Approach to the geology of Aragn. The Geologic Patrimony Aragones. Nature in Aragon. Aragon



The geologic rqueza of Aragn is impressive:
Old glaciers, torrid solariums, steep reliefs, ample plains, always blue lakes, desert steppes, leafy forests, feracious fertile valleys...

All this and much more can be in the landscaping mosaic that forms Aragonese earth, from the heights superior to the 3,000 meters in the Pyrenean one to the 150 meters on the level of the sea in which is the bed of the Ebro.

Near 50,000 Km2 of extension of this community, 9.4 % of the one of Spain, region is formed by three great geologic dominions: the Pyrenees, the depression of the Ebro with the somontanos Iberian Pirenaico and and the Iberian mountain range, that lodge, in addition to the great spaces to consider, manifold points more reduced in extension, but not for that reason deserving of neglect or ignorance.

The Pyrenees, to the north

The Pyrenees are already of in case, as a whole, a true natural museum.
It has a great variety of litografias, whose older ages go back to the Precmbrico (we can be located around the 600 million years), are structured of complex form, like result of the approach between the plates Iberian and European.
That process, whose last phases had to culminate about 20 million ago years, has left its sequels, in form of a certain growth of the reliefs that still remain, of a moderate sismica activity and a termalismo of which we have good model in the Baths of Panticosa. In the other end, in the valley of Benasque, the Forau de Aigualluts is a splendid krstica example of torca, that devours a mighty torrent.

The Pirenaica mountain range, aligned of this a the west, extends from the Mediterranean to the Cantabrico. The central part, exactly steepest, corresponds to the most northern part of Aragn, to a large extent to the province of Huesca.

Of north to the south, the Aragonese Pyrenees or Pyrenean power stations present/display three parallel geographic units:

The river basin of the Ebro; the paper of the Ebro river.

The river basin of the Ebro, valley and somontanos, begins to form makes about 60 million years, during orogenia alpine, giving rise to a vast extension, true geographic depression. Their edges are formed by detrticos materials coming from the mountain ranges and its central part by yesferos and evaporticos materials produced when drying up the inner sea that makes million years was the valley.

It contains many remarkable geologic elements: the salty ones of Alcaz and Sstago-Bujaraloz, the steppes of Eastern Belchite or the Bardenas, the exhumados paleocanales of Alcaiz or Caspe, the mines of Eddy salt or the Mallos de Riglos are some examples to mention.

The valley

The central zone of Aragon occupies the valley of the Ebro and the somontanos of the Pyrenean one and the Iberian. Great part of Zaragoza and Huesca and the Low turolense Aragn is regions that watch the Ebro.

The main body of this geographic unit is the ample valley formed by the terraces of the Ebro and, sometimes like in the city of Zaragoza, other affluent rivers. On these terraces, the runner of the Ebro, lives more than half on the Aragoneses. Thanks to regadio are rich earth and to the underground water availability and around the city of Zaragoza, political and economic capital of Aragn, to industries and services that they attract not only the ribereos towns, but to all the people of Aragn have risen.

To the north and the south of the valley of the Ebro small platforms like Alcubierre rise (822 ms), the Tooth (627 ms) and Mounts of Castejon (744 ms). Of these "teeth" they take extensive piedemontes sectioned by a sporadic network of drainage. That network, times forms valleys in flat bottom (bonds) and others, strongly gotten stuck valleys that make arise yesferos or saline lands. They are landscapes of extreme dryness, not only by the little thing of precipitations, but also by the influence of the wind and the litologa of the land. In Monegros, Bardenas or Calanda appears the Aragonese desert.

The Iberian Mountain range.

The Iberian mountain range, that occupies almost all the province of Teruel and the western margin of the one of Zaragoza, is another great sample book of geologic wealth. It is formed in next periods in the time (the geologic time), although noncoincident, to the Pyrenees.

Teruel has been well-known by its intense mining activity in relation, mainly, with the coal (the Val de Ario is a very representative zone) and, until for years, with the iron mineral (Black Eyes). Mineria of clays, also important, finds a good exponent in Galbe, whose term constitutes in addition a valuable deposit to rest of dinosaurios. Another paleontological deposit good known between the collectors is the one of fossils of Book frogs.

Poljes of the turolense southern strip, the dolinas and other geomorfolgicos enchantments of the mountain range of Albarracin, the magical Crystal Grotto of Mills or the surgencias of the birth of the Pitarque river are good sample of which the action of the water is able on limestones.

The periglaciales forms in the mountainous bulks of Gdar, Javalambre and Albarracn are also showy, and quizas, among them, most outstanding are the peat bogs and stone rivers of the mountain range of the Tremendal.

The vertical layers of the Organos de Montoro, the extensive endorreica lagoon of Gallocanta, the travertinos and tubes of the rivers Table and Stone, the termalismo of Alhama de Aragn and Jaraba, the alluvial fans of Palomera mountain range ... are so single some cases more of the ample repertoire available.

Also Aragon enjoys a diverse and varied Nature where passing by plants, animals, Geology, or landscapes we can arrive at a fantastic bestiary that lives in its monuments.

The information will not be complete without a stroll by its three provinces, with shutdown in some of its spectacular landscapes like Ordesa, the Moncayo, Monegros or by opposition the Ebro.

Also you can dedicarte to the intangible ones: from the legend compilation that also does to universal Aragon.

The pasapues project is an extension of the Aragón project is like that, and tries to collect and relate all possible types of documentary information about Aragon: texts, books, articles, maps, illustrations, photographs, narrations, etc., and proceed to its publication and diffusion.
