Granite - Types and properties
Types and properties of granite
Granite is a coarse-grained type of intrusive igneous stone (composed mostly of quartz, plagioclase and alkali feldspar).
A magma formation with a high content of silica and alkali metal oxides that slowly drops its temperature and solidifies underground. Granitic rocks family contains various closely chemically related natural stones (composed of coarse-grained quartz and feldspars in varying proportions) with the most famous being granite.
Classified by the relative percentages of quartz, alkali feldspar, and plagioclase (QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain amphibole and mica minerals.
In general Granite is a durable and strong building material due to its high density. Granite is mostly used in vanity tops for its superior quality characteristics and well as its unique aesthetics. Finally, granite is also used in the foundations of the facilities.
