glass is not an option in mafic
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Mafic lava is hotter than felsic lava and therefore flows faster.
mafic lava is the KIND of lava produced in mount (mt) Fuji.
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
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.
Mafic lava
As a shield volcano, Mauna Kea erupts mafic lava.
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.
Mafic lava is more fluid and less viscous compared to felsic lava, which results in faster flows and smoother surfaces. It has a higher temperature and lower silica content, leading to less explosive eruptions and the formation of dark-colored rocks like basalt. Mafic lava typically originates from oceanic volcanoes and can cover large areas with thin, extensive lava flows.
Mafic
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
