Magma formation depends on the type of environment it is formed.
What is granitic magma rich in.
Magma is typically found several kilometers from the surface of the earth or in areas.
Rainier which sit above subduction zones today.
First of all you should know the difference between lava and magma magma and lava are both molten liquid rock but magma is moltenrock produced underneath earth surface while it magma erupts on the surface of earth it is called lava.
Magma or hot molten rock beneath the earth s surface has an average temperature of around 1300 degrees f to 2400 degrees f or 700 degrees c to 1300 degrees c.
Consequently a chemical classification is widely accepted and employed by most petrologists.
The issue of the origins and evolutionary mechanisms of granitic magmas is a vast subject.
Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
This is the silica rich magma that is often violently expelled from the large volcanos like mt.
Trace element modeling suggests that such variations can be explained by k feldspar controlled crystal melt separation in a k rich granitic magma.
Strictly speaking granite is an.

Granite definition a coarse grained igneous rock composed chiefly of orthoclase and albite feldspars and of quartz usually with lesser amounts of one or more other minerals as mica hornblende or augite.
Owing to the aphanitic texture of volcanic and hypabyssal rocks their modes cannot be readily determined.
As the k feldspar granites represent the residual crystal mush the ba isotope data of the coexisting ba bearing minerals can impose critical constraints on crystal melt separation.
Igneous rock igneous rock classification of volcanic and hypabyssal rocks.
Saint helens and mt.
Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.
The resulting magma is less dense than material typically found at that depth so it rises like oil in salad dressing.
Komatiite magma in particular can reach the temperature of 1600 degrees celsius.
The focus on the lfb is appropriate as this is the type locality for s and i type granites.
One popular scheme is based on the use of both chemical components and normative mineralogy.
