Structural and morphotectonic zonation of the Eastern Kopeh-Dagh

L. Aghajari; S. A. Alavi; M. R. Ghassemi; M. A. Kavoosi

Volume 26, Issue 104 , September 2017, , Pages 125-134

https://doi.org/10.22071/gsj.2017.50180

Abstract
  Different geological, structural and morphological characteristics of the eastern Kopeh-Dagh Province in NE Iran resulted in identification of several morphotectonic domains separated by major basement faults. Based on various field surveys, seismic reflection data, satellite images and cross-sections ...  Read More

Extension Analysis in Shemshak Sedimentary Basin (Balladeh Valley, Central Alborz)

M Mirzaei Souzani; A Shahidi; R Ramezani; F Alizadeh Sevari

Volume 24, Issue 95 , June 2015, , Pages 39-48

https://doi.org/10.22071/gsj.2015.41783

Abstract
  In order to survey the extensional forces dominated in central Alborz since Late Triassic (Norian) to Middle Jurassic (Early-Bajocian), synsedimentary normal and strike-slip fault systems in Balladeh valley which contains significant distribution of Shemshak Group have been studied. Analysis of σ3 ...  Read More

Extensional Structures in a Transpressional Tectonic Regime: the Relationship with Hydrothermal Vein Deposits and Porphyry Copper Deposits in NE Shahr-e-Babak

L. Ebadi; S.A. Alavi; Sh. Shafiei

Volume 21, Issue 81 , December 2011, , Pages 101-114

https://doi.org/10.22071/gsj.2011.54372

Abstract
  Hydrothermal vein and porphyry copper deposits are notable within Eocene volcanic rocks of Shahr-e-Babak area. In this paper, the structural patterns within Shahr-e-Babak area as well as the relationship between structural elements and the emplacement of dikes and hydrothermal vein and porphyry copper ...  Read More

Tectonic Evolution of the Alborz in Mesozoic and Cenozoic

Alireza Shahidi; E. Barrier; M.-F. Brunet; A. Saidi

Volume 21, Issue 81 , December 2011, , Pages 201-216

https://doi.org/10.22071/gsj.2011.54384

Abstract
  In northern Iran the Eo-Cimmerian orogeny resulting from this collision is associated with a regional unconformity and a major change in sedimentation. From Norian to middle Bajocian (Shemshak group), 030° trending extension is indicated by syndepositional normal faults. We assign this extensional ...  Read More
