What type of rock is rhyolite?
Rock Type: igneous (extrusive/volcanic)#N#Composition: feldspar, quartz, mica, hornblend#N#Equivalent to: granite (intrusive/plutonic)#N#Environment: Rhyolite is formed by magma that has reached the Earth’s surface (lava) and therefore cools very quickly. Lava can explode out of a volcano and make pumice or ash, or flow down its side and make thick layers of fine grained rock or volcanic glass.#N#Distinguishing Characteristics: Very fine grained, pinkish-grey, sometimes with dark streaks. If dipped in water and rubbed on a piece of paper, rhyolite will likely tear the paper rather than leave a muddy streak.#N#Origin of your Samples: Timmins, Ontario#N#Uses: Black volcanic glass called obsidian and frothy-looking white coloured rock called pumice are other forms of rhyolite. Pumice is used in abrasives, concrete, stone-washing laundries, hand soap, emery boards, and sandpaper and is used in sandblasting.

Where does igneous rock come from?
This type of igneous rock originates when lava erupts very rapidly from deep in the Earth's mantle, leaving behind a narrow pipe of this greenish brecciated rock. The rock is of ultramafic composition—very high in iron and magnesium—and is largely composed of olivine crystals in a groundmass consisting of various mixtures of serpentine, carbonate minerals, diopside, and phlogopite. Diamonds and many other ultra-high pressure minerals are present in greater or lesser amounts. It also contains xenoliths, samples of rocks gathered along the way.

Granodiorite differs from diorite by the presence of quartz, and the predominance of plagioclase over alkali feldspar distinguishes it from granite.

The random orientation of grains shows that this is a plutonic rock.

What is intrusive rock?
By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.

What happens when dioritic rock erupted from a volcano?
If a dioritic rock erupted from a volcano (that is, if it is extrusive), it cools into andesite lava. In the field, geologists may call a black-and-white rock diorite, but true diorite is not very common. With a little quartz, diorite becomes quartz diorite, and with more quartz it becomes tonalite.
Is felsite a mineral?
Felsite is fine-grained but not glassy, and it may or may not have phenocrysts (large mineral grains). It is high in silica or felsic, typically consisting of the minerals quartz, plagioclase feldspar, and alkali feldspar. Felsite is usually called the extrusive equivalent of granite. A common felsitic rock is rhyolite, which typically has phenocrysts and signs of having flowed. Felsite should not be confused with tuff, a rock made up of compacted volcanic ash that can also be light colored.
