| Abstract:
in the present work, on the anticline of Gadvan (Gadaun) mountain that placed in northeast of shiraz, some investigation has done as preparation of lineaments map by Landsat 7 images, length, intersection, & counts density map of lineaments, calculate two geomorphic indices Smf & facet% and stereographic fold analysis which can use these items for structural analysis & morphotectonic investigation. Geomorphic indices show active tectonics in this area so that the rate of uplift is higher than the rate of mountain front erosion, estimated 1 to 5 mm/year. Also automatic and semi-automatic methods are used with manual method to enhance lineaments. Map of length, counts & intersection density show the area of fractures anomaly and also can help in position determination of ground water boreholes in Dariyan plane. Kind and attitude are determined by stereographic fold analysis too.
