Determination of the Geometrical Configuration of O1 Trajectory in Kan-Karaj Area (Central Alborz) using Multiple Inverse Method

Analysis of paleostress history in Kan - Karaj Area is the main object of this research. Paleostress phases were determined and categorized by numerous mesoscale faults containing slickenside lineations .The results were controlled and supported by some other geological features such as orientation of axial plane of folds, intrusion and stylolitic planes. The orientation of finite principal stress axes and geometrical shape of stress ellipsoid in a 4-D stress space were analyzed by determination of rotational axis of each sub-area, according to Anderson Theory. Two different stress phases were separated and geometrical configuration ofthe maximum compressional stress trajectory were illustrating on the structural map. The resulting trajectory shows north- south trend with an outstanding convergence to the north which reflects incremental intensity of stress in that direction during the fault system activities.
