We analyse magnetotelluric data recorded in the Garhwal Himalaya corridor, India, to study dimensionality and strike direction of the geoelectric structure. The geoelectric structure dimensionality in the corridor shows spatial variation with period. Geoelectric strike directions of the main Himalayan thrusts associated with the main arc - Main Frontal Thrust, Main Boundary Thrust and Main Central Thrust - are N72°W ± 8°, N70°W ± 3° and N71°W ± 6° respectively. Cross-strike directions oriented transverse and oblique with respect to the main arc geometry are also delineated. Transverse feature is constrained using 3D modelling.

Abstract


We analyse magnetotelluric data recorded in the Garhwal Himalaya corridor, India, to study dimensionality and strike direction of the geoelectric structure. The geoelectric structure dimensionality in the corridor shows spatial variation with period. Geoelectric strike directions of the main Himalayan thrusts associated with the main arc - Main Frontal Thrust, Main Boundary Thrust and Main Central Thrust - are N72°W ± 8°, N70°W ± 3° and N71°W ± 6° respectively. Cross-strike directions oriented transverse and oblique with respect to the main arc geometry are also delineated. Transverse feature is constrained using 3D modelling.
