Is peridotite felsic mafic intermediate or ultramafic?
Peridotite is ultramafic, composed predominantly of mafic minerals such as olivine and pyroxene. It has low silica content and high magnesium and iron content, making it different from felsic, intermediate, and mafic rocks.
What igneous compositions has the lowest silica content mafic ultra mafic intermediate or felsic?
Mafic igneous compositions have the lowest silica content, followed by ultramafic compositions. Mafic rocks are rich in magnesium and iron and have silica contents ranging from 45-52%. Ultramafic rocks have even lower silica content, typically below 45%.
What two rocks type are niether felsic nor mafic?
The two rock types that are neither felsic nor mafic are ultramafic and intermediate. Ultramafic rocks contain very low silica content and are primarily composed of olivine and pyroxene, while intermediate rocks have a silica content between that of felsic and mafic rocks, typically consisting of a mix of plagioclase feldspar and amphibole. Examples of ultramafic rocks include peridotite, and examples of intermediate rocks include andesite.
This type of magma has low silica content?
Mafic magma has low silica content. It is usually rich in magnesium and iron, leading to its high density and fluid-like behavior. Mafic magmas tend to form basaltic rocks when they solidify.
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Is peridotite felsic mafic intermediate or ultramafic?
Peridotite is ultramafic, composed predominantly of mafic minerals such as olivine and pyroxene. It has low silica content and high magnesium and iron content, making it different from felsic, intermediate, and mafic rocks.

Examples of ultramafic rocks include peridotite, and examples of intermediate rocks include andesite.
What is ultamafic?
Ultramafic is a term used to describe igneous rocks made solely of mafic minerals.
What is the difference in ultramafic rocks and mafic rocks?
Ultramafic rocks like peridotite and dunite, are igneous rocks that have a very low silica content and very high levels of iron and magnesium. They are therefore more dense than most igneous rock and are found at great depth but appearing on the surface due to volcanic eruption.
Rocks that have high levels of iron and magnesium are called?
Igneous rocks with high iron and magnesium content are known as mafic. This word comes from the combination of the "Ma" for magnesium and Fe for iron, MaFe, Mafic
Does the mantle have mafic or felsic in it?
The mantle is ultramafic.

This type of magma has low silica content?
Mafic magma has low silica content. It is usually rich in magnesium and iron, leading to its high density and fluid-like behavior. Mafic magmas tend to form basaltic rocks when they solidify.
What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
