Igneous minerals form during the cooling and solidification of molten rock, or magma, produced at high temperatures around 650 to 1200176C beneath the Earths surface. Which minerals crystallize from the magma is influenced by factors such as its chemical composition, the temperature of crystallization, and the rate of cooling.
