Peridotite is an ultramafic rock (less than 45% silica) and mainly contains the minerals olivene (a magnesium iron silicate - (Mg,Fe)2SiO4) and pyroxene (XY(Si,Al)2O6 where x may be calcium, sodium, iron or magnesium) and so as can be seen from the chemistry of the two primary minerals contains significant amounts of magnesium and iron.
Peridotite is a type of ultramafic rock that is primarily composed of the minerals olivine and pyroxene. It is typically found in the mantle of the Earth and is associated with igneous processes such as the formation of oceanic crust at mid-ocean ridges.
Peridotite, believed to be the substance of the Earth's mantle is an igneous rock. It is mostly composed of olivine and pyroxene.

What is the heaviest rock in the world?
The heaviest rock in the world is thought to be a type of metamorphic rock called peridotite. Peridotite is found in the Earth's mantle and can be denser than other types of rocks due to its high iron and magnesium content.
What layer is Composed of peridotite?
The layer composed of peridotite is the mantle, which is located between the Earth's crust and core. Peridotite is the main rock type found in the upper mantle and is rich in minerals such as olivine and pyroxene.
What is the upper most mantle rock like?
The uppermost mantle rock is known as peridotite. It is composed mainly of the minerals olivine and pyroxene. Peridotite is denser than the rocks of the Earth's crust and is believed to be the main rock type in the upper mantle.
What rock does the upper mantle contain?
The upper mantle consists mainly of ultramafic rocks such as peridotite, which is rich in olivine, pyroxenes, and feldspar. These rocks are dense and typically dark in color due to their composition.
What rock contains high density minerals such as olivine?
Mafic, igneous rocks
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.

What is the upper most mantle rock like?
The uppermost mantle rock is known as peridotite. It is composed mainly of the minerals olivine and pyroxene. Peridotite is denser than the rocks of the Earth's crust and is believed to be the main rock type in the upper mantle.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
Which earth layer is made of peridotite?
The Earth layer that is made of peridotite is the mantle. Peridotite is a type of rock rich in olivine and pyroxene minerals that primarily makes up the upper mantle beneath the Earth's crust.
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
What is an example of a ultramafic rock?
peridotite
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite has the lowest silica content among the rocks mentioned. It is a ultramafic rock composed mostly of olivine and pyroxene minerals, with very low silica content compared to the other rocks.
What is garnet peridotite?
Garnet peridotite is a type of rock that forms in the Earth's mantle and contains a high proportion of both garnet and peridotite minerals. It is commonly found in subduction zones where oceanic plates are forced beneath continental plates. Garnet peridotite is important in understanding the processes that occur in the Earth's mantle.
What rock does the upper mantle contain?
The upper mantle consists mainly of ultramafic rocks such as peridotite, which is rich in olivine, pyroxenes, and feldspar. These rocks are dense and typically dark in color due to their composition.
What rock contains high density minerals such as olivine?
Mafic, igneous rocks
