High temperature fractional crystallization of relatively water poor granite magmas may produce single alkali feldspar granite and lower temperature crystallization of relatively water rich magma may produce two feldspar granite.
Magma to granite process.
Once we have arrived we will begin the process of either a digital laser template or making an accurate pattern of the areas where the stone will be installed.
Granite is actually made up of several different minerals including feldspar and quartz.
At this point magma is ready for the runaway process that leads to eruption.
Granite is formed by the solidification of magma under the earth s surface.
Other articles where granitic magma is discussed.
To form granite magma must first cool underground.
Once that starts the pace of activity in a magma rises dramatically.
This is an extremely slow process.

The final phase of differentiation involves the volatiles.
The water and gases that are dissolved in magma eventually start to bubble out as the magma rises nearer to the surface.
Mon 9am to 5pm.
Since the time required to form granite is rather long it is both a strong and valuable stone.
This process can take 1 3 hours.
If magma reaches the earth s surface and then solidifies it forms extrusive or volcanic igneous rock such as rhyolite or basalt.
During the process of fractional crystallization melts become enriched in incompatible elements.
