40Ar–39Ar dating of volcanic rocks of the Shyok suture zone in north–west trans-Himalaya: Implications for the post-collision evolution of the Shyok suture zone

Long‐lasting intracontinental strike‐slip faulting: new evidence from the Karakorum shear zone in the Himalayas

“…This view, of recent and short‐lived ductile deformation, appears to have been widely accepted (Ravikant, 2006; Phillips and Searle, 2007; Rutter et al. , 2007; Bhutani et al. , 2009; Streule et al.…”

“…2a), deformation post-dates magmatism, starting after 15.7 Ma and lasting <2 Ma. This view, of recent and short-lived ductile deformation, appears to have been widely accepted (Ravikant, 2006;Phillips and Searle, 2007;Rutter et al, 2007;Bhutani et al, 2009;Streule et al, 2009;Wang et al, 2009) and has important bearings on the continental collision history and mechanics. Herein, we present data demonstrating that right-lateral deformation, which is still active today, started more than 18 Ma ago near Tangtse and suggesting that there are close spatial and temporal relationships between strike-slip shearing and magmatism.…”

Linkage of paraglacial processes from last glacial to recent inferred from Spituk sequence, Leh valley, Ladakh Himalaya

“…The Leh valley is bounded by Ladakh hill range (undeformed Ladakh batholith and Khardung volcanics, an igneous rock complex) to its north east and Zanskar hill Range (meta-sedimentaries: Paleozoic to Palaeocene ageZanskar Formation and latest Palaeocene to early Miocene -Indus Formation) to its southwest (Brookfield and Andrews-Speed, 1984;Garzanti and Van Haver, 1988;Searle et al 1990;Searle et al 1997;Sinclair and Jaffey, 2001;Jamieson et al 2004;Wu et al 2007;Bhutani et al 2009). The contact between Indus Formation and Zanskar Formation is manifested by Choksti thrust along the northeastern fringe of the Zanskar hill Range.…”

Zircon U–Pb geochronology, mineral and whole‐rock geochemistry of the Khardung volcanics, Ladakh Himalaya, India: Implications for Late Cretaceous to Palaeogene continental arc magmatism

“…The existing tectonic models suggest that there are two main suture zones that were formed due to two subduction events along the entire southern boundary of the Eurasian Plate, namely, (a) Early-Late Cretaceous-the Shyok Suture Zone (SSZ) represented by the Nubra ophiolitic sequence and (b) the Indus Suture Zone (ISZ) denoted by the Nidar ophiolitic sequence (Dubois-Côté et al, 2005;Dunlap & Wysoczanski, 2002;Jain, 2014;Rai, 1983;Reynolds, Brookfield, & McNutt, 1983;Robertson & Collins, 2002;Thakur, 1992;Thakur & Misra, 1984). The ISZ is regarded as the main suture between the Indian and Eurasian continental plates (Bhutani, Pande, & Venkatesan, 2009) sutured at ca. 50 Ma (Beck et al, 1995;Green, Searle, Corfield, & Corfield, 2008;Meng et al, 2012), and at ca.…”

“…BS: Bangong Suture; ISZ: Indus Suture Zone; MBT: Main Boundary Thrust; MCT: Main Central Thrust; SS: Shyok Suture Zone; STD: South Tibet Detachment; ZS: Zanskar Shear Zone. (b) Geological map of the western Ladakh Himalaya highlighting various formations of the Shyok suture zone wedged between the Ladakh batholith in the south and the Karakoram batholith in the north (after Upadhyay, Sinha, Chandra, &Rai, 1999 andBhutani et al, 2009). The present study area is shown in the rectangular box ( Figure 1b) [Colour figure can be viewed at wileyonlinelibrary.com] proposed the evolution of island arc tectonic setting for the Shyok volcanics, and the Khardung acid volcanics was also considered to be related to an island arc volcanism (Sharma & Gupta, 1983;Srimal et al, 1982).…”
