FRICTIONAL FUSION ON THE GLIDING PLANES OF TWO LARGE LANDSLIDES

FUSION PAR FRICTION SUR LES SURFACES DE GLISSEMENT DE DEUX GRANDS EBOULEMENTS

Frictional fusion is ascertained on the gliding planes of a deeply eroded landslide in the langtang Himal, Nepal and of the very well-preserved landslide of Kofels, Otztal, Australia. Both occur in gneissose rocks and exhibit large, low angle (18-30 deg) gliding planes between coherently displaced masses. The exposed gliding planes of the Langtang landslide are covered by a continuous sheet of rock glass ("hyalomylonite", Scott & Drever, 1953). In Kofels the gliding planes are accessible only at the top of the slide. The occurrence of pumice-like glass in this locality is derived from frictional rock malt squeezed into fractures or blown over the surface behind the displaced masses.
