Geometry and Kinematic Analysis of Young Normal Faults in Southeast Tabriz

M. Mohajjel; A. Cholgoly

Volume 19, Issue 74 , February 2010, , Pages 77-84


  Abundant normal faults were locally developed in Pliocene-Quaternary detritus and pyroclastic sediments of Sahand volcano in southeast Tabriz. Well exposed normal faults are synthetic and antithetic, horst and graben and half graben structure systems, drag folds and roll-over anticlines were produced ...  Read More

Bidhand Strike-Slip Fault System (South Qom)

R. Nadri; M. mohajjel; A. Bahroudi

Volume 19, Issue 74 , February 2010, , Pages 177-184


  The NNW-SSE striking Bidhand strike-slip fault system cut and displaced the Cenozoic volcanic and sedimentary rocks of the Urumieh-Dokhtar magmatic arc in south Qom. Structural evidences show that at least 16 km horizontal displacement in the Eocene volcanics has been caused due to dextral strike-slip ...  Read More

Separation of Paleostresses Phases Based on Heterogeneous Fault-Slip Data in the Central Part of Dehshir Fault

M. R. Moshrefi far; A. Alavi; M. Mohajjel

Volume 18, Issue 69 , February 2008, , Pages 64-73


           In this research, separation of paleostress phases in the central part of Dehshir fault is investigated based on the study of heterogeneous fault-slip data and their related slickenside lineations. These data are measured from the Certaceous (Taft limestone), ...  Read More

Gold Mineralization in Ductile – Brittle and Brittle Shear Zones, Zartorosht Deposits, Sanandaj-Sirjan Zone, Southwest of Sabzevaran

Gh. R. Rastgoo Moghaddam; E. Rastad; N. Rashid Nejad Omran; M. Mohajel

Volume 17, Issue 68 , February 2008, , Pages 108-129


         Zartorosht gold deposit is located in southeastern part of the Sanandaj-Sirjan zone. Rock units exposed in the area include mafic to intermediate volcanic series, metamorphosed volcano-sedimentary rocks and meta-basites intruded by basic to felsic dikes. These late ...  Read More

Microstructural Evolution of the Mantle Lithosphere in the Khoy Ophiolites - NW of Iran

M. Rahgoshay; I. Monsef; H. Shafaii Moghadam; M. Mohajjel

Volume 16, Issue 63 , March 2007, , Pages 2-17


  Petrofabric, structural and geochemical study of the ultramafic tectonites in the Khoy ophiolitic complex suggest that these tectonites including low-temperature NW-SE shear zones cut the high-temperature to medium-temperature NE-SW mantle flow direction. Microstructures in these tectonites, record a ...  Read More

Folding Style in Metamorphic Rocks of Faryab Area(South-East of Sanandaj-Sirjan Zone)

SH. Shafiei Bafti; S.A. Alavi; M. Mohajjel

Volume 16, Issue 64 , March 2007, , Pages 54-73


       Faryab area at the southeastern part of the Sanandaj-Sirjan zone, containing the Paleozoic rocks in the internal part of Zagros Orogen, displays two folding episodes through a progressive deformation event. Axial planes of recumbent F1 folds dip moderately to the north and the ...  Read More
