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 rock will you find in the Mantle?
The mantle, or interior of the Earth is made up of mostly of rocks that have high amounts of silicon and aluminum. There is also an abundance of nickel and iron in the 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 mineral is present in much greater quantities in peridotite than in gabbro?
The mineral olivine is present in much greater quantities in peridotite compared to gabbro. Olivine is a common mineral in peridotite and gives it its characteristic green color, while gabbro contains less olivine and more plagioclase feldspar.
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.
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 type of rock is mostly found in mantle?
The rocks found in the mantle are usually olivine, pyroxenes, spinal structure minerals, and garnet. Some others are peridotite, dunite, and eclogite.
What is the parent rock for Serpentine?
The parent rock for Serpentine is ultramafic rock, such as peridotite or dunite. Serpentine forms through the metamorphism of these ultramafic rocks under high pressure and temperature conditions.
Why dunite has no volcanic equivalent?
Dunite is a type of peridotite rock that is formed deep within the Earth's mantle through processes like partial melting. Its composition and formation conditions do not correspond with those found in volcanic settings, which is why dunite does not have a volcanic equivalent. Instead, dunite is typically brought to the surface through tectonic processes like uplift and erosion.
What are rocks that come from the mantle?
Rocks that come from the mantle are called mantle rocks. These rocks are typically formed deep within the Earth's mantle and can include peridotite, dunite, and eclogite. Mantle rocks are brought to the surface through processes like volcanic eruptions or tectonic movements.
What are the five rocks?
There are far beyond 5 igneous rocks. Among them, there is: Pumice Obsidian Andesite Basalt Diorite Gabbro Granite Pegmatite Peridotite Rhyolite Scoria Tuff Porphyry Anorthosite Vesicular Dunite

What type of rock is created from sedimentary or igneous?
Conglomerate, Sandstone, Shale, Coal Seams, Limestone and Gypsum rock are Sedimentary rocks, while Granodiorite, Granite, Syenite, Diorite, Gabbro, Peridotite and Dunite are Igneous rocks.
Is dunite or olivine a common rock?
Dunite is not a common rock but olivine is.
Type of igneous rock containing more magnesium than aluminum is?
Ultramafic igneous rock. These rocks have high magnesium and low silica content, making them rich in minerals like olivine and pyroxene. Examples include peridotite and dunite.
What are examples of igneous rock?
nothing
