Dolomite

Dolostone, or dolomite, or dolomitic rock, is a carbonate rock made up of the mineral dolomite - calcium-magnesium carbonate - that is secondarily derived from limestone. Although dolostones may be found in other places too, only these mountains are called the Dolomites, after the English naturalist who first identified the connection with the mineral dolomite, which a Swiss student, in turn, named after the French geologist Dolomieu.
