Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust.ntrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by pre-existing rock (called country rock); the magma cools slowly and, as a result, these rocks are coarse grained. The mineral grains in such rocks can generally be identified with the naked eye.
Magma. Magma is the term used to describe molten material within the Earth; in simple terms: molten rock. But the molten rock usually contains some suspended crystals or dissolved gases. Igneous rocks form through the crystallization of magma.here is a considerable range of melting temperatures for different compositions of magma. Upon cooling from the completely molten state, it is typical for silicon tetrahedra to form first, and they in turn join with each other and other ions to form the nuclei for crystal growth.
