Is rhyolite a rock or a mineral?

Rhyolite is defined as an extrusive igneous rock with the maximum silica content. It is generally glassy or fine grain in texture but maybe porphyritic, consisting of large mineral crystals, known as phenocrysts. The rhyolite rock is predominantly composed of minerals like quartz, sanidine, and plagioclase. It is an extrusive rock similar to granite.

How common is rhyolite?

Rhyolite has been found on islands far from land, but such oceanic occurrences are rare. The tholeiitic magmas erupted at volcanic ocean islands, such as Iceland, can sometimes differentiate all the way to rhyolite, and about 8% of the volcanic rock in Iceland is rhyolite.

Why is rhyolite an uncommon rock?

Rhyolite has a similar composition and appearance to granite. However, rhyolite forms as a result of a violent volcanic eruption, while granite forms when magma solidifies beneath the Earth's surface. Rhyolite is found all over the planet, but it is uncommon on islands located far from large land masses.

What is made of rhyolite?

Rhyolite is a volcanic rock. It is fine-grained because it forms by the rapid cooling of magma, usually when it erupts onto the Earth's surface. When rhyolite erupts quietly it forms lava flows. If it erupts explosively it often forms pumice.

How are rhyolites formed?

Associations of andesites, dacites, and rhyolites in similar tectonic settings and with similar chemistry suggests that the rhyolite members were formed by differentiation of mantle-derived basaltic magmas at shallow depths. In other cases, the rhyolite appears to be a product of melting of crustal sedimentary rock. Water vapor plays an important role in lowering the melting point of silicic rock, and some rhyolitic magmas may have a water content as high as 7–8 weight percent.

Why are rhyolitic magmas explosive?

Due to their high content of silica and low iron and magnesium contents, rhyolitic magmas form highly viscous lavas. As a result, many eruptions of rhyolite are highly explosive, and rhyolite occurs more frequently as pyroclastic rock than as lava flows.
