It varies. The term lapilli is applied to pyroclastic material between 2 and 64 mm in size, which does not necessarily indicate anything about composition. It can range anywhere from mafic to felsic, with silica content ranging from 45% to over 70% silica.

What does silica content?
Any metrial or thing which containts silica in it is call silica content..
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
How does silica content and viscosity effect igneous rocks?
As silica content increases viscosity increases.
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
Correct. The lower the silica content, the more mafic the magma is.

What is the silica content of Stromboli?
Stromboli has a 53 to 54% silica content on average.
What is the silica content of magma that has low viscosity?
low silica content (basaltic magma)
What is silica content of magma that has a low viscosity?
low silica content (basaltic magma)

What is the silica content of quartz?
Silica is silicon dioxide, the most common component found in rocks and minerals. The composition of different types of magmas are assessed partly based on silica content, or the amount of silica in them. This content significantly affects how the lava behaves.
What is the silica content of magma that would result in pyroclastic flow?
it is normally intermediate flow because of the silica content.
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
