Physical modeling of block rotation and the role of ductile sediments in the structural evolution of Kopeh Dagh and Zagros

Marzieh Rostami; Morteza Talebian; Abbas Bahroudi

Volume 31, Issue 3 , December 2021, , Pages 135-144


  Anticline axes in both orogenic belts of the Zagros and Kopeh Dagh are offset by NW-SE trending transvers faults. These faults are rotating anticlockwise due to their oblique orientation relative to maximum stress vector, causing shortening across the belt and elongation along the strike. The transverse ...  Read More

Assessment of Shear Strain Variation along Koch Fault Zone Based on Study of Foliation

F Porghiasian; E Gholami; M.M Khatib

Volume 24, Issue 1393 , March 2015, , Pages 63-68


  In this study, value of shear strain for the Koch fault zone was determined based on the angle of foliations with the edge of the Koch fault zone. The Koch fault zone with N-S trend is located in northeast of Birjand, at the end northwest of the Sistan structural zone. In the Koch fault zone shear strain(γ) ...  Read More

Structural Analysis of Mosha Fault in the Northeast of Tehran

S. Bahiraie; M. Abbasi; M. Almasian

Volume 16, Issue 64 , March 2007, , Pages 112-125


  Generally the most important factor in the structural evolution of Alborz is thrust and reverse faulting that often has an east-west trend, parallel to the mountain chain. Mosha fault, one of the main faults, in this study covers the area between longitudes 51˚, 30´ to 51˚, 45´ including ...  Read More
