What Minerals Does Granite Contain?

Orthoclase and plagioclase feldspars, quartz, hornblende, muscovite micas, biotite micas, minor accessory minerals such as magnetite, garnet, zircon and apatite go on to make up the mineral composition of granite. Sometimes, though rarely, pyroxene is also present.
The word granite is derived from the Latin granum meaning a grain, which is because of its coarse grain structure. In order to qualify as true granite, samples now must contain plagioclase and orthoclase feldspars. Granite is important due its toughness, and since it is always found in huge formations, it is very much appreciated by architects, engineers and anybody else related to the construction industry.

Granite can be dark grey, black or pink in color, and even though it is distributed evenly throughout the earths crust (unlike oil and gas), there are large deposits or concentrations in Scandinavia, Spain, Brazil, India and in the southern parts of the "Dark Continent", in Angola, Zimbabwe and South Africa.

Its use to man is not new; he has used it to pray to his Gods whether in Greece, Egypt or India.
