Abstract
Nezamabad fault zone with sinistral strike-slip (Dominant Mechanism) and NE-NW striking has located in the southwest of Iran, it is considered as one of the most important structures in the Zagros fold-thrust belt. This fault has caused complex structural deformations in the region. Also, there is an evidence for fault movement in the Khaftar anticline. This study aimed to fractal analysis, the impact of the Nezamabad fault on the lineaments extracted from the satellite image of Khaftar anticline. The box-counting method is an appropriate method for analyzing the fracture pattern for this study. Using this method, fractal dimensions were calculated for different parts of the Khaftar anticline. The difference between the fractal dimensions obtained from the lineaments associated with the Nezamabad fault well identifies how this fault is affected and the areas with different structural maturity in different parts of the Khaftar anticline. So that part A and C and their southern limbs, which include the SLA and SLC parts, have more fractal dimensions than other parts of the anticline, and these areas, especially the southern limbs of parts A and C are more active than other parts. Also, the difference in fractal dimensions of the Khaftar anticline as a result of differences in density, severity, and direction of stress due to Nezamabad fault performance in the area was evaluated.
