From Wikipedia:
The Iberian System (Spanish: Sistema Ibérico), is one of the major systems of mountain ranges in Spain. It consists of a vast and complex area of mostly relatively high and rugged mountain chains and massifs located in the central region of the Iberian Peninsula, but reaching almost the Mediterranean coast in the Valencian Community in the east.
From the hydrographic viewpoint this system is of the highest relevance in the peninsula, for it separates the watersheds of most of the major rivers in Spain and Portugal, including the Ebro basin from the basins of the Douro, Tagus, Guadiana (Záncara-Gigüela), Júcar and Turia.
There are important mining areas in some of the ranges such as Sierra Menera, Sierra de Arcos and Sierra de San Just, making the system one of the chief mining regions in Spain since ancient times.[1][2] One of the comarcas of Aragon located in the Iberian System was given the name of Cuencas Mineras since mining is the main activity in the comarca.
Location and description
The Sistema Ibérico mountain range borders the Meseta Central on its western end and separates the Meseta Central from the Ebro valley and from the Mediterranean coast.
This system runs northwest-southeast between the Ebro plain and the Meseta Central for over 500 km, from the La Bureba corridor in Burgos Province close to the Cordillera Cantábrica to the Mediterranean sea close to Valencia in the south and close to Tortosa and the Ebro Delta in the east. The bulk of the Sistema Ibérico is located in the southern half of Aragon. The Prebaetic System rises south of the southernmost end of the Iberian System.
The geology of the Iberian System is complex, for it can hardly be defined as a homogeneous system. It is composed of a haphazard and motley series of mountain ranges, massifs, plateaus and depressions without a definite common petrologic composition and overall structure. Nummulite limestone, marble and sandstone are common throughout the area. Some of the parts of the system stand geologically isolated, interrupting the continuity of the whole, linked to the other parts through high plateaus of varying altitudes.
