In this research the Mosha-Lavasan region (southeast Central Alborz) which covers Northwest part of east Tehran geological 1:100,000 map area were investigated. With structural studies were determined four classes based on their direction and according to the tectonical`s venture of Central Alborz region, their productive tensions was coincided on the study area. The four classes are: 1- reverse faults and folds with the trending E-W, 2- right lateral strike slip faults that have been associated with ESE-WSW folds, 3- Thrust and folds with SE-NW direction and 4- normal faults with N-S to NE-SW trending. We combine satellite photos, seismic data, result of morphotectonic studies and field observation for representation a model that showed sinistral movements of Mosha, North Tehran and Ushan faults caused of the area between their rounded clockwise. This rotation is clearly recognized in direction of folds.
