It contains about 70% Silica(SiO2)
Added:
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.
What else can I help you with?
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
What was the population Composition 2011 India?
Give a long note on :Population Composition Of India in 2011
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 is magma composition of Mount Tambora?
It is that it has high silica content
What melts to form rhyolitic magma?
Rhyolitic magma is typically formed from the melting of continental crust rocks such as granite and other felsic rocks. These rocks have high silica content, which contributes to the high viscosity of rhyolitic magma. Magma properties can also be influenced by other factors such as water content and temperature.
What are the 3 types of magma?
basaltic magma ,Andesitic magma and Rhyolitic magma
Does Rhyolitic magma forms beneath continental or oceanic crust?
Rhyolitic magma typically forms beneath continental crust due to high silica content and low temperature. The silica-rich composition leads to viscous magma, which is more common in continental settings compared to oceanic crust where magma tends to be more basaltic and less viscous.
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.
The average composition of rocks comprising a large composite cone or stratovolcano is similar to what magma?
The average composition of rocks in a large composite cone or stratovolcano is similar to andesitic magma. Andesitic magma is intermediate in composition between basaltic and rhyolitic magma, containing elements such as silica, magnesium, and iron. This magma type is responsible for the explosive eruptions characteristic of stratovolcanoes.
How many types of magma are there?
their are many types of magma because when a volcano has soft magma that means it either exploded small or the magma was going really slow and fast magma and big exploding volcano's are hard magma.:)
What list places the magma What list places the magma types in order of decreasing?
basaltic,andesitic,rhyolitic
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
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.
