Dolomite rock is defined as sedimentary carbonate rock composed of more than 50% mineral dolomite. Dolomite is characterized by its nearly ideal 1:1 stoichiometric ratio of magnesium to calcium. It is distinct from high-magnesium limestone in that the magnesium and calcium form ordered layers within the individual dolomite mineral grains, rather than being arranged at random, as they are in high-magnesium calcite grains. In natural dolomite, magnesium is typically betwe

Dolomite is even used in facial creams and toothpaste. Usually minerals are named after a famous geographic locality where they occur, but dolomite was named for a French geologist named Deodat de Dolomieu (1750-1801) who first identified its chemical composition, and whose scientific career had a rather inauspicious beginning.
