Rhyolite is a volcanic rock formed when highly viscous magma rich in silica erupts. In many cases rhyolite comes in the form of tuff, formed when the material is blasted out explosively, forming ash and pumice which eventually settle to the ground. Sometimes this tuff is so hot it gets welded into a solid rock. In other cases it erupts as lava. This lava will either form extremely thick lava flows or pile up on the vent as a lava dome.
What else can I help you with?
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
Is Rhyolite Porphyry an intrusive or extrusive rock?
Rhyolite Porphyry is an intrusive rock, formed from the slow cooling of magma underground. It is characterized by large crystals (phenocrysts) surrounded by a fine-grained matrix.
Is rhyolite formed at convergent plate boundaries?
Rhyolite can form at convergent plate boundaries where magma is generated from the melting of continental crust material being subducted. Subduction zones can provide the necessary conditions for the production of rhyolitic magma, resulting in the formation of rhyolite.
What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
Is orbicular rhyolite a metamorphic rock?
No, orbicular rhyolite is not a metamorphic rock. It is a type of igneous rock that forms from the cooling of silica-rich magma. Orbicular rhyolite is characterized by its spherical clumps of minerals, giving it a distinctive appearance.
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
What is an extrusive igneous rock?
Rhyolite
How destructive is a volcano?
The volcano is destructive by the magma inside it. The substance called "rhyolite" or "sticky magma" that is filled has so much gas in it, it pushes up. Because the magma is sticky, the lava gets harder and harder to push up and basically turns into an explosive volcano. The magma seeps through towns, destroying buildings and killing people.
Is Rhyolite Porphyry an intrusive or extrusive rock?
Rhyolite Porphyry is an intrusive rock, formed from the slow cooling of magma underground. It is characterized by large crystals (phenocrysts) surrounded by a fine-grained matrix.
The volcanic equivalent of granite is?
The volcanic equivalent of granite is rhyolite. Both granite and rhyolite are composed mainly of light-colored minerals such as quartz and feldspar, but rhyolite forms from volcanic magma that cools quickly at the Earth's surface, resulting in a fine-grained texture.
Is rhyolite formed at convergent plate boundaries?
Rhyolite can form at convergent plate boundaries where magma is generated from the melting of continental crust material being subducted. Subduction zones can provide the necessary conditions for the production of rhyolitic magma, resulting in the formation of rhyolite.
What are the magma types in order of decreasing viscosity?
Most viscous Felsic magma i.e. rhyolite Intermediate magma i.e. andersite Mafic magma i.e. Basalt Ultramafic magma i.e. Komatiite Least viscous
Which rock takes a longer time to form rhyolite or granite?
Granite takes longer to form than rhyolite. Granite is an intrusive igneous rock formed from the slow cooling of magma deep within the Earth's crust, which can take millions of years. Rhyolite, on the other hand, is an extrusive igneous rock formed from the rapid cooling of lava at the surface, which occurs more quickly than the formation of granite.
What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
The extrusive counterpart of granite?
The extrusive chemical equivalent of intrusive granite is rhyolite.
Is orbicular rhyolite a metamorphic rock?
No, orbicular rhyolite is not a metamorphic rock. It is a type of igneous rock that forms from the cooling of silica-rich magma. Orbicular rhyolite is characterized by its spherical clumps of minerals, giving it a distinctive appearance.
When would rhyolite rock form?
Rhyolite refers to a pale fine-grained volcanic rock. It is formed when magma that would have formed granite managed to erupt onto the surface of the Earth.
