Abstract The present paper discusses the geochemical affinities, origin and ages of Jurassic granitoids Sanandaj-Sirjan Zone (SaSZ) in eastern part Zagros Thrust Zone. A multidisciplinary, integrated approach was carried out using existing granitoid data (major, trace, rare earth element isotopes) knowledge regional geology (geodynamic metamorphic setting), coupled with geophysical (magnetic su...

the subduction of the northern part of the tethys is documented by arc magmatism from upper triassic to lower eocene crosscutting the sanandaj-sirjan zone and from upper eocene to plio-quaternary in the urumieh-dokhtar magmatic zone, situated north of the ssz. neyriz ophiolite is part of middle eatern neo-tethyan ocean of mesozoic that geographically is related to ophiolites of nw-se iran, alon...

Abstract Hormuz salt formation is considered the origin of evaporated deposits in Zagros and its ductile behavior has been known as reason for inhomogeneous deformation Zagros. However, our knowledge about this limited to domes on surface. In study, local earthquakes recorded by a temporary dense seismological network 17 stations, deployed southern margin Simply Folded Belt (SFB) southwestern I...

This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formati...

Quantified balanced and restored crustal cross-sections across the NW Zagros Mountains are presented in this work integrating geological and geophysical local and global datasets. The balanced crustal cross-section reproduces the surficial folding and thrusting of the thick cover succession, including the near top of the Sarvak Formation (∼ 90 Ma) that forms the top of the restored crustal cros...
