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.


What type of rock is made of only pyroxene and olivine?

Peridotite is made only of olivine and pyroxene


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.


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 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.


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.


What is the upper most mantle rock like?

The uppermost mantle rock is Peridotite, which is mostly olivine and pyroxene but varies somewhat in chemical composition. Generally it is a coarse grained greenish rock. The name peridotite is derived from the gemstone peridot, which is pale green olivine.


Is much of the upper mantle made of granite?

No, the upper mantle is primarily composed of peridotite, a rock rich in the minerals olivine and pyroxene. Granite is more commonly found in the Earth's continental crust, not in the mantle.


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 igneous rock contains mostly pyroxene and olivine?

Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.


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.


Which mineral is present in much greater quanitites in peridotite than in gabbro?

Olivine is the mineral that is present in much greater quantities in peridotite compared to gabbro. Peridotite is rich in olivine, which gives it its characteristic green color, while gabbro contains less olivine and more dark minerals like pyroxene.
