Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
mafic lava is the KIND of lava produced in mount (mt) Fuji.
Paricutin volcano in Mexico predominantly erupted mafic lava, which is rich in magnesium and iron and has a low silica content. This type of lava tends to flow more easily compared to felsic lava.
Mauna Loa is considered a mafic volcano. It erupts basaltic lava, which is characteristic of mafic compositions with low silica content and high magnesium and iron content.
Oh, dude, Mt. Etna has both mafic and felsic lava. It's like a lava buffet up there! Mafic lava is low in silica and more runny, while felsic lava is high in silica and thicker. So, yeah, Mt. Etna serves up a mix of both, keeping things interesting for all the volcano enthusiasts out there.
Mafic lava is hotter than felsic lava and therefore flows faster.

As a shield volcano, Mauna Kea erupts mafic lava.
it has mafic and felsic duhhhhh
== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
Mafic lava can become felsic lava through a process called fractional crystallization. As the magma cools, minerals within it crystallize at different temperatures, causing the remaining liquid to become more silica-rich and compositionally evolve to felsic lava. This process occurs deep within the Earth's crust during magma chamber cooling.
Mafic lava is low in silica and high in iron and magnesium, which makes it less viscous and more fluid compared to felsic lava. It tends to flow easily and often forms basaltic rocks when it cools. Mafic lava eruptions typically result in gentle, effusive lava flows rather than explosive eruptions.
Composite cone volcanoes typically have more intermediate to felsic lava compositions, which are higher in silica content compared to mafic lava. This results in a more viscous lava that typically leads to explosive volcanic eruptions. Mafic lava is usually associated with shield volcanoes, which have gentler slopes and more fluid lava flows.
