The Dolomites, also known as the "Pale Mountains", take their name from the carbonate rock dolomite. This was named for 18th-century French mineralogist Déodat Gratet de Dolomieu(1750–1801), who was the first to describe the mineral.
The Dolomites are a mountain range located in northeastern Italy. They form a part of theSouthern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley. The Dolomites are nearly equally shared between the provinces of Belluno, South Tyrol and Trentino.
