Deformation flow analysis and symmetry of Goushti shear zone, Sanandaj-Sirjan metamorphic belt, Iran
Finite strain and vorticity analyses were carried out in the deformed conglomerate and micro-conglomerate of Goushti shear zone in the Sanandaj-Sirjan metamorphic belt (Zagros Mountains Iran). These deformed rocks are bounded between two NE and SW major thrust faults. Finite strain measurements on three principal planes of strain ellipsoid show the higher amounts of strain ratios near the major...

The Khushab anticline is located in the Zagros fold-thrust belt in the Lurestan. This anticline is affected by the Balarud fault zone, which is a part of Mountain Front Fault between the Lurestan and Dezful Embayment zones. Based on the measurement of the elements of fold style, this anticline is analyzed. According to these measurements, this anticline is a noncylindrical, asymmetrical and dis...
This research deals with the geometry of Khalakan Anticline by using field data. The anticline is located in NE Iraq, within High Folded Zone Iraqi Western Zagros Fold – Thrust Belt where southwestern limb it represents boundary between Low and folded zones. age exposed rocks study area ranges from Cretaceous to Late Pliocene. Qamchuqa Kometan formations expose two limbs as oldest rocks, while ...
Abstract We present two robust and well‐dated paleomagnetic poles from upper Eocene Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These place Iran ∼3.7°–3° of latitude south its position between ca. 40 23 Ma. Our new declination data indicate that block may have experienced a ∼11.6° clockwise rotation since Late Eocene. integrated our with retrodeformed margins Zagros c...
Metadon persicus Gilasian & Reemer sp. nov. is described, based on a single female specimen from the Zagros mountains in Iran. Morphological variation among the members of the genus Metadon Reemer and their distribution in the world are discussed. Photographs of the new species are provided. The subfamily Microdontinae represents a new taxon for southwestern Asia and the genus Metadon is report...
The Kashkan Formation (Paleocene to Middle Eocene), consists of conglomerate, sandstone, and siltstone in the Zagros Folded zone, southwest Iran. Type of the sedimentary facies, architectural elements and trace fossils show that Kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. The formation displays coarsening-upward succession reflects ...
