Peridotite and dunite are examples of ultramafic igneous rocks primarily composed of the mineral olivine. Peridotite typically contains a mix of olivine, pyroxenes, and possibly other minerals, while dunite is almost entirely made up of olivine. These rocks are commonly found in the Earth's mantle and are significant in understanding tectonic processes and the composition of the Earth's interior. Their formation is associated with high-temperature and high-pressure conditions beneath the Earth's surface.
What else can I help you with?
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
Which one of these is an igneous rock is it gabbro obsidian peridotite or chert?
Gabbro, obsidian, and peridotite are examples of igneous rocks. Chert is a sedimentary rock formed from the accumulation of silica-rich microorganisms or chemical precipitation, not from the cooling and solidification of molten magma like igneous rocks.
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 is the composition of the outer mantle?
peridotite
Can I get more examples of igneous rocks?
Peridotite, andesite, pumice, rhyolite, obsidian, granite, and basalt.
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
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 the protolith is of serpentine?
peridotite
Which one of these is an igneous rock is it gabbro obsidian peridotite or chert?
Gabbro, obsidian, and peridotite are examples of igneous rocks. Chert is a sedimentary rock formed from the accumulation of silica-rich microorganisms or chemical precipitation, not from the cooling and solidification of molten magma like igneous rocks.
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 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.
What are some some forming minerals?
There are many rock forming minerals but some examples are peridotite,gabbro,basalt etc.Olivine is used in jewellery and a rock forming mineral.
What is the composition of the outer mantle?
peridotite
What is an example of a ultramafic rock?
peridotite
