A preliminary study and interpretation of LANDSAT-I imagery, covering a large area of Kumaun-Garhwal Himalaya. lying between 79° - 80°30' East longitude and 29°0' - 30°30' North latitude, reveals the presence of four dominant directions of lineaments trending NS, NE-SW, NW/WN-SE/ESE and E-W. The lineament fabric of the region represents axial directions of major folds, regional strike trends of thrusts and of transverse or strike-slip faults. The study is supplemented by detailed structural analysis of mesoscopic folds, planar and linear features present in rocks of three sections of the Kumaun Himalaya and it is suggested that the deformation in rocks of the region was the result of both compressional, tensional, and vertical uplift.

Abstract


A preliminary study and interpretation of LANDSAT-I imagery, covering a large area of Kumaun-Garhwal Himalaya. lying between 79° - 80°30' East longitude and 29°0' - 30°30' North latitude, reveals the presence of four dominant directions of lineaments trending NS, NE-SW, NW/WN-SE/ESE and E-W. The lineament fabric of the region represents axial directions of major folds, regional strike trends of thrusts and of transverse or strike-slip faults. The study is supplemented by detailed structural analysis of mesoscopic folds, planar and linear features present in rocks of three sections of the Kumaun Himalaya and it is suggested that the deformation in rocks of the region was the result of both compressional, tensional, and vertical uplift.
