Crustal structure, restoration and evolution of the Greater Himalaya in Nepal-South Tibet: implications for channel flow and ductile extrusion of the middle crust

“…Although pure shear flattening did compress the sequence, new material was constantly being fed into the channel from crustal subduction beneath the active MCT during the late Oligocene and Miocene. Folding and thrusting in the Tethyan sedimentary rocks above the STD occurred earlier than shortening and thickening in the GHS beneath, although some breakback thrusting and north-directed backthrusting did occur late in the sequence (Searle 1986;Corfield & Searle 2000;Murphy & Yin 2003). The STD normal faults do not relate to wholescale crustal thinning, whole crustal extension or topographic collapse.…”

Crustal–lithospheric structure and continental extrusion of Tibet

“…Kongur, Muztagh Ata) are not offset across the fault (Robinson et al 2007;Robinson 2009a,b). The southeastern end of the Karakoram Fault merges into the Indus-Yarlung Tsangpo suture zone south of Mount Kailas, where north-directed backthrusting occurs along the northern margin of the Indian plate (Searle 1996;Searle et al 1997b) and north-south extensional faulting occurs in the Purang graben (Murphy et al 2000;Murphy & Yin 2003). The Karakoram Fault forms one major strand along the Nubra Valley but in the Tangtse region the fault splays into two branches, the main strand, the Tangtse Fault strand, to the SW and the Pangong Fault strand to the NE, both of which display spectacular mylonites (Fig.…”

Testing the effects of topography, geometry, and kinematics on modeled thermochronometer cooling ages in the eastern Bhutan Himalaya

“…This approach allows topography to respond to deformational loading and erosional unloading. For models using the static and responsive topographies, the initial topography assigned to the restored section simulates a preexisting foldthrust belt in the Tethyan sequence before the initiation of the MCT (Ratschbacher et al, 1994;Murphy and Yin, 2003;Webb et al, 2011). This topography maintains 0 km of elevation from the southern end of the restored cross section to the lower Lesser Himalaya.…”
