Almeria landscape volcanism
A unique place in Almeria landscape and totally different of others is the Cabo de Gata Sierra (Range of mountains of Gata Cape). Its geological origin is mainly volvanic, and much more younger than other territories in the actual almerian geography. Its age has been estimated by scientists in approximately 14 to 7 millions of years ago.
Indeed the area of Gata Cape (Cabo de Gata) is only a small emerged portion of a wide submerged (under the sea) area underneath the so-named Mar de Alboran (Alboran Sea), between Africa and Europe continents.
Did you know that the tiny Alboran Island is a part of Almeria province?. Actually it is used only for science research and as a spanish advanced military position overseas.
This volcanic activity happened, at least partially, below the Sea level. It has been supposed that what happened was that the volcanoes finally emerged as islands, creating an authentic volcanic archipelago. Around these small volcanic islands, in the middle of warm subtropical sea waters, grew abundantly the corals (Anthozoa – Cnidaria), building coastal atolls and reefs, that still can be seen very clearly in some locations at the National/Natural Park.
Hydrothermal fluids would change later the volcanic rocks composition, so as sometimes happened in the nearby Baetic Mountains, mineralizing them and generating so unique and abundant metallic deposits.
To understand the actual Cabo de Gata landscape we need to understand two different concepts: one is the Plates Tectonic movement, that is responsible of the slow raising of the rocks, so that submerged lands are now totally offshore; the second concept is the dryness of the area in whichit rains very scarcely… but when it does happen, usually water come down from the sky generously in only a moment (some minutes or hours), generating the so usual flash-floods that are the responsible of a high level of erosion, also so important to read and understand the actual configuration of Cabo de Gata volcanic landscape.
The main rocks that can be found in the area are basalts/andesites , ignimbrites/bentonites and lots of conglomerates everywhere. Some metamorphic rocks (micaschist/quartz) also can be found in the ramblas (temporary bed of seasonal rivers) but these materials really have been not generated in this area… but moved along time from the faraway Filabres and Alhamilla mountains, dragged with the water of the mentioned flash-floods.
Gold, silver and lead among other minerals, have been mined in the area along times since the ancient Roman Empire era, so as basalt cobbles were quarried for being used in the past 20th Century for paving roads in Almeria town and other main villages nearby or faraway.

Did you know that in Cabo de Gata National Park there is a place baptized (by me) as The Dwarf Causeway?? Can you imagin the reason for that???
