What is the geology of mount Everest?

Answer 1

The three formations, or units, which make up the geology of Mount Everest are divided into sections. Geologists have named these, from the bottom to the summit respectively, the Rongbuk Formation, the North Col Formation and the Qomolangma Formation. These sections, or units, are divided by a low-angle fault, or a 'detachment', each one being forced over the next to form a, sort of, zigzag pattern.
