Limestone where dolomite is present in more than a small amount are called dolomitic limestone. Dolomite is only rarely found in higher temperature metamorphic surroundings. Except in its pink, curved crystal habit dolomite is hard to distinguish from its second cousin, calcite.
Dolomite is formed through a process called "dolomitization," where lime mud and limestone are altered by magnesiumrich groundwater, converting calcium into magnesium.
