North face of Mt. Everest from Rongbuk monastery, Tibet,

Two detachemnts with a top-down-to-the NE sense of shear are marked in the photo: 1) the upper one “Qomolangma detachment” is the upper brittle fault; 2) the lower Lhotse detachment id the lower ducitle shear zone. The upper part of Mt. Everest is made by Ordovicina limestone of the Tethyan Sedimentary Sequence separated by the QD form the lower North Col Formation. The unti below the LD is the made of high grade rocks and Miocene leucogranites of the Greater Himayan Sequence.
