The Earth's upper mantle is composed of rocks that have higher concentrations of mafic minerals (containing iron and magnesium) and lower in concentrations of the felsic minerals (aluminum and silica) than the rocks of Earth's crust.
The concentrations of the above elements therefore mean that the Earth's mantle is composed of a series of minerals that are predominately calcium / iron / magnesium aluminum silicates.
Such as:
- Olivine - (Mg,Fe)2SiO4
- Pyroxene - X(Si,Al)2O6, where X represents either calcium, sodium, iron or magnesium
- Spinel - MgAl2O4
- Garnet - X3Y2(SiO4)3 where X and Y can be a mixture of aluminum, iron, calcium, manganese or magnesium.
In the upper mantle, these minerals form the rocks types Peridotite, Dunite (Olivine-rich Peridotite), and Eclogite.

How do you make a sentence with upper mantle?
The crust and upper mantle make up the earth.
Which element is not found in large quantities in Earths mantle?
Gold is not found in large quantities in Earth's mantle. While it is present in the Earth's crust and in small amounts in the mantle, it is not one of the major elements that make up the mantle's composition.
What is the earths mantles most common elements?
The Earth's mantle is primarily made up of silicate minerals containing elements such as oxygen, silicon, magnesium, and iron. These elements make up the majority of the mantle's composition.
What are the five layers that make up the earth's interior and exterior?
The five layers that make up the Earth's interior are the inner core, outer core, mantle, upper mantle, and crust. The Earth's exterior consists of the atmosphere, hydrosphere (oceans and water bodies), lithosphere (crust and upper mantle), and biosphere (all living organisms).
Name three elements that make up most of earths mantle?
The rocks in earths mantel are made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. Iron, calcium, sodium, aluminum, and potassium are also present. The elements occur in rocks as oxides.

Name the three elements that make up most of earth's mantle?
The three elements that make up most of Earth's mantle are oxygen, silicon, and magnesium.
Is the lower mantle of the earth more solid than the upper mantle?
I think the lower mantle of the earth is mostly solid because even though the heat is extremely high, the pressureis high enough to make it a solid.
What parts of the earth make the asthenosphere?
The middle and lower mantle makes up the asthenosphere.

What are the natural elements that make up the earth?
The natural elements that make up the Earth include iron, oxygen, silicon, magnesium, sulfur, nickel, calcium, and aluminum. These elements account for the majority of the Earth's composition, found in the crust, mantle, and core.
What element make up the most mantle?
silicon
What material is the lower mantle made of?
The lower mantle is primarily composed of silicate minerals such as ferropericlase and silicate perovskite. These minerals make up the majority of the Earth's interior and contribute to its solid yet flowing nature.
What is the two most abundant element in the mantle?
The two most abundant elements in Earth's mantle are oxygen and silicon. They primarily exist in the form of minerals such as silicates, which make up the majority of the mantle's composition.
