The Dolomite Problem | Discover Magazine

The Dolomite Mountains, Italy's Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesium--and through the action, McKenzie suspects, of sulfate-reducing bacteria.
