What kind of soil does Mount Everest have?

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.
The lower section of Mount Everest is known as the ‘Rongbuk Formation’ and makes up the first 7,000 meters. This region of Everest is formed from sillminite-K-feldspar grade schist and a banded metamorphic rock called gneiss, which has a similar composition to granite. Also a number of dikes of leucogranite and sills, which are horizontal sheets of igneous rock stuck between older rock beds.
The middle part of Mount Everest is known as the North Col Formation, 7,000 to 8,600 meters. This section, itself, can be divided into different parts, the top 400 meters, named the ‘Yellow Band’, is formed from linked beds of a brown, Middle Cambrian, marble (diopside-epidote-bearing), muscovite-biotite phyllite (which contain silicate minerals) and semischist (a partly metamorphosed, layered sedimentary rock).
The Qomolangma Formation, otherwise known as the ‘Jolmo Lungama Formation’, consists of layers of Ordovician limestone and recrystallized dolomite, along with siltstone and laminae, together forming colours ranging from white to dark gray. Starting at 8,600 meters above sea level (above Yellow Band), the Qomolangma Formation ends at the summit.
