Sierra Morena
From Biocrawler, the free encyclopedia.
The Sierra Morena is a mountain chain some 400 km long running East-West in southern Spain, forming the border of the central plateau (Meseta Central) of Iberia, and providing the watershed between the valleys of the Gaudiana to the north and the Guadalquivir to the south. It has valuable deposits of lead, silver, mercury, and other metals, some of which have been exploited since prehistoric times.
The Sierra Morena is the result of uplift produced by the pressure of the northward-moving African Plate.
much of its natural beauty is now protected in National Parks, such as Despeñaperros, Sierra de Andújar (Jaén), Sierra de Cardeña-Montoro, Sierra de Hornachuelos, Sierra Norte de Sevilla and Sierra de Aracena Huelva.
