Role of inversion tectonics in structural development of the Himalaya

Analysis of surface and subsurface structures, variation of shortening amounts obtained by restoration of deformed cross-sections, and occurrence of younger hangingwall rocks over the older footwall rocks across the Vaikrita Thrust in the Higher Himalaya suggests reactivation of early normal faults as thrusts. Based on this, an inversion tectonics model is proposed for structural development of the Himalaya. The model explains the geometrical shape of the Himalaya as primary arcuation and helps in resolving superimposed deformation in the region.
