The study zone is a part of 1:100000 Anarak map which is located in the east of Isfahan province, at 10 km North of Anarak town. The Structures of this Zone is formed in Anarak-Khor region and are affected by the movement toward the north of Arabian plate, and activation of two strike-slip faults (Dorouneh and Biabanak) as a result of the mentioned movement. There is thrust fault in Chahshoureh with the east-west direction. This fault is not only a thrust but also it has during the different duration, dextral component, and then instal components. Polymetal mineralization is restricted to the hanging wall and into vein and veinlet of the listwanites of the study zone. Litswanites are uncommon carbonated rocks that forms from the alteration of ultramafic units and are abundant in silicic-carbonated threads. Ophiolites of this area belong to the ring ophiolites of central Iran. In this study, the direction of an effective paleo-stress field is reconstructed with the collecting data from slickenlines of faults and processing them by using inversion method. Trend and position of principle paleo stress axes are calculated from analysis of slickenlines by using T-tecto3 software, and it is found a that listwanites has formed in a tear fault. As the tectonic regime of the study zone show an iterative model it could be listwanites are forming is the similar way and restricting U- mineralization to their veins and veinlets. Also, according to the same forming, it could be concluded that in the west listwanites we have a poly-metal and U-mineralization.
