The Blue Mountains ( French : Montagnes Bleues , Tuareg : Izouzadene or Izouzaoenehe ) are up to 921 m high foothills of the Aïr in Niger , which is about 30 km east-northeast of the town of Iférouane .
geography
The Blue Mountains are located on the eastern edge of the Aïr high mountains in the Ténéré desert . Administratively, they belong to the Iférouane department and are part of the UNESCO World Heritage Aïr and Ténéré nature reserve . They are also located in an Addax reserve.
The characteristic Cipollino blocks of the Blue Mountains were created from marine limestone under high pressure and high temperatures . Their bluish shimmer against the orange desert sand gave the mountains its name. The shimmer is caused by shares of different minerals, including mica and serpentine , as well as by a refraction of the light in the crystalline structure of the rock and a selective reflection of the blue light component.
