Geology of Tenerife

The Anaga Massif, on the north-eastern tip of the island, has an irregular profile and rugged topography with the height of 1024 meters above sea level and through erosion over the centuries there is deep erosion and a dense network of dykes that cross the mountains. Rock types that appear on the surface are both trachyte and phonolite etiology.

There are many steep cliffs rising vertically on the coast of Anaga so there are a limited number of beaches and some coincide with areas of cave mouths, ravines, rocks and some have black sand.

Macizo de Teno – Zone Cliffs of the Giants
The Teno massif is located in the northwest and is an area of deep ravines and dismantled structures caused by erosion. However, the materials here are older over 7 million years old and The Mountain Gala is over 1300 meters in its highest altitude. The unique landscape of this massif is on the south coast.

These are the cliffs of Los Gigantes, with vertical walls that reach certain points that are 500 meters in height.

Massif de Adeje is situated at the southern tip of the island, with the highest peak is Roque del Conde, with an altitude of 1001 meters. The massif is not as prominent as the others as severe erosion has dismantled the peaks thereby losing their original appearance and size.

Dorsal

Cordillera dorsal or dorsal Pedro Gil runs from the top of Mount Hope, about 750 meters to the centre of the island, in the vicinity of the Las Canadas Caldera, where Izana is the highest being 2350 meters above sea level. This structure formed from a fissure-type basaltic volcaniv fault developed through one of the axles or structural guidelines that have given rise to the volcanic island.

The crest of Abeque is formed by a chain of volcanoes that link Teno Massif Central Island with the Teide-Pico Viejo on the Tenerife fault kines. The volcano dorsal of Chinyero last historical eruption was in 1909.

The dorsal Sur Adeje is under the last of the structural axes fault lines and the remains of its original formation alignment of small volcanic cones and rocks scattered throughout this area of southern Tenerife.

Valleys
The overview of the Orotava Valley with Teide in the background are another prominent relief with the most important being the Orotava Valley and the Valley of Guimaras created from scree  generated by a landslide of large quantities of loose material falling into the sea creating a hollow in the ground.

There are other valleys that are distributed across various locations in the geography of Tenerife, but in this case, of a different nature. Usually intercolinares, valleys formed after the deposition of materials in lateral ridges, channels or gullies that take on the appearance of typical valleys.

Barrancos

Tenerife, mainly due to its high altitude and its similarity in shape to a roof has large amounts of water runoff and is surrounded by a large number of gullies. They are one of the most characteristic elements of the landscape, caused by erosion exerted by surface water runoff through thousands of years

There are many notable ravines Ruiz, Fasnia and Guimaras, and Erques Hell and some are declared natural areas like Montana Roja, Playa La Tejita. South Zone. Playa del Bollullo coast of Orotava. Zona Norte.

Costas

The costs are usually rugged and steep, but they are more in the north than in the south. Nevertheless 67 miles from the coast of Tenerife are the beaches only surpassed in this by the island beaches of Fuerteventura. In the northern coast are pebble beaches of black sand, while the southern slopes and southwest of the island dominated by fine sandy beaches and clear colours.
