WebMagma is a mixture of liquid rock, crystals, and gas. Characterized by a wide range of chemical compositions, with high temperature, and properties of a liquid. Magmas are less dense than surrounding rocks, and will therefore move upward. If magma makes it to the surface it will erupt and later crystallize to form an extrusive or volcanic rock. WebFluxes like water, boron, phosphorus, fluorine etc. can strongly reduce melting point. E.g. dry haplogranite barely melts at 700 Celsius while some pegmatite melts with extreme water and volatiles content can obviously exist bellow 500 Celsius. Dry anorogenic granites or ryolites have much higher melting point then some wet S-type granites.
