Analysis of deformation models based on sigmoidal vein arrays in the Bahlgerd shear zone

MohammadAmir Alimi

Volume 32, Issue 1 , March 2022, , Pages 89-102

https://doi.org/10.22071/gsj.2021.277344.1895

Abstract
  The Bahlgerd shear zone in the northern margin of Bagheran Mountain is separated Eocene flysch from the Cretaceous ophiolite sequence and Quaternary sediments by southern Birjand and Bahlgerd faults. In the deformation evaluation , sigmoidal array arrays located in sandstone units have been used as strain ...  Read More

Effect of Structural Controllers on Ore Mineral Deposits of Cheshmeh Khouri Area (Northwest of Birjand)

KH Kavyani Sadr; M.M Khatib; M.H Zarrinkoub

Volume 24, Issue 95 , June 2015, , Pages 323-342

https://doi.org/10.22071/gsj.2015.42086

Abstract
  Cheshmeh Khouri is an area which mainly comprises a zone of parallel, en-echelon faults along which metallic and non-metallic mineralization is observed. Structural controllers are important factors in the formation of the structural elements of the area such as dykes, faults, joints, folds, and particularly ...  Read More

Structure of Shear Zone and Folds Interference Patterns in North Esfajerd, Sanandaj- Sirjan Zone

E Moosavi; M Mohajjel

Volume 23, Issue 91 , June 2014, , Pages 119-130

https://doi.org/10.22071/gsj.2014.43800

Abstract
  The North Esfajerd ductile shear zone is exposed in NE Golpaygan in the Sanandaj-Sirjan zone. The shear sense indicators are observed in the both outcrop and microscopic scales in this shear zone. These indicators are representing a NW striking dextral shear. The dynamic analysis and outcrop- scale indicators ...  Read More

Role of Detachment Surface in Local Thickening and Shear Folding,Shurab Syncline, Southeast Qom

Mohammad Mohajjel; Z. Rahami; F. Shabani

Volume 21, Issue 82 , December 2011, , Pages 11-16

https://doi.org/10.22071/gsj.2011.54434

Abstract
  Lower-red, Qom and Upper-red Formations with Pliocene conglomerates were all folded in Shurab syncline containing northwest-southeast axial trace in southeast Qom city. In the southeastern part of the northern limb of the Shurab syncline, gypsum and marl elastic units of the Qom Formation have played ...  Read More

Relative Strain Pattern in Ali Abad Damagh Granitoid

R. Samanizadegan; M. Mohajjel

Volume 21, Issue 81 , December 2011, , Pages 69-74

https://doi.org/10.22071/gsj.2011.54209

Abstract
  The Ali Abad Damag granitoid is intruded in Triassic-Jurassic schists located 35km south of Hamadan, southeast of the Alvand batholith. Northeast-southwest oriented mylonitised Ali Abad Damag granitoid has been intruded into a strike-slip dextral ductile shear zone. Abundant deformed enclaves exist in ...  Read More

The Geometric, Kinematics and Deformation Stage Analysis of Metamorphic Rocks around Mashhad

M. Koohpeyma; M.R. Sheykholeslami; M.R. Ghasemi

Volume 19, Issue 74 , February 2010, , Pages 99-106

https://doi.org/10.22071/gsj.2010.57339

Abstract
  The metamorphic rocks around Mashhad city were suffered by several stages of metamorphism and deformation. Special mineral and structural elements were formed in these stages. Metamorphic grade in the pellitic rocks changes from green schist to amphibole facies. Foliations generally are steep toward ...  Read More

Structural Analysis of Simin-Darreh Moradbeik Shear Zone,South of Hamedan

L. Izadi kian; A. Alavi; M. Mohajjel

Volume 19, Issue 75 , January 2010, , Pages 39-46

https://doi.org/10.22071/gsj.2010.55432

Abstract
  The Simin- Darreh Moradbeik shear zone is located in the south of Hamedan city with 5 km width and at least 10 km length. The portion of contact metamorphic rocks, plutonic rocks and migmatits are affected by this shear zone. At least three ductile deformation stages are recognized by folding and foliation ...  Read More

Study of Chemical and Structural Changes and Determination of Temperature in a Progressive Deformation: Evidences from Zarrin Shear Zone, Ardekan

F. Masoudi; M. Mohajjel; F. Shaker Ardekani

Volume 19, Issue 73 , January 2009, , Pages 11-16

https://doi.org/10.22071/gsj.2010.57195

Abstract
  The Zarrin area in the north of Ardekan is the part of Central Iran Zone. Some homogenous parts of Zarrin granite located in the shear zone changed to mylonites and ultramylonites. Microstructural evidence and deformation investigation show that chemical and structural changes occurred during the progressive ...  Read More

Geometrical and Kinematic Analysis of Western Half of Meyamey Fault
