Sierra de la Fausilla

[2] This protected area is located in the western sector of the Sierra minera de Cartagena-La Unión, a mountain range that constitutes one of the last foothills of the Baetic System, formed in the Tertiary period, during the so-called Alpine orogeny, due to the collision of the European and African plate tectonics.

[3] This area of the Sierra Minera forms part of the so-called Alpujarra complex, made up mainly of metamorphic and sedimentary rocks, mainly limestone.

The Sierra de la Fausilla has already experienced serious deterioration of its environment with the clearing of an enormous portion of land in the Aguilones rock for the construction of the Escombreras super-port.

Currently, its eastern sector is also under threat, with the project to build a large container terminal in the cove of Gorguel.

[6] On 15 March 2013, a fire broke out on its northern slope from 10:56 am to 8 pm (declared extinguished the following day), affecting approximately 50 hectares starting from the vicinity of the new REPSOL refinery.
