basement were exhumed along deep-seated sole thrusts...

Zangul and Posht-e-Jangal anticlines are located at the WNW of Khorram Abad city, in Lorestan zone of Zagros fold- thrust belt (ZF-TB). Generally, folds in the ZF-TB are governed by thrust faulting. Therefore, the structural geometry of the folds, influence on the potential of reservoir structures, is controlled by thrust faulting which are almost...
