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.
Filter-pressing, process that occurs during the crystallization of intrusive igneous bodies in which the interstitial liquid is separated from the crystals by pressure. As crystals grow and accumulate in a magmatic body, a crystal mesh may be formed, with the remaining liquid distributed in the interstices. This mesh may result from crystals that sink to the floor of the magma chamber or from crystals that accumulate during the advanced stages of crystallization of the body.
