There are two known processes by which magma ceases to exist: by volcanic eruption, or by crystallization within the crust or mantle to form a pluton. In both cases the bulk of the magma eventually cools and forms igneous rocks.
Igneous rocks are formed by the cooling and crystallization of magma. The temperature of cooling determines which types of minerals are found in the rock and helps scientists classify the rock as felsic, intermediate or mafic. Rocks that begin their cooling at low temperatures are rich in minerals containing silicon, potassium and aluminum.
