What kind of volcanic eruption happens when granite magma is present?
Wiki User

Granitic magma is highly viscous, meaning it has a high resistance to flow. Granitic magma does not reach the surface very often. It cools underground, thus we have granite. If granitic magma actually reaches the surface it would result in a highly explosive eruption.

∙ 12y agoAn explosive one: granite forms viscous lava, and forms a hard plug inside the volcano, and when pressure below the plug is substantial enough, the volcano blows. Big time. This varies in interpretation, so it could be Plinian, if you want a specific term, but overall, the eruption is very violent, and the violence and scale varies from case to case.

Where are granite rocks normally found?
normally found in a volcanic eruption zone where carbon is present
What kind of volcanic material is present in a volcanic eruption?
pikatela
Which of these substances is usually not present in explosive volcanic eruptions?
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
What are the two factors that affect the explosiveness of a a volcanic eruption?
There are two factors that determine how explosive a volcano is. The two factors are the amount of gas that is present in the lava and how easy or difficult that gas can be released into the atmosphere.
What is the mineral presents of granite?
The essential minerals are Quartz, Felspar and Mica. Accessory minerals may alsobe present but all the three above must be present for the rock to be a granite.

What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
Are there any supervolcanoes on mars?
At present there is no observed volcanic activity of Mars. The super volcano of Olympus Mon on Mars is thought to be inactive, dating its past eruption from several to 15+ million years ago.
Are mountains made out of limestone?
They can be. Most mountain ranges form when the land is thrust upward by tectonic activity, so the type of rock present depends on what rock is present to begin with. The cores of mountain ranges, though, are often made of granite and gneiss. Volcanic mountains are not made of limestone.

What eruption occurs when basaltic magma is present?
quiet
Which minerals are present in granite but are never present in gabbro?
Never say never, but it's mica.
What is the example of quiet and violent eruptions of volcano?
An example of a "quiet" eruption would be the 1983-present eruption of Kilauea in Hawaii. A violent eruption would be the 1980 eruption of Mount St Helens.
Which volcanic features are present on Mount Krakatoa?
nothing
