It contains more than 68 weight of silica in composition and is granular and coarse grained in texture.

The volcanic fine grained compositional equivalent of granite.

It consists of the plagioclase feldspar minerals andesine and oligoclase together with one or more dark ferromagnesian minerals such as pyroxene and biotite. A vesicular rock also known as cinder. Andesite and diorite likewise refer to extrusive and intrusive intermediate rocks with dacite and granodiorite applying to those rocks with composition between felsic and intermediate. Rhyolite refers to the volcanic and felsic igneous rocks and granite refer to intrusive and felsic igneous rocks.

Friman wikimedia commons granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. Material consisting of rock glass ash and scoria ejected during violent volcanic eruptions. Granites and rhyolites compositionally equivalent to granite but of a fine grain size are composed mainly of orthoclase feldspar quartz plagioclase feldspar mica and amphibole. The fine grained volcanic equivalent of granite is basalt.

Andesite is the volcanic equivalent of diorite. An ultralight felsic vesicular rock. This chart illustrates the generalized mineral composition of igneous rocks. Its principal minerals are feldspars quartz and mica.
