Ultramafic igneous rock contains the least silica.

∙ 13y agoBasalt has the lowest silica content among the common igneous rock types. It is classified as a mafic rock due to its relatively low silica content and high levels of iron and magnesium.
No, intermediate magma typically contains a moderate amount of silica compared to other magma types. Basaltic magma has the lowest silica content, while rhyolitic magma has the highest silica content.
Igneous rocks with low viscosity tend to have high silica content. Silica-rich magma leads to the formation of rocks like rhyolite, which have lower viscosity compared to silica-poor magmas like basalt. So, the silica content in igneous rock of low viscosity is generally high.
Silica is silicon dioxide, the most common component found in rocks and minerals. The composition of different types of magmas are assessed partly based on silica content, or the amount of silica in them. This content significantly affects how the lava behaves.
Light colored igneous rocks have a higher silica content and are known as felsic rocks. They have a lower density and are more common in continental crust. These rocks tend to be rich in minerals like quartz, potassium feldspar, and muscovite.
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.
No, intermediate magma typically contains a moderate amount of silica compared to other magma types. Basaltic magma has the lowest silica content, while rhyolitic magma has the highest silica content.
The mineral composition (silica content) is the chemical property most commonly used to classify igneous rocks. This can help differentiate between different types of igneous rocks, such as basalt, andesite, and granite.

No. Silica is not a rock; it is a component of many minerals found in all three rock types.

Felsic rocks are light-colored and have high silica content, while mafic rocks are dark-colored and have low silica content. Intermediate rocks fall in between felsic and mafic in terms of color and silica content. This difference in composition leads to variations in mineral composition, density, and melting temperature between the three types of igneous rocks.
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.

These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.

The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
