May 18, · Rhyolite. Rhyolite is a felsic (silicarich) volcanic igneous rock with the same mineral content as granite, only unlike granite, it cools fast from the molten rock near or over the surface of Earth's crust (extrusive type).When these magmas erupt, a rock with two grain sizes typically forms. The larger crystals that form just beneath the surface cool at a slower pace and are known as phenocrysts.

Learn About Rocks

Rocks are combinations of one or more minerals that we find in nature. Basalt is commonly composed of three minerals – feldspar, pyroxene, and olivine. Granite is commonly composed of five minerals – two kinds of feldspar, mica, amphibole, and quartz. Just like minerals, there are many different kinds of rocks.
