what is the temperature range for magma?
By definition, all igneous rock is formed from magma. Magma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range 700Â°C to 1300Â°C, but very rare carbonate melts may be as cool as 600Â°C, and komatiite melts may have been as hot at 1600Â°C. Most are silicate solutions. It is capable of intrusion into adjacent rocks or of extrusion onto the surface as lava or ejected explosively as tephra to form pyroclasic rock. Environments of magma formation and compositions are commonly correlated.
