Best Answer: It depends on the rock, but typically about 600 C (1100 F) to 1200 C (2200 F). Quartz or quartz rich rocks have the lowest melting point, and basaltic ...
Magma 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.t any given pressure and for any given composition of rock, a rise in temperature past the solidus will cause melting. Within the solid earth, the temperature of a rock is controlled by the geothermal gradient and the radioactive decay within the rock.
