Study on west Namco thrust Three ductile shear zones were discovered in Gayalong, Elongnubu and Shenjue-Gechangchayu, and geological features, deformation, motion direction and structural pattern are studied in detail for major thrust faults, ductile shear zones and folds in west bank of Namco Lake, leading to identification of west Namco thrust . And west Namco thrust and ophiolite mélanges outcropped from west Namco Lake to Yongzhuzangbu coexist together, indicating another tectonic suture in the Tibetan Plateau termed as the Namco-Yongzhu suture or NYS with its east extension to Jiali fault.
