This belt displays an inverted metamorphism progressing from a garnet to a sillimanite-K-feldspar zone toward higher topographic and structural levels. Because previously hypothesized mechanisms are not sufficient to explain inverted metamorphism, we propose that ductile shear displacements along ubiquitous, closely spaced S-C shear planes may have caused metamorphic inversion across a 15-20-km-thick, southwest-vergent, Higher Himalayan shear zone.
