Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
Is mafic magma explosive?
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.
Do composite cone volcanoes have mafic lava?
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava 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.

Is felsic magma eruptive?
Not usually. Because it is so viscous, felsic magma does not erupt as easily as mafic magma. While eruptions of felsic magma do occur, most felsic rocks are intrusive, meaning they solidify underground.

Does Krakatoa have felsic magma or mafic?
felsic
Is sandstone felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Marble is a metamorphic rock composed of carbonate minerals. The terms mafic and felsic do no apply to it.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Is amphibolite mineral a felsic mafic or intermidate?
Is mineral amphibolite a felsic, mafic or intermidiate in term of color
What are the 3 common types of plutons?
Cinder volcanoes, composite volcanoes, frision volcanoes, and cinder cone volcanoes.
