Basalt.Vesicular texture describes an aphanitic rock characterized by preservation of cavities (vesicles) originally filled by escaping gases. Highly vesicular basalts (low-silica magma) are called scoria, whereas highly vesicular rhyolite (high-silica magma) is known as pumice
What else can I help you with?
What does low silica magma form?
Nealy all magma on Earth is originally low-silica, mafic magma. Most magma originates from the upper mantle, which is ultramafic, meaning it has a very low silica content. This rock may partially melt under certain conditions, forming mafic magma, which has a somewhat higher silica content than the mantle rock.
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
Where do mafic and felsic magma originate?
Felsic is a term that means that a rock contains types of silica. Fesic magma is magma that is high in silica particles and low in iron particles.
Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily
What does low silica magma form?

This rock may partially melt under certain conditions, forming mafic magma, which has a somewhat higher silica content than the mantle rock.
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
Which flows easier high silica magna or low silica magna?
Low silica magma typically flows easier than high silica magma because low silica magma has lower viscosity, meaning it is less resistant to flow. High silica magma is more viscous due to the presence of more silica tetrahedra in its composition, making it thicker and more difficult to flow.
Material found in magma that formed from oxygen and silicon?
Silica yes! because when lava from the magma chamber rises toward the top of the volcano the lava or silica it depends on the hot ness of high silica or low silica!!!! :D
What is the relationship between magma and minerals?
No, magma is molten rock, and it is a semi liquid that exists below the surface (when it's above the surface, it's called lava). When magma cools underground it becomes an intrusive igneous rock which is composed of combinations of various minerals.

Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
Does AA lava have a lot of silica?
no. AA has a relatively low silica content level.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.
