How is Blue Granite Made
Blue granite is not common among all types of granite
The most famous types of “granite” in blue are not granites but quartzites, namely the world-famous blue natural stones such as the Ankara smoked and the Aksaray Sipahi. The number of individual blue granite types is manageable. This beautiful rock is weather-resistant and frost-resistant. Properties that are usually attributed to almost every granite. Because of this, it is versatile to use outdoors as well as indoors.
The blue granite from Europe
One of the few blue granites that are mined in Europe is the Kseine granite or Schurbach granite. Its occurrence can be found not far from the Kössine massif in Upper Franconia. This is a two-mica granite or biotite muscovite granite. But where does the Kseine granite get its blue color, which is basically very unusual for a granite? The cordierite deposits are responsible for this. Cordierite has also been referred to as dichroic in the past. It is a mineral of silicates and germanates. From a chemical point of view, it is a magnesium aluminum silicate. This granite is the only granite mined in Europe that also deserves the name “blue”. All other granites tend to have a bluish, gray-blue or light blue color.
