What is the composition of granite?

Answer 1

Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.

Answer 2

Granite's mineral composition is mainly quartz and feldspar. Approximately 80 percent of this igneous rock is made up of these two minerals, The other minerals found in granite are mica and amphibole.

Answer 3

Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.

Answer 4

Granite is a hard, coarse-grained rock that makes up most of the Earth's rocky surface. It mainly consists of three minerals: quartz, alkali feldspar and plagioclase feldspar. It also has small amounts of hornblende and biotite mica.

Answer 5

Granite is composed primarily of quartz, feldspar and mica.

It is a widely occurring group of intrusive, igneous rocks that form at great depth and pressure under continents.
