Almeria geological evolution
Any landscape at any region of the world is always changing and changable; under this point of view the mountains and valleys around us are not always at the same position than millions (or thousands) of years ago. In most cases the land on which we step on, was formed underneath an old sea that emerged to the surface due to the so called plates tectonic; this land changes are due to complex geological and global processes, and they are printed on the rocks that can be found when we visit these areas, as for example the valleys of Alfaix, Macael, Sorbas or Tabernas.
Geodiversity is huge in the Almeria region: volcanic materials, metamorphic rocks, evaporitic and sedimentary layers… we need few more materials to read and understand a big part of Earth´s story, experienced under the framework of a unique landscape in the most arid place of Europe and one of the most dry places in the World. The fossil and geological register is tremendously big here, talking us about the most recent times of what we know nowadays as Andalucia region (southernmost 8 provinces in Spain) and also helping us to understand the geological formations along all the Mediterranean basin, mainly on the las 15 millions of years. In Almeria´s landscape there can be recognized easily two different land formations: the sierras (ranges of mountains) and the depresiones (flatlands emerged from the sea and afterwards eroded by the effect of the ramblas (dry beds of seasonal rivers, usually responsible of generating flash floods).
Our highest peaks are located in the sierras known as Sierra Nevada, Sierra de Filabres, Sierra de Gádor, Sierra de Alhamilla and Sierra de Cabrera; they are part of the so called Baetic Massif (Macizo Bético); the rocks there are mainly mica-schist, slate, quartz, limestone and marble… that were originated from deposits of any sea happening very faraway, hundreds of millions of years ago (perhaps more than 500.000.000). Later these huge masses of land were moved slowly adrift to their actual positions and lifted up by the collision of the two huge continents named actually as Europe and Africa, in the process named Alpine Orogeny, global process that could be started 60 millions of years ago and that is still happening.
Almeria is no doubt, one of the top 10 places to visit in your life. Come and see… That was only an aperitif to Almeria geological evolution.
