Abstract

The study area in this research is located in the Central Iran and south of Bayazeh village. Using remote sensing and field studies, the pattern of distribution and evolution of brittle and ductile structures in this part of Central Iran were studied. During remote sensing studies, using different filters, the fracture scattering pattern was investigated. In the field studies section, in order to control and study the faults and folds, structural measurements were performed from different parts of the study area. In the study of folded units, two folding with almost different geometric characteristics were identified that evolved under the influence of NW-SE and E-W convergence directions. Remote sensing and field measurement studies on faults showed three directions of NE-SW, NW-SE and N-S orientations for the main faults in the region. The paleostress field obtained from these studies identified several directions for maximum stress, which with the direction of northwest, northeast, south and east and low to horizontal plunge shows the compressional mechanism prevailing in the region. Hajiabad and Bayazeh faults as the main faults along with minor faults were compared with Riddle fracture pattern and despite the great impact on the spread of faults and folds in the region, it was found that they have not yet reached their structural maturity.
