<p>The duplexes of Khunik are located at a distance of 18 kilometers in south of Qayen City with a trend of northeast to southwest. Khunik fault is a right-lateral strike-slip fault with a thrust component. Based on the geometry of the duplexas, region was built from two structures of horse tail. In duplexes of this area, are faults have strike-slip mechanism with thrust component. Based on determining of the paleo stress phase, and analysis of existing fractures and shortening trends caused by compression on duplexes of the region, was determined compression, mechanism and it was with maximum axis of N115 stress. The shortening rate was determined as 27.3percent and a total equivalent to 187 meters along the fault by using experimental modeling method in laboratory, which is corresponded with the calculation of the region parameters. According to field surveys and empirical modeling, region duplex has imbricate duplex model.</p>
