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.

Do non silicate minerals contain silicon?
Most likely not. Silicate minerals contain silicon in combination with oxygen. However, silicon itself is considered a non-silicate mineral, composed entirely of the element silicon; without the oxygen, however, it IS a non-silicate mineral.
What type of rock is peridotite?
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.
What do silicate minerals contain?
They all contain the silicon-oxygen tetrahedron.

What are chief elements in igneous rock?
Igneous rocks are composed mainly of silicate minerals. Granite is mostly quartz, feldspar and mica. Basalt is mainly feldspar, pyroxine and amphibole. Diorite can be a mixture of all of these minerals. Peridotite is mainly olivine (peridot) and pyroxine.
Does carbonate contain silicate?
No, carbonate does not contain silicate. Carbonate minerals are composed of carbon and oxygen ions, while silicate minerals are composed of silicon and oxygen ions.

It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
What is the percentage of the earths crust made up of non silicate minerals?
Only 10% of the Earth's crust is composed of non-silicate minerals. Examples of non-silicate minerals are barringerite, nickel phosphide, taenite and suessite.
Are carbonates and halides silicate or non silicate?
Carbonates and halides are non-silicate minerals. They do not contain silicon and oxygen tetrahedra as the primary building blocks, unlike silicate minerals. Carbonates are composed of carbon and oxygen atoms, while halides are composed of halogen ions, such as fluoride, chloride, bromide, or iodide.
Is chalcedony silicate or nonsilicate?
Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silicate minerals.
