The magmas extruded on the surface of the Earth originated by partial melting of a solid source that was transformed into a primary magma and a residuum. It appears that magmas were formed by partial melting during the main part of the Earth’s history, however, it is possible that the very first continental crust was formed by fractionation of magmas stemming from the oceans of magma that initially covered the Earth.
