Melting Points of Rocks and Minerals
Melting Points of Rocks Igneous rocks form through the crystallization of magma.There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.
