This is a table that shows the elemental chemical composition of the Earth's crust. Keep in mind, these numbers are estimates. They will vary depending on the way they were calculated and the source. 98.4% of the Earth's crust consists of oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.

Scientists are continuing to refine the chemical and mineral composition of the Earth's interior by laboratory experiments, by using pressures 2 million times the pressure of the atmosphere at the surface and temperatures as high as 20000C.
A composition-based grouping highlights some common mineral associations that allow geologists to make educated guesses about which minerals are present in a rock, even with only a quick glance. By far, the most common minerals are the silicates, which make up 90% of Earth's crust.
As the composition of the Earth's crust is dominated by silicon and oxygen, silicate elements are by far the most important class of minerals in terms of rock formation and diversity. However, non-silicate minerals are of great …

Fifth, we know the composition of the Earth's crust and its mantle, by examining samples of them. For the lower mantle, we use experiments of the effect of pressure on upper (shallow) mantle minerals to predict the mineralogy of …
A mineral is a naturally occuring, homogeneous, ... The typical chemical composition of diatomaceous earth is 86% silicon, 5% sodium, 3% magnesium and 2% iron.
You can use a mineral's properties to determine its identity because the properties are determined by the chemical composition and crystal structure, or the way that the atoms are arranged. Figure 3.12: You can use the properties of a mineral to identify it.
The first process, WEATHERING, produces the materials that a sedimentary rock is composed of by mechanical (freezing, thawing) and chemical (dissolution of minerals, formation of new minerals [clays]) interaction between atmosphere, hydrosphere and earth surface rocks.
This is an estimation of the chemical composition of the crust based on our understanding of the relative proportions of different rock types in the crust and their average composition. Our understanding is limited for sure because the average continental crust is more than 40 km thick but we have no way to sample it directly.
