Igneous Minerals National Museum Wales

Igneous minerals form during the cooling and solidification of molten rock, or magma, produced at high temperatures (around 650 to 1200°C) beneath the Earth's 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.
