Symmetrical and closed Ezgeleh anticline is located in the fold and Thrust belt of Zagros zone and in the Lorestan subzone. The Trend of this fold is NW-SE. This fold like most of other Zagros folding is fold related fault and Detachment fold type. The oldest rock unit that outcrops in the core of the anticline is the Ilam unit, which consists of thin to thick layers of light gray to white limestone. In this research, the lateral growth of the Ezgeleh anticline due to the function of a hidden reverse fault has been investigated using morphotectonic indicators. Morphometry indicators such as BS،AF، SL، Hi, RE، C were used to examine transverse growth in this fold. Most of catchments are elongated and have parallel drainages in this fold. Investigation of tectonic morphological indices indicated transverse growth of this anticline and Its transverse growth mechanism is fixed hinges and rotating limbs. According to the evidence of fold growth the region is active and the seismic activities of the region confirm this.
