What else can I help you with?
Is peridotite composed primarily of olivine and pyroxene?
yes it is made up of olivine and various pyroxenes
Which minerals is rarely found in felsic igneous rocks?
they are found in approximetily 90 %in the earth crust
Are metamorphic rocks the most commonly found on Earth's surface?
No. The most common rock found on the surface of the Earth is sedimentary rock, and in particular, shale, sometimes referred to as mudrock).
What is the height of the earth's crust?
The highest point of the Earth's crust is to be found at the top of Mt. Everest which has an elevation of 8,848 metres.
Are igneous rocks the rarest rocks found on earth?
Apples are cool
Where can you find peridotite?
Peridotite is typically found in the upper mantle of the Earth. It can also be found in ophiolite complexes, which are sections of oceanic crust that have been uplifted and exposed on land through tectonic processes. Additionally, peridotite can sometimes be found in areas of ancient continental crust that have been deeply eroded.
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 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.
Where is peridotite found?
Peridotite is a dense, coarse-grained plutonic rock that contains a large amount of olivine. Spinel-bearing peridotites and plagioclase-bearing peridotites are foliated.
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.
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 intrusive or extrusive?
Peridotite is an intrusive igneous rock, meaning it forms below the Earth's surface from the slow cooling of magma. It is primarily composed of olivine and pyroxene minerals, and is commonly found in the upper mantle.
What is the chemical formula of peridotite?
The chemical formula of peridotite is typically described as (Mg, Fe)2SiO4, which represents the main mineral components olivine and pyroxene. It is a common rock found in the Earth's upper mantle.
Does the earth's mantle contain peridotite?
Yes it does.
What is the peridotite use?
Peridotite is primarily used as a source of olivine, a mineral found within it, which is used in industries such as refractory materials, foundry molds, and as a gemstone called peridot. Additionally, peridotite has been studied for its role in the Earth's mantle dynamics and its potential as a carbon sequestration agent to mitigate climate change.
What is unusual about peridotite and dunite?
Peridotite and dunite are both ultramafic rocks that contain high concentrations of olivine, a green mineral. The unusual aspect is that they have very low silica content compared to other types of rocks, making them chemically distinct. Additionally, peridotite and dunite are commonly found in the Earth's mantle, which is beneath the Earth's crust, rather than at the surface.
Peridotite is composed almost entirely of dark silicate minerals.?
Peridotite is a coarse-grained, dense igneous rock composed mainly of olivine and pyroxene minerals. It is typically green in color due to the high concentration of olivine. Peridotite is commonly found in the Earth's upper mantle and is important in the formation of oceanic lithosphere.
