Abstract :

Structural Fracture Map of Taknar Zone in Central Iran has been drawn using 6 applied remote sensing methods. In this paper detected fractures were classified to 6 main directions. Then rose
diagrams of the fractures were drawn for 5 different regions of the zone. Most of the fractures and variety of them were concentrated in the central and southern part. In the next part of the study, Length values (L) of the fractures were calculated and classified in 3 main classes. It was found that the number of each fracture set decreased exponentially by increasing the length values. Calculating Spacing (S) values of each set and comparing them with the number of fractures showed similar conclusions: the number of each set decreased exponentially by increasing the spacing values. The other two calculated factors were Intensity (I) and Density (ρ). Most of the frequencies of the both factors were concentrated in the central and southern part. The next important calculated factor was “Fractal Dimension” (D). For the whole zone “D” was linear, which demonstrates the self-similarity of the fractures in different scales. In addition, it was found that the most values of “D” were related to the central and southern fractures. Based on above, reliability of remote sensing techniques for detecting faults has been demonstrated. It also seems that Doruneh Fault has had the main effect in the recent structural deformation and fracture development of Taknar Zone.
