Abstarct: Nekarman – Tash area is located in eastern alborz Basin. Shahvar fault and Siah marz kuh is main fault of study area and some folds such as Nekarman and Dareh palang anticlain and Kuhe mishi syncline is main fold of study area. In this reasearch we investigate morphometric index such as (SL),(SMF),(Vf),(AF) with useness of global mapper , arc GIS and DEM. We use from this indexs to classify the tectonic activity of area. We determine 7 segment with topographic and drainage basins study in study area. At the final we use from mean index (index if lat tectonics relatives) and classify basins in 4 main group. Basins with tectonic activity of : 1- very high 2- high 3 – middle 4- low. With consideration of this ranking , investigations show all 5 basins of study area classify in group 2 with high tectonic activity. At the final investigations of this research show study area tectonically arrange area with high tectonic activity.
Shahvar fault system located in eastern alborz region. Paleozoic , Mezozoic and Cenozoic compose the stratigraphic lithology of study area. Structurs study area show of area have E-W until NE – SW trend.
The stratigaraphic succession in the study composed of Paleozoic, Mezozoic and Cenozoic Rocks.
