Basicaly strombolian vocanic eruption is basaltic , it have lage amount of Fe and Mg . it have no or very low amount of silica
If you have a quiet eruption you have low silica.

If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.

There are three types of magma that contains silica. Basaltic Magma has 50 percent silica, Andesitic Magma has 60 percent silica, and Granitic Magma has 70 percent silica.
