Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava.The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.Typically, the melting is caused by one or more of 3.4 Classification of Igneous Rocks As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic.

There is no general agreement amongst penologists as to the classification of igneous rocks. The lack of unanimity arises partly from the different bases of classification which have been proposed, and partly from misapprehensions as to the aims of classification.

The IUGS Subcommission on the Systematics of Igneous Rocks has been formed in order to review classification and nomenclature of igneous rocks and to present proposals to IUGS. Up to the present, the Subcommission has been concerned with plutonic rocks. Classification of igneous rocks can be based on their predominant grain size. Three types of rock can be identified: Volcanic rocks: solidify close to the Earth's surface. Because they cool quickly they have a finer-grained matrix (called groundmass). They may contain some larger crystals that formed earlier further down (called phenocrysts).
