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.
What else can I help you with?
Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
Does Krakatoa have felsic magma or mafic?
Krakatoa volcano typically has mafic magma, which is low in silica content and high in magnesium and iron. This type of magma tends to be more fluid and can lead to explosive eruptions due to the rapid release of gases.
How the composition of magma determines an eruption's characteristics?
Silica(te) rich magma is usually an explosive eruption. The explosiveness of an eruption depends on - a) Gases trapped within the magma at eruption b) The Silica content c) The fragility of the crater walls and/or the volcanic plug.
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.
Why are eruption of mafic magma are quiet while eruption of Felsic magma are explosive?
Mafic magma, which is low in silica content, has a lower viscosity, allowing gases to escape easily during an eruption, resulting in quiet flows. In contrast, felsic magma is high in silica, making it more viscous and trapping gases within. When pressure builds up in felsic magma, it can lead to explosive eruptions as the trapped gases are released violently. This fundamental difference in composition and viscosity accounts for the contrasting eruption styles.
Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
Does mafic magma explode?
Mafic magmas generally have lower viscosity and gas content compared to felsic magmas, so they tend to flow more easily rather than explode. However, in certain conditions where gas build-up is high and pressure is released rapidly, mafic magma may still explode, but it is less common than with felsic magmas.
Does Krakatoa have felsic magma or mafic?
Krakatoa volcano typically has mafic magma, which is low in silica content and high in magnesium and iron. This type of magma tends to be more fluid and can lead to explosive eruptions due to the rapid release of gases.
What do quiet lava eruptions generally result from?
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.
The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
How the composition of magma determines an eruption's characteristics?
Silica(te) rich magma is usually an explosive eruption. The explosiveness of an eruption depends on - a) Gases trapped within the magma at eruption b) The Silica content c) The fragility of the crater walls and/or the volcanic plug.
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.
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
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.
What eruption is worse mafic or silicic?
Eruptions involcing silicic or felsic magma are generally the worst. Eruptions of mafic material are usually effusive or only mildly explosive, producing cinders or lava flows. Eruptions of felsic material often produce large ash clouds and deadly pyroclastic flows.
Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
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.
What type of magma does a composite volcano have?
Composite volcanoes typically have andesitic magma, which is intermediate in composition between felsic and mafic magmas. This type of magma is more viscous than mafic magma, leading to explosive eruptions and the buildup of lava and ash layers that form the characteristic steep-sided cone shape of composite volcanoes.
