Neotectonic Analysis in the North Slope of Bozqoosh Mountains, by Using Geomorphological Methods

The aim of this study is analysis of drainage basins neotectonic in the north slope of Bozqoosh Mountains by geomorphological methods. To attain this aim، It used of field observation، areal photographs and five geomorphic indexes in 20 basins of the north slope of Bozqoosh Mountains. Indexes were calculated by topography maps (1:50000)، geological maps (1:100000) and areal photographs (1:20000). All of maps drew by Arc/GIS. The results show that 40 % of drainage basins in study region have high activity tectonic. This basins located in middle portion of Bozqoosh Mountains. 35% of basins have moderate values of tectonic activity. They located in eastern portion of study region. 25% of basins of Bozqoosh have shown the lowest values of tectonic activity. There are numerous of morphotectonic evidences such as fault scarps، alluvial fans، fault valley، water fall and etc. which are in the north slope of Bozgoosh Mountains with high activity tectonic.
