...Rodolfo Carosi; Chiara Montomoli; Salvatore Iaccarino; Hans-Joachim Massonne; Daniela Rubatto; Antonio Langone; Lorenzo Gemignani; Dario Visonà Abstract We investigated a contractional shear zone located in central Nepal, known as Kalopani shear zone. This high-temperature shear zone triggered...

.... 2016 ). High-temperature, top-to-the-south/SW shear zones in the GHS, above the HHD and below the STDS, have been recognized recently: the Kalopani Shear Zone in central Nepal ( Carosi et al. 2016 ); and the Tiyar Shear Zone in western Nepal ( Iaccarino et al. 2017 a ). According to Carosi...

... and UGHS are separated by the Chomrong thrust (CT), while the UGHS and STDS are separated by the Annapurna detachment (AD) in the Kali Gandaki valley and the Deurali detachment (DD) in the Modi Khola valley. Internally, the UGHS is deformed by the Kalopani shear zone (KSZ) in the Kali Gandaki valley...

...) and the Kalopani shear zone (Vannay & Hodges 1996), have also been mapped within the metamorphic core in the Annapurna region. All of these faults clearly post-date peak metamorphism and melting, as shown by the inversion of earlier formed metamorphic isograds along the Main Central Thrust zone and the omission...

... Gandaki valley may be indicative of post-metamorphic thrusting (e.g. Kalopani shear zone, Vannay & Hodges 1996 ; Khumbu thrust, Searle 1999 ), strain localization and contribution of shear heating, or perhaps diachronous metamorphism and peak temperature that varies with structural position...

... and a lower thrust-sense boundary. The bounding shear zones of the extruding channel may have opposite shear sense; the sole shear zone is always a thrust, while the roof shear zone may display normal or thrust sense, depending on the relative velocity between the upper crust and the underlying extruding...

...Michael P. Searle Abstract The Annapurna Detachment (AD) is a low-angle (∼20°–30° dip), north-dipping normal fault and ductile high-strain shear zone in calc-mylonites, and forms part of the South Tibetan Detachment (STD) that runs along 1800 km length of the Himalaya. The AD separates kyanite...
