What else can I help you with?
Are pyroclastic flows felsic or mafic?
Pyroclastic flows can be of any composition, but are more commonly felsic or intermediate.
Does a composite volcano have felsic or mafic lava?
Volcanic eruptions range from explosive to quiet depending on the viscosity of the magma & the amount of dissolved gases. Felsite volcanoes are the most viscous & the most explosives. The explosive products from a volcano are called pyroclastic rocks. Thus the most explosive volcano are those whose composition is felsitic.This viscous felsite may plug the vocano, causing the pressure to build within it. When the pressure becomes great, an explosive eruption will occur. That is how composite volcoanos are formed.
Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
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 Pyroclastic rock basic or acid?
Pyroclastic material is more often felsic (acidic) or intermediate, but mafic (basic) pyroclastic material may also occur.
Are pyroclastic flows felsic or mafic?
Pyroclastic flows can be of any composition, but are more commonly felsic or intermediate.
What kind of lava does composite volcanoes produce AA or pahoehoe?
Usually neither. A'a and pahoehoe lavas are both of mafic composition (rich in iron and magnesium, poor in silica) and form basalt when they cool. Composite volcanoes usually erupt material of intermediate to felsic composition (felsic is rich in alkalis, aluminum, and silica), with lavas cooling into rocks such as andesite, dacite, and rhyolite.
What type of lava Mount Vesuvius?
Mt. Vesuvius produces felsic lava in a pyroclastic explosion.

Is mount Etna an explosive eruption?
Yes, Mount Etna does have explosive eruptions. This is because the eruption releases pyroclastic material, made up of felsic lava which is rich in silicate materials. Therefore, causing the giant explosion!
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Do the most violent volcanoes spew mafic?
No. The most violent eruptions involve felsic magma.
What kind of eruption is caused by Magmas with high silica content that is felsic magma?
Eruptions caused by magmas with high silica content, specifically felsic magma, are typically explosive in nature. This is due to the high viscosity of felsic magma, which traps gases until pressure builds up sufficiently to cause a violent release. As a result, these eruptions can produce pyroclastic flows and ash clouds, significantly impacting the surrounding environment. Examples include eruptions from volcanoes like Mount St. Helens and Mount Pinatubo.
