The formation of granite.
Of these minerals feldspar predominates and quartz usually accounts for more than 10 percent.
There are a variety of granite uses and the granite reserves are found in many countries around the world.
Granite crystallizes from silica rich magmas that are miles deep in earth s crust.
Granite formation took place millions of years ago.
This is an extremely slow process.
Granite is more common in continental crust than in oceanic crust and has a felsic composition.
Granite is formed by the solidification of magma under the earth s surface.
Each rock has a unique formation process.
The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks.
The alkali feldspars are often pink resulting in the pink granite often used as a decorative stone.
To form granite magma must first cool underground.
They are crystallized by felsic melts that are less dense than mafia rocks and therefore tend to ascend to the surface.
Granitic magma must make room for itself or be intruded into other rocks in order to form an intrusion and several mechanisms have been proposed to explain how large batholiths have been emplaced.
