Yes. Many stratovolcanoes vary in the composition of what they erupt over time. They may cycle in the type of material. As the magma chamber cools, the magma somtimes becomes more felsic only to periodically receive and injection of fresh mafic magma from the mantle.

∙ 7y agoOn average composite volcanoes are intermediate, but the magma composition will actually vary over time and from one volcano to another. The full range of magma compositions can be found at some composite volcanoes.

Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
Is mauna kea mafic or felsic?
As a shield volcano, Mauna Kea erupts mafic lava.
Do composite cone volcanoes have mafic lava?
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
What kind of lava do Composite volcanoes produce?
it has mafic and felsic duhhhhh
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.

What is a Precambrian's shield?
How are mafic and felsic igneous rocks different

What is the comaprison of felsic and mafic?
Felsic minerals are Silicon-rich; whereas Mafic ones are low in Silicon, but contain Iron and Magnesium.
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
Do the most violent volcanoes spew mafic?
No. The most violent eruptions involve felsic magma.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Why are mafic rocks denser than felsic rocks?
Mafic rocks are denser than felsic rocks because they contain heavier compounds, minerals and other materials, they are ferromagnesian in composition.
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.
What type of rock makes shield volcanoes?
Shield volcanoes are formed from the extrusive igneous rock basalt.basalt
