Rhyolite, a gost town town in South-Nevada, is named for rhyolite, an igneous rock composed of light-colored silicates, usually buff to pink and occasionally light gray. It belongs to the same rock class, felsic, as granite but is much less common.

Is pumice a foidolite rock?
Not necessarily. It is often andesitic or rhyolitic.
What does the term composition mean as it applies to igneous rock?
it can mean two things, (1)mineralogical composition or (2)Chemical composition

Does the composition of a sedimentary rock depend upon the composition of the rocks and the living things its sediments came from?
It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.
What is the difference between a composition and an essay?
The words 'composition' and 'essay' are often used interchangeably, as both are literary forms. An essay is a type of composition, but a composition doesn't always have to be in the form of an essay. A composition can be a poem, short story, argumentative essay, or research paper. An essay is more specific, as it is a personal piece on a specific topic.
Do volcanic bombs have a large amount of silica?
Not necessarily. Volcanic bombs may be formed from any composition of magma from basaltic to rhyolitic.
What melts to form rhyolitic magma?
Rhyolitic magma is a gas. The rhyolitic magma usually has to largest gas contents.
What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
What is Krakatau's magma composition?

Are geological features created by rhyolitic magma Rhyolitic magma promotes eruptions?
Lava domes are large geological features created by rhyolitic magma. Rhyolitic magma promotes plinian eruptions. Plinian eruptions can happen very quickly and shoot lave several miles into the air.
What type of lava flows the slowest?
Rhyolitic
What type of lava does Yellowstone caldera have?
Both rhyolitic and basaltic lava flows have been found in the Yellowstone Caldera. There are alro large deposits of rhyolitic tuff.
Will rhyolitic magmas erupt at lower temperatures than basaltic magmas?
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.
What rocks are in a shield volcano?
Basaltic, Andersitic, and Rhyolitic
How dangerous is rhyolitic lava?
because it's fresh
What is dactic lava composition?
I do not know specifically but it is fairly high in silica making it rather viscous and good for trapping/holding gas. Dactic magmas can be either exlposive volcanic events or just be mild lava flow depending on the amount of trapped gas. Dactic sits between Rhyolitic and Andisitic in compostion. Rhyolitic is highest in viscosity have the most Silica then Dactic, andesitic then basaltic having the least silica.
What are three different types of lava?
Basaltic, andesitic and rhyolitic
