The Volcanic Fine Grained Compositional Equivalent Of Granite

The fine grained volcanic equivalent of granite is basalt.

The volcanic fine grained compositional equivalent of granite.

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. It consists of the plagioclase feldspar minerals andesine and oligoclase together with one or more dark ferromagnesian minerals such as pyroxene and biotite. Andesite is the volcanic equivalent of diorite.

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. Its principal minerals are feldspars quartz and mica. An ultralight felsic vesicular rock. The fine grained equivalent of granite.

Rhyolite refers to the volcanic and felsic igneous rocks and granite refer to intrusive and felsic igneous rocks. This chart illustrates the generalized mineral composition of igneous rocks. A vesicular rock also known as cinder. It contains more than 68 weight of silica in composition and is granular and coarse grained in texture.
