Igneous rock (derived from the Latin word ignis that means fire), or magmatic rock, is one among the 3 main rock sorts, the others being matter and metamorphic. stone is made through the cooling and hardening of stone or volcanic rock.

The stone are often derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or additional of 3 processes: a rise in temperature, a decrease in pressure, or a modification in composition. hardening into rock happens either below the surface as intrusive rocks or on the surface as eruptive rocks. stone might kind with crystallization to make granular, crystalline rocks, or while not crystallization to make natural glasses.

Igneous rocks occur during a big selection of geologic settings: shields, platforms, orogens, basins, massive igneous provinces, extended crust and oceanic crust.
