Mafic magma can be involced in both explosive and non-explosive eruptions.
Mauna Loa volcano in Hawaii typically has mafic magma, which is rich in magnesium and iron, resulting in low viscosity and flowing lava. This magma composition contributes to the shield volcano shape and frequent eruptions on Mauna Loa.
Magma with low silica content is called mafic magma. It is characterized by its high temperature, low viscosity, and dark-colored minerals like olivine and pyroxene. Mafic magma typically erupts from shield volcanoes and is associated with basaltic rocks.

Mafic minerals generally have a relatively high density compared to felsic minerals. This is because mafic minerals are rich in iron and magnesium, which are denser elements. As a result, rocks rich in mafic minerals like basalt and gabbro tend to be heavier and denser than rocks composed of felsic minerals like granite.
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
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.
Like most cinder cones Paricutin was fed by mafic magma.
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.
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
Mafic magma is high in magnesium and iron, has a low silica content, and is less viscous compared to felsic magma. Mafic lava typically produces dark-colored rocks like basalt and is associated with oceanic crust. Mafic magma tends to erupt more quietly and flow more easily due to its lower viscosity.
The two main types of magma are mafic and felsic.
Not usually. Mafic magma usually has a low gas content than felsic or intermediate magma, so eruptions are often effusive. Cinder cones primarily erupt mafic lava with a low level of explosivity. Explosive eruptions can also occur if the magma comes in contact with groundwater.
