Sistema Ibérico

The Iberian Mountains (Spanish Sistema Ibérico ) is a mountain system in Spain. It forms the eastern edge of the high central tableland and also the main watershed of the Iberian peninsula between the Atlantic Ocean and the Mediterranean Sea.

The Iberian mountain range stretches, unlike the other mountain systems, from northwest to southeast. It consists partly of mountain chains and mountain ranges, some of interposed therebetween plateaus and Parameras. It spreads from the Ebro sources beginning, to the south significantly from. Here cover its ramifications throughout the broad and terraced eastern and southern slopes of the plateau. They come right up to the coasts, which they gird in further expansion of the mouth of the Llobregat to up against the back of the Segura. The mountain system covers the east of Castile, very Valencia, Südaragonien and southern Catalonia ( probably in the whole 40,000 square kilometers). It describes a with its convexity swept to the northeast arc of 650 kilometers in length.

Structure

The Iberian Mountains can be naturally separate into three sections:

Altkastilische chain

The altkastilische chain on the right bank of the Ebro is composed of the Sierra de la Demanda ( 2,305 m), the group of Pico de Urbion ( 2252 m), the Cebollera ( 2176 m) and the Sierra de Moncayo ( 2314 m).

Südaragonisches Highlands

The südaragonische upland stands south of Jalon as a continuation of the altkastilischen chain and consists of the Sierra de Cucalón and other illegal southeast trains. At the sources of the Guadalaviar and Alfambra it widens to a widely branched Bergland. This reaches from the Aragonese province of Teruel over in the adjacent province of Cuenca, where it forms the Serranía de Cuenca, and in the Valencian province of Castellón, where it is to abdacht against the sea. To the north it extends to the Ebromündung; beyond it finds it in the Catalan mountain road its continuation.

Excellent mountain ranges in this part of the Iberian mountain system of the Sierra de Albarracin, the Sierra de Gudar (1770 m), the Sierra de Javalambre (2002 m) and the group of Peña Golosa (1813 m). The südaragonische highlands appears to be an extended plateau, which is furrowed by valleys on all sides of the abgießenden waters. Rugged, jagged rocky mountains with deep gorges, however, form the eastern, the Castellón province fulfilled branches.

Südvalencianisches Bergland

The südvalencianische Bergland is located between the lower reaches of the Guadalaviar and Segura. It is separated from the Júcar into two parts, each consisting of a set of parallel, slightly or not contiguous, divorced by wide valleys mountain walls. These include the Sierra Martes, the Sierra Enguera, the Sierra Groza and the Sierra de las Cabre. They run back towards the coast and end in many rugged rocks cape. The most important elevation is here the Moncabrer ( 1386 m).

Geology

The Iberian mountains usually seems to belong to the Jurassic or even from older Tertiary formations ( nummulite ) to exist. Marble and sandstone are common. The larger valleys contain tertiary storage. It is characteristic of the middle part of the whole train the shape of the Parameras and for the southern part of the Muelas ( " millstone "), ie isolated, abgestutzter and rugged sloping rock cones.
