Abstract

Abstract
Study of geometric style of folding and their deformation analysis is one of the most important Geological topics of Zagros orogenic belt. Khaviz anticline is located in Khuzestan province and in the Zagros folded-thrust belt in the hanging wall of mountain front fault (MFF). This anticline is one of the most important anticlines of the Zagros; its importance is due to the Maroon's permanent river that passes from the middle of the anticline and divided it into two halves. This anticline has been studied by using morphometric forms such as triangular facets, win glass valleys and index of sinuosity of mountain front, Morphotectonic. The purpose of this study, is check the status of anticline Khaviz in terms of tectonic activity especially present age activities; with the help of the results of this study the status of constructed buildings on this anticline and in its vicinity, especially storage dam of maroon in terms of geological hazards can be evaluated. This shapes and indicators were studied in two anticline limbs individually; According to the results of this study it was found that mentioned Morphotectonic indicators has a direct relationship with the amount of tectonic activity and accordingly can be said that Khaviz anticline is in active status in terms of relative tectonic activity and also its northeastern limb than southwestern limb, it shows of own more activity. This feature can be due to existence Mansourabad subsurface anticline in the south west of Khaviz anticline and with distance less than a kilometer from it that has been leading to formation of back thrust in northeastern limb of Khaviz anticline and create more tectonic activity in this limb
