|The Dolomiti (also said Mounts pales) is a montain group of the Alps orients them, in Italy, conventionally delimited to north from the Rienza and from the Val Pusteria, to the west dall'Isarco and l'Adige with it goes it them same to south from the Brenta from which the Chain of the Lagorai to the border with the Val di Fiemme and to east from the Piave and the Cadore is detached. The Dolomiti d'Oltrepiave, situated to east of the Piave river, in the province of Belluno, Udine and Pordenone (and also in dell'Austria part, in Carinzia lowland), of the Dolomiti di Brenta, placed in the western Trentino, of the Dolomiti Small, between Trentino and Veneto, evidences the pure conventional nature of this territorial marking out. Dolomitic area extends between the province of Belluno - than of it it constitutes the more important part - Bolzano, Trento, Udine and Pordenone. The Dolomiti takes the name from the French naturalist DieudonnÚ Dolomieu (1750-1801) that for first carbonate of soccer and magnesium double studied the particular type of predominant cliff in the region (). The genesis of this type of carbonatica cliff begins through l'accumulo of calcareee shells, corals and alghe in marine and tropical atmosphere (similar all'attuale coralline barrier of the Bahamas, and dell'Australia it orients them). In particular, these accumulate had place in the Triassico, approximately 250 million years ago (remember that the Homo kind appears 3 million years ago), in zones with various latitude and longitude much dall'attuale lease of the Dolomiti, where warm and little deep seas existed. On the bottom of the seas hundreds of meters of sediment were accumulateed that transformed under their same weight losing the fluid insides and becoming cliff. Subsequently, the crash between the European plate and the plate African (orogenesi alpine) it made to emerge these cliffs raising them beyond 3000 m over the sea level. The landscape puts into effect them, spigoloso and rich of unevennesses, it appears to the eye of the tourist like a disordinato cliff crucible that null it has to that to make with the coralline barriers. To determine such transformation they have been: the foldings and the breaches of cliffs long sliding plans (faglie), to whose movements correspond as many earthquakes; episodic outbreaks vulcaniche and relati to you I placed to you; erosions differentiate tied them to the atmospheric agents and the plans of weakness inborn in cliffs. L'innalzamento of dolomitiche cliffs is tutt' hour in course. Today the Dolomiti shows the whiteness of the charges of coal of coralline reef, l'acutezza of cliffs been involved in recent orogenesi, the recordings of powerful exogenous agents (ghiacciai, wind, rain, cold-warmth...). At least six natural parks proteggono this particular nature and varies ad hoc comita to you is engages in proposing the Dolomiti to you like patrimony dell'umanitÓ. In the geologic future the Dolomiti will continue to grow taking new cliff fields pushed out from the crash between the plates European and African (like for the himalayana chain); the passing of this push will determine prevailing of the tending exogenous agents to level and to sweeten the landscape they mount (as it happens in the Urali). Some between the present known localities of holiday more in the dolomitic valleys are: Rocca Pietore to the feet of the Marmolada (in the Veneta part), Alleghe in the Val Cordevole, Falcade in Goes them of the Biois, Curtain d'Ampezzo in the Conca Ampezzana, Ortisei in the Val Gardena, Canazei in the Val di Fassa, Cavalese in the Val di Fiemme, Saint Martino di Castrozza in the Primiero, Arabba in Goes them of Livinallongo. Various pastures in high quota are present also, as as an example l'Alpe of Siusi or the Ampezzani Plateaus. Until 1800 m (depositors north) or 2200 m (depositors sun) the vegetation to you are mainly formed from coniferous forests (red fir, fir white man and silvestre pine), in the high quotas from forests of cirmolo and mughi. The tops higher are the Marmolada, with 3343 m. |
