Abstract

 
Abstract: The Saqqez area, situated in NW of Sanandaj-Sirjan metamorphic zone, was affected by several deformation stages which exhibit as forming of different faulting stages in Ductile to Brittle environments. The development of faults plays an import role in establishment of structural framework and deformation of this area. In this research, the outcropped rock units and main lineaments were extracted by using of remote sensing and GIS techniques. Then, the main and minor faults were defined and measured (their characteristics) in field surveys. The results of Kinematic and Geometrical analysis show that three stages of faulting were happened. The arrangement of faulting primacy is: the first stage faulting (with N130-140 trend) has deformations in ductile circumstance (in western part). Then, this stage was cut by second order of faulting (N60-70) in ductile to ductile-brittle condition. Finally, all of faulting were ruptured and offset by third order faults with N10-20 trend in brittle condition. These three stages of faulting formed the curve-shape of structures and rock unit patterns.
