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.

Is peridotite intrusive or extrusive?
Peridotite is an intrusive ultramafic igneous rock.
Where can you find peridotite?
peridotite is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. Peridotite can be found in the earth's mantle.

Peridotite is composed almost entirely of dark silicate minerals.?
A peridotite is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica.
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.
What rock does the upper mantle contain?
The dominant rock type of the upper mantle is peridotite.
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
What type of rock may be formed by fractional crystallization of olivine and pyroxene.?
Peridotite.
Where does a peridotite rock come from?
Peridotite originates from the upper mantle.
Is peridotite intrusive or extrusive?
Peridotite is an intrusive ultramafic igneous rock.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
What is an example of a ultramafic rock?
peridotite
