Abstract

At the northeastern edge of Great Kavir and at the south of the Toroud fault , structures on the Eocene and Neogene age rocks  seem diapiric at first look because of their pillow shape and evaporitic origin. Our study reveals that a contractional event on the end of Miocene time ,has caused a transpressional deformation along the Toroud fault . This deformation transferred into the south and resulted in folding and faulting of Eocene and Neogene age rocks. As contraction continued , Neogen age ductile sedimentary rocks displaced into the core of the folds or fault zones . this event in turn caused to the inclination of the axes of folds and increasing folding and formation of new structures. Up to now, active folding and faulting together with diapirism are the main deformation styles in the region .
