What is Composed of peridotite?
Peridotite is mainly composed of olivine, along with pyroxenes and minor amounts of other minerals like spinel and garnet. These minerals give peridotite its characteristic green color.
What is the lower layer of the mantle composed of?
The lower layer of the mantle is composed of solid rock that is under high pressure and temperature conditions. This layer is known as the lower mantle and is made up of silicate minerals such as peridotite and olivine. It plays a significant role in Earth's mantle convection and the movement of tectonic plates.
What rock forms the mantle layer?
The mantle layer is primarily composed of silicate rock called peridotite, which is rich in minerals like olivine and pyroxene. These minerals have high melting points and are able to withstand the high temperatures and pressures found in the mantle.
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.
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 Composed of peridotite?
Peridotite is mainly composed of olivine, along with pyroxenes and minor amounts of other minerals like spinel and garnet. These minerals give peridotite its characteristic green color.
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.
What is the lower layer of the mantle composed of?
The lower layer of the mantle is composed of solid rock that is under high pressure and temperature conditions. This layer is known as the lower mantle and is made up of silicate minerals such as peridotite and olivine.

Is peridotite composed primarily of olivine and pyroxene?
yes it is made up of olivine and various pyroxenes
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.
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.
Peridotite is composed almost entirely of dark sillicate mineralsits chemical composition is referred to as?
Peridotite is composed almost entirely of dark silicate minerals, primarily olivine and pyroxene. Its chemical composition is referred to as ultramafic, containing high levels of magnesium and iron.
Much of the upper mantle thought to be made of granite true or false?
False. The upper mantle is believed to be composed primarily of peridotite.
Which types of igneous rocks are composed of at least 50 percent olivine?
Peridotite and dunite are examples of igneous rocks that are composed of at least 50 percent olivine. Olivine is a common mineral in these ultramafic rocks, giving them their distinctive color and composition.
What is the extrusive equivalent of peridotite?
It's very rare to have an extrusive Peridotite, but under the right conditions Komatite can form. It's similar in appearance to Basalt, but has long ( anywhere between 1-10 cm) criss-crossing needles of olivine or pyroxene.
