Tectonic Evolution Model of Nayband Fault (Central Iran), Based on Geophysical Data

The Iranian plateau is part of the Alpine-Himalayan orogenic belt which is the result of continental convergence, therefore, develop knowledge of continental small scale depression and its connection to surrounding areas can effectively describe the tectonic pattern of Iran. Strike-slip faults can have different roles in collision zones not only include the lateral movements of the crust. According to key roles of these faults to make structures and control basins of the area, in this article we described tectonic structures in boundary of Lut and Tabas blocks in Central Iran Microcontinent by aeromagnetic data, geological map and digital elevation model (DEM). Analysis data show horsetail splays and negative flowers structures with injection of magma. Nayband fault in N-S direction is one of the important strike slip faults in this area which in northern and southern terminations have several branches in thrust mechanism and affected morphotectonic of the region. Cross section of aeromagnetic data show parallel fractures with thin skin in position of magmatism in east of Nayband fault.
