Photomicrographs of metamorphic rocks near the shear zone in far-eastern Nepal Himalaya. a A strong mylonitic foliation of augen gneiss with asymmetric clast-tails of top-to-the-SSW sense in the Sisne Khola Augen Gneisses. b S-shaped inclusion train in garnet core in garnet schist of the Khare Phyllites. c S–C composite fabrics in garnet schist of the Khare Phyllites, showing a top-to-the-SSW sense of shear. d Elongated quartz of garnet–mica gneiss in the Junbesi Paragneisses. e. Asymmetric clast-tails and mica fish of sillimanite-bearing mylonitic gneiss near the HHT, showing a top-to-the-SW (thrust) sense of shear. f A boudin of sillimanite grain of sillimanite-bearing mylonitic gneiss near the HHT
