Magma often collects in magma chambers that may feed a volcano or solidify underground to form an intrusion. Magma is capable of intrusion into adjacent rocks (forming igneous dikes and sills), extrusion onto the surface as lava, and explosive ejection as tephra to form pyroclastic rock.emperatures of most magmas are in the range 700 Â°C to 1300 Â°C (or 1300 Â°F to 2400 Â°F), but very rare carbonatite magmas may be as cool as 600 Â°C, and komatiite magmas may have been as hot as 1600 Â°C. Most magmas are silicate mixtures.
Magma (from Greek Î¼Î¬Î³Î¼Î±, thick unguent) is a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals, dissolved gas and sometimes gas bubbles.agma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range 700 Â°C to 1300 Â°C (or 1300 Â°F to 2400 Â°F), but very rare carbonatite magmas may be as cool as 600 Â°C, and komatiite magmas may have been as hot as 1600 Â°C. Most magmas are silicate mixtures.
