Ali Bandegani; Ali Yassaghi; Mohsen Eliassi

Volume 30, Issue 118 , January 2021, , Pages 215-224

http://dx.doi.org/10.22071/gsj.2020.200068.1697

Abstract
  In this paper, the structural evolution of Bamu fault zone located in the Zagros folded belt zone is presented as an example of northeast-trending fault zone in the Zagros, using the kinematic and dynamic analysis of accompanied structures. Based on structural and paleostress analyzes two phases of shortening ...  Read More

2. Geochemistry and fractal analysis of enclaves in the Dehe Bala granodioritic pluton in order to investigate magma hybridization processes

Z. Gharamohammadi; A. Kananian; M. Eliassi

Volume 26, Issue 103 , June 2017, , Pages 295-308

http://dx.doi.org/10.22071/gsj.2017.46604

Abstract
  The Dehe Bala pluton is exposed approximately 45 km south-west of Boein Zahra town, Qazvin province. This pluton includes several mafic microgranular enclaves (MMES) with ellipsoidal and rounded shapes and varying sizes (from a few centimeters up to 30 cm). The MMEs are composed of diorite, monzodiorite ...  Read More

S. Rajabi; M. Eliassi; A. Saidi; A. Shahidi

Volume 21, Issue 82 , December 2011, , Pages 181-186

http://dx.doi.org/10.22071/gsj.2011.54454

Abstract
  In this research, heterogeneous fault slip data are used as the main data for doing paleostress analysis in North-Tehran tectonic wedge, which is restricted between Mosha and North-Tehran faults. Using these data and paleostress methods, the studied area is divided into 15 smaller stable stress regions ...  Read More

4. Source and Tectonic Setting of Zarjebostan (NE of Qazvin) Paleogene Volcanic Rocks using REE and HFSE Elements

K. Kalantari; A. Kananian; A. Asiabanha; M. Eliassi

Volume 17, Issue 68 , February 2008, , Pages 140-149

http://dx.doi.org/10.22071/gsj.2009.57853

Abstract
      Paleogene basic to intermediate lava flows of Central Alborz, in the northeast of Qazvin city (Zarjebostan), include trachy-andesite, basaltic trachy-andesite and basaltic andesite. These volcanic rocks are high-K calc-alkaline rocks. Based on the high LILE/HFSE and LREE/HREE ratios ...  Read More

5. Determination of the Geometrical Configuration of Trajectory in Kan-Karaj Area(Central Alborz) using Multiple Inverse Method

M. Eliassi; S. Ahmadian

Volume 17, Issue 67 , February 2008, , Pages 140-149

http://dx.doi.org/10.22071/gsj.2009.57825

Abstract
  Analysis of paleostress history in Kan_Karaj Area is the main object of this research. Paleostress phases were determined and categorized by numerous mesoscale faults containing slickenside lineations .The results were controlled and supported by some other geological features such as orientation of ...  Read More
