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 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%.
As compared to ultramafic rocks mafic rocks have a?
greater proportion of silica
Magma that is relatively thin dark colored and low in silica?
This type of magma is called mafic magma. It has a low viscosity due to its low silica content, allowing gases to escape easily. It typically contains high levels of iron and magnesium, making it darker in color.
How does the silica content of an intermediate rock compare with that of felsic and mafic rock?
Intermediate rocks have a silica content that falls between felsic and mafic rocks. Felsic rocks typically contain more than 65% silica, while mafic rocks generally have less than 55%. Intermediate rocks usually contain about 55-65% silica, making them compositionally distinct and often resulting in different mineral content and characteristics compared to the other two rock types.

Is quartz mafic?
No, quartz is not mafic. Mafic minerals are rich in magnesium and iron, while quartz is a silicate mineral composed of silicon and oxygen. Quartz is classified as a felsic mineral due to its composition and low mafic content.
As compared to ultramafic rocks mafic rocks have a?
greater proportion of silica
Which rock has more silica granite or basalt?
Granite has more silica than basalt in it.
Is pumice in a example of a mafic igneous rock?
No, pumice is an example of a felsic igneous rock. Mafic rocks, like basalt, have lower silica content and higher iron and magnesium content compared to felsic rocks, like pumice, which have higher silica content and lower iron and magnesium content.

This type of magma is called mafic magma. It has a low viscosity due to its low silica content, allowing gases to escape easily. It typically contains high levels of iron and magnesium, making it darker in color.
What is the difference between felsic intermediate and mafic igneous rocks?
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
How does the silica content of an intermediate rock compare with that of felsic and mafic rock?
Intermediate rocks have a silica content that falls between felsic and mafic rocks. Felsic rocks typically contain more than 65% silica, while mafic rocks generally have less than 55%. Intermediate rocks usually contain about 55-65% silica, making them compositionally distinct and often resulting in different mineral content and characteristics compared to the other two rock types.
Does gabbro have a higher silica content than granite?
No, gabbro has a lower silica content than granite. Gabbro is classified as a mafic rock with silica content ranging from 45-52%, while granite is a felsic rock with higher silica content ranging from 65-75%.
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 type of magna has a low silica content?
Magma with low silica content is typically referred to as mafic magma. Mafic magma is characterized by its high temperature and low viscosity, which allows for the eruption of lava flows. This type of magma is commonly associated with basaltic rocks.
