GRANITES

Classic and the best cust of the market, granite is a common type of felsic intrusive igneous stone that is granular and phaneritic in texture. It 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 stone. Strictly speaking, granite is an igneous rock with between 20% and 60% quartz by volume, and at least 35% of the total feldspar consisting of alkali feldspar, although commonly the term “granite” is used to refer to a wider range of coarse-grained igneous rocks containing quartz and feldspar.
