Dolomitic limestone has both calcium carbonate and magnesium carbonate while regular limestone is just calcium carbonate. According to my very old handbook (from my U of Guelph days in the last century) it takes 86 pounds of dolomitic limestone to equal 100 pounds of regular limestone in correcting acidity. Typically, dolomitic limestone is used when there is a need for magnesium.
Dolomite is a rock consisting mainly of calcium and magnesium carbonate. It was named for D.G. de Dolomieu, a French geologist (1750-1801).
