Informations supplémentaires

The geological sequence in the cliffs at Ajuy, Fuerteventura, Canary Islands, is unique and scientifically very important. The cliff sequence exposes Cretaceous oceanic sediments which represent the oldest rocks in the Canary Islands, many millions of years older than the volcanic amd associated rocks that form most of the islands. The sediments were formed very deep on the ocean floor and were uplifted many millions of years after they were deposited by the volcanic processes that formed the island of Fuerteventura itself. The overlying rocks are calcareous sediments formed from the remains of hard organic material that have solidifed to form a type of limestone and volcanic rocks erupted as the island evolved to its present state.
