Dolomita (português brasileiro) ou dolomite (português europeu) [6] é um mineral anidro de carbonato de cálcio e magnésio, com fórmula ideal CaMg(CO 3) 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.

For 200 years, scientists have failed to explain how the mineral dolomite could form in such large quantities to shape entire landscapes. Now, researchers have finally succeeded, thanks to a new ...

Dolomite is a sedimentary rock made mostly from the mineral dolomite and it's also known as dolostone. Sometimes, showrooms will label Dolomite as "hard marble," and the reason for this is because it is denser than marble. Dolomite is porous, though not as susceptible to staining, etching and cracking as marble.

Dolomite is a rock-forming mineral that is the primary mineral in a range of stones, such as Dolomitic Marble and Dolostone.

Dolomite is a mineral and a rock-forming mineral that is composed of calcium magnesium carbonate (CaMg(CO3)2). It is named after the French mineralogist Déodat Gratet de Dolomieu, who first described its properties in the late 18th century. Dolomite is often found in sedimentary rock formations and can occur in a variety of colors, ranging from white …

Dolomite lime is a type of lime containing both calcium carbonate and magnesium carbonate. It comes from underground limestone deposits, which appear as white, tan, gray, or pink crystals. Dolomite lime is used to raise soil pH, and it adds both calcium and magnesium to soil.
