The study area in terms of geological division is located in Zagros foldthrust belt. In
the present study, the following quantitative and qualitative methods of
geomorphology and structural geology were used together. Aerial photos, satellite
images, geological and topographical maps were studied and interpreted. Several
morphometric indices including facet%, sinuosity of mountain front (Smf), V ratio and
ratio of valley floor width to valley height (Vf) were calculated. Isobase line map as
well as lineament map and three maps of isofracture anomaly, lineament density
anomaly and lineament intersection intensity anomaly were plotted. Based on the
above mentioned analyses and presence of special morphotectonic features such as:
linear valley, deflected streams, fault scarps, water springs, elongated alluvial fans and
drainage basins, tectonically the study area is too active. Due to the deformation of Nar
anticline (Z shaped), it may be attributed to the presence of a N-S basement or blind
fault. This fault can also make different anomalies in drainage patterns, stream
directions and lineaments.
