Dolomita ( português brasileiro) ou dolomite ( português europeu)[ 6] é um mineral anidro de carbonato de cálcio e magnésio, com fórmula ideal CaMg (CO3)2, muito abundante na natureza sob a forma de rochas sedimentares dolomíticas. Este mineral é utilizado como fonte de magnésio e, sobretudo, para a fabricação de materiais refratários .

Dolomite, also known as " dolostone " and " dolomite rock ," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very

· The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder

· Dolomite is a harder-than-average material and is not as fragile as marble. On the Mohs hardness scale, dolomite rates at 3.5 – 4, superior to marble’s Mohs rating. A higher hardness rating makes it a durable and strong countertop over time, capable of supporting various uses while being resistant to wear and tear.
