∙ 9y agoMount St. Helens has produced rocks of mafic, felsic, and intermediate composition. The most recent activity has produced intermediate-felsic lava and pyroclastic material.

∙ 10y agoA shield volcano has mafic lava because the lava in the shield volcano has a low content of silica, resulting in low viscosity and a lot runnier lava than strato (composite) volcanoes.

∙ 11y agoAs a rule of thumb, massive crater-forming eruptions are usually associated with more felsic varieties of magma. Mount Mazama's magma is felsic.

Is mauna kea mafic or felsic?
As a shield volcano, Mauna Kea erupts mafic lava.
What type of lava does mauna loa have felsic-rhyolitic intermediate-andesitic mafic-basaltic?
Mauna Loa exhibits non-explosive eruptions (like many in the Hawaiian islands) in the form of low viscosity (more fluid) lava due to poor silica content.
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.
Does Krakatoa have felsic magma or mafic?

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.

Nationality of mauna loa?
Mauna Loa is a volcano in Hawaii.
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.
