The rock rhyolite is the chemical equivalent of granite, but formed on the surface, making it an extrusive igneous rock. Intrusive rocks have larger crystals.

Can one magma produce several different igneous rocks having different minerals?
Absolutely, yes!
A decorative use for rocks and minerals?
Igneous
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
Why are dark colored igneous rocks heavier than light colored ones?
As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent. As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.
What minerals are in welded tuff?
