The same way there are many similarities between limestone and dolostone, there are also many differences. For one thing, limestone is a calcium carbonate material while dolomite is made of calcium magnesium carbonate. There are things found in limestone that are not found in dolostone such as clay, sand, and silt.

The Dolomites (Italian: Dolomiti [doloˈmiːti]),[1] also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders

Dolomite is a common rock-forming mineral. It is the primary constituent of dolomite rock ( dolostone) and dolomarble. It is similar to the most common carbonate mineral calcite. These two share some similarities in structure and are very closely related chemically. Calcite is chemically CaCO 3 (calcium carbonate), dolomite is CaMg (CO 3) 2

Marine limestone forms because seawater has high concentrations of two key dissolved chemicals-calcium (Ca ++) and bicarbonate (HCO 3-) ions. In the near-surface layer of most oceans, corals, clams, and other sea-dwelling creatures use these two chemicals to make protective shells by combining them to form calcite or "aragonite," which is the same

Dolomite is the name for a mineral composed of calcium magnesium carbonate (CaMg (CO 3) 2) and for a sedimentary rock that has this mineral as its chief constituent. The rock was given this name first, but to avoid confusion it is sometimes known as dolostone. The pure mineral is white, but traces of impurities can give it a range of colors

Simply put, Dolomitic Limestone is just a variant of Limestone (a sedimentary rock), consisting of mainly magnesium calcium carbonate instead of calcite and aragonite. Dolomitic Limestone is also known as “Dolomite,” and is often preferred over Limestone because it has a harder composition, is less absorbent and more resistant to freeze-thaw

By volume, however, most dolomite occurs in its massive form as dolostone or mixed dolostone/limestone sedimentary rocks. These dolostone rocks originally formed as limestone marine deposits on ancient shallow seafloors that were later altered to dolostone as magnesium-rich waters moved through them.
