Geological Formations: Plains, Valleys, and Mountain Ranges

Plains and the Ebro Valley

In the late primary period, along with Catalonia, a sea paneled. In the secondary period, there was much sedimentation. The Pyrenean stage lifted the edges, especially to the north (Pyrenees), which became a gulf, and a rise in the lake's eastern hills occurred in the Miocene epoch. In the Quaternary period, it emptied through a crack in the Mastership.

Levante Coastal Formations

Low cost of sea and river silting.

Guadalquivir Valley Formation

Similar to the Ebro Valley in form and unifying factors. The primary mountains rose in the secondary area, which was covered with water in the Betic tertiary period. The tilting of the peninsula emptied the area on the Gulf of Cadiz, where the contributions of the river converge, rivers and the Atlantic sea.

Peripheral Mountain Ranges (Peninsula)

Very high Pyrenees area. Rises in the primary axis of the range. In the secondary period, large amounts of sediment accumulated in the adjacent sea. In the Tertiary Alpine orogeny, the shaft closed and sedimented balloons mated. The stage brings salica max wheel height and cracking.

• P. Axial (basically glacier) - P. Gerona - P. Centrales and P. Orientales
• Groove Intrapirenaico: clear channel line d Berdum
• Prepirineo marks the division between the valley of the Ebro and the Pyrenees

Catalonia Mountains

Parallel to the coast, close to the Ebro Valley to the east, they are of height and Anxur pekeñas but important human and economically. The materials are crystalline and metamorphic rocks. The units are:

• Maresme
• Coastal mountain ranges pekeñas low-elevation
• Central dep-graben between two blokes lifted
• Cordi prelitoral-separates from the inner coastal Cataluña

Betic Sierras Formation

In the primary massif, the Betica-rifetin rises, separated from the Hesperian massif and Gondwana. In the secondary period, large quantities of material are deposited, which rise very quickly at the end of the Tertiary, resulting in very complicated ways to be soft materials. Units are:

• Sub-Betic Sierras: Cazorla
• Dep Penibética-filled area, rich soils: Guadix
• Sierra Penibética pricier higher elevation-axis: snowfall
• Intrapenibetico groove: Alpujarras
• Subpenibetica range coastal zone

Largest Basque Mountains

Population formation bit high cordi located between the coast and the Pirin, mat Mesozoic (limestone). Rounded by erosion.
