Le origini e il futuro delle dolomitiThe Dolomites are named after the French naturalist Déodat de Dolomieu (1750-1801) who first studied the particular rock type predominates in the region, named in his honor dolomite, primarily composed of the mineral dolomite (MgCa (CO3) 2) or double carbonate calcium and magnesium.
The genesis of this type of carbonate rock begins by accumulations of shells, corals and calcareous algae and in marine and tropical (similar to today’s coral reefs of the Bahamas, Australia and Eastern Europe), which took place in the Triassic period, about 250 million years ago, in areas with latitude and longitude very different from the current location of the Dolomites, where there were warm, shallow seas. At the bottom of these seas piled hundreds of feet of sediment that, under their own weight and losing the internal fluids, turned into rock. Subsequently, the clash between the European plate and the African plate (Alpine orogeny) brought out these rocks rise above 3000 m above sea level.
The current landscape is edgy and full of gradients. To determine this transformation have been bent and broken rocks along slip planes (faults), whose movements are so many earthquakes; episodic volcanic explosions and related deposits; differential erosion related to atmospheric agents and plans to inherent weakness in the rocks.
The rise of the dolomite rocks is still in progress. Today the Dolomites show the whiteness of the carbonate reef, the sharpness of the rocks involved in recent orogeny, engravings of powerful exogenous agents (glaciers, wind, rain, cold-hot).
In the future, geological, the Dolomites continue to incorporate new areas of rocks driven by the clash between the European and African plates (similar to what happens to the Himalayas); the disappearance of this thrust will determine the prevalence of exogenous agents tend to smooth and soften the mountain (as has happened in the Urals).
