Multiple Detachment Folding in Pusht-e Kuh Arc, Zagros<subtitle>Role of Mechanical Stratigraphy</subtitle>

Modeling the flexural evolution of the Amiran and Mesopotamian foreland basins of NW Zagros (Iran-Iraq)

“…The most proximal part of the foreland basin is characterized by NW-SE Zagros trending anticlines buried beneath the large alluvial plains of Iraq and Iran [e.g., Dunnington, 1968;Mohammed, 2006]. The Zagros deformation front separates these Zagros folds from roughly N-S oriented large inverted folds that dominate the Persian Gulf and the Abadan plains [e.g., James and Wynd, 1965;Alavi, 2004;Abdollahie Fard et al, 2006;Vergés et al, 2011a].…”

“…Deformation in the Arabian cover of the Simply Folded Belt is mostly characterized by detachment folding and subsidiary thrusting [e.g., Sattarzadeh et al, 2000;Sherkati et al, 2005;Vergés et al, 2011a]. This deformation style is included in the geometric model, although folding of the cover has not been included in the Kinematic model.…”

Magnetostratigraphic Age Control of the Timing of Tectonic Deformation and the Shifting Depositional Environments in the Dezful Embayment, Iran

“…In foreland basins, growth strata mark stratigraphic intervals in deposition caused by tectonic deformation, which can therefore provide precise information about syntectonic sedimentation (Suppe et al., 1992). Such studies in the Zagros foreland basin are crucial for interpreting the evolution of fault‐related folds in space and time driven by the Arabia‐Eurasia collision (e.g., Ballato et al., 2017; Emami et al., 2010; Homke et al., 2004; Khadivi et al., 2010; Lashgari et al., 2020; Najafi et al., 2021; Ruh et al., 2014; Vergés et al., 2011, 2019). Magnetostratigraphy, together with biostratigraphy and/or radiometric dating, can provide an age control of both the growth strata and the marine/continental transition in the Zagros foreland basin.…”

Retracted: Control of Multiple Detachments on Structural Development in the Southern Junggar Fold‐and‐Thrust Belt, Northern Tian Shan: Implications for Seismic Hazard Assessment

“…The results of existing numerical and analog modeling and natural example observations demonstrate that spatial distribution (e.g., thickness) and rheological behaviors (frictional or viscous) of detachments have a crucial impact on structural development in contractional FTBs (Borderie et al., 2018; Briggs et al., 2006; Davis & Engelder, 1985; Gao et al., 2020; Massoli et al., 2006; Meng & Hodgetts, 2019; Ruh et al., 2012; Sherkati et al., 2005; Vergés et al., 2011). In the southern Junggar FTB, main detachments that contain mechanically weak layers (mudstone and coal beds) include the Lower Jurassic Badaowan Formation (J 1 b) (serving as a regional, deep detachment), and the shallower Lower Cretaceous and Paleogene detachments (Dong et al., 2007; Luo et al., 2007).…”

“…• Hutubi anticline is a pure sheardominated detachment fold, which has experienced multi-stage tectonic shortening since the Late Jurassic • Multiple detachments have predominantly controlled the structural segmentation in the southern Junggar fold-and-thrust belt • Lateral structural variations and kinematic evolution also need to be considered in seismic hazard assessment The results of existing numerical and analog modeling and natural example observations demonstrate that spatial distribution (e.g., thickness) and rheological behaviors (frictional or viscous) of detachments have a crucial impact on structural development in contractional FTBs (Borderie et al, 2018;Briggs et al, 2006;Davis & Engelder, 1985;Gao et al, 2020;Massoli et al, 2006;Meng & Hodgetts, 2019;Ruh et al, 2012;Sherkati et al, 2005;Vergés et al, 2011).
