Higher Himalaya in the Bhagirathi section (NW Himalaya, India): its structures, backthrusts and extrusion mechanism by both channel flow and critical taper mechanisms

Shallow-generated damage within non-planar strike-slip fault zones: role of sedimentary rocks in slip accommodation, SW Holy Cross Mountains, Poland

“…Such angular relation conforms with the field observations from other areas (e.g. Mukherjee and Koyi 2010;Mukherjee 2010Mukherjee , 2013a. It is significant that this type of Riedel shears may be linked to the P or Y deformation bands within a very narrow, up to few centimetre wide zones that covers the area in the close vicinity of the fault surface.…”

The lithospheric density structure below the western Himalayan syntaxis: tectonic implications

“…The exception to this simplification is also documented in terms of out-of-sequence thrusting (Pandey et al 2004;Mukherjee, this volume, in prep. ) and backthrusting (Mukherjee & Koyi 2010;Mukherjee 2013a). In western Himalaya, the tectonic regime can be broadly categorized into (i) the Himalayan collision zone, orthogonal to the plate convergence, (ii) the western syntaxis including Pamir, Nanga Parbat and the Kashmir -Hazara syntaxis and (iii) the Western Fold Belt (WFB) of the Kirthar and Sulaiman ranges until the Chaman Fault, which marks the boundary of the Indian plate towards the west (Fig.…”

Quaternary extensional and compressional tectonics revealed from Quaternary landforms along Kosi River valley, outer Kumaun Lesser Himalaya, Uttarakhand

“…In the Panjal Thrust zone, the mesoscopic scale of normal faults suggests NE-directed subhorizontal extension (Thakur et al 1995). Ductile normal shearing are reported from MCT (=Munsi-ari Thrust) and from the upper strand of the MCT (=Vai-krita Thrust) along Sutlej River section, near Karcham (Mukherjee and Koyi 2010), and from Sainj area where the lower strand of MCT passes in the Bhagirathi River section (Mukherjee 2013). In the Nepal Himalaya, Mugnier et al (1994) reported normal displacement along most of the length of the MBT; suggesting that the orientation of the major principal stress within the Himalayan Thrust wedge deviates significantly from the horizontal and when this deviation exceeds the dip of the vectors normal to backtilted thrusts, the normal component of displacement may act along these faults.…”

“…normal faults, are well distributed in the Himalaya (Joshi and Hayashi 2010). Secondly, out-ofsequence thrusting (Mukherjee et al 2012;Mukherjee 2015) and back thrusts (Mukherjee 2013) are also present in the Himalayan orogen. It is believed that two categories of normal faults are developed in the Himalaya, viz.…”
