The pink granite coast in Brittany: an exceptional site
This geological feature extends over 10 km in het northwest of the French department of Côtes d’Armor.
In addition to its characteristic colour, the “Côte de granit rose” is dotted with chaotic clusters, the flagship of which is the customs path (Sentier des douaniers).
There are only 3 pink granite coasts in the world, one in Brittany, one in Corsica and one in China.
Why pink?
The granite is made up of 3 main minerals: mica that gives it its black colour, feldspar which gives it its pink colour and quartz which gives a grey tint.
Feldspar is usually white, except that on this coast hematite impurities have been added to the crystal lattice of feldspar.
