Figure 6
CCP stacking of PRFs using 1-D IASP91 velocity model along three profiles, whose locations are shown in Fig. 1a. Dotted lines show north dipping Main Himalayan Thrust (MHT), Moho and Lithosphere-Asthenosphere Boundary (LAB) below the Lesser Himalaya in the Uttarakhand Himalaya (a) AA’ profile, (b) BB’ profile and (c) CC’ profile. The locations of these profiles are shown in Fig. 1a. Black dotted elliptical areas mark the locations of mapped three lithospheric structures (C1, C2, and C3), which are spatially correlating with the northward extension of the DHR, inferred tectonic boundary and GBF. Thick pink, white and black dotted lines mark the north dipping MHT, Moho and lithosphere. While inverted triangle shape areas (marked by very thick black dotted lines) represent the highly deformed and segmented crustal and lithospheric areas (ER1 and ER2) within the northward extension of the inferred tectonic boundary and GBF, respectively, which are transverse to the Himalayan collisional boundary.
