Dolomite is a calcium magnesium carbonate. It is the primary component of the sedimentary rock known as dolostone along with the metamorphic rock dolomitic marble. Dolomite is found in sedimentary basins worldwide and it is thought to form by the post depositional alteration. Dolomite has a unique saddle-shaped crystal growth pattern, made up of calcium magnesium carbonate and most likely exists in sedimentary or metamorphic rocks.
