Microstructures in quartz and feldspars of the Bomdila Gneiss from western Arunachal Himalaya, Northeast India: Implications for the geotectonic evolution of the Bomdila mylonitic zone

► Microstructural studies show inverted thermal profile in Bomdila mylonitic zone. ► Geothermometry gives similar temperature to assumed deformation temperature. ► Inverted thermal profile is related to imbrication and post metamorphic shearing.
