Dolomite Mineral | Uses and Properties

What is Dolomite? Dolomite is a common rock-forming mineral.It is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2.It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble.Limestone that contains some dolomite is known as dolomitic limestone.

Dolomite vs Quartzite - rocksparenature

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone.

Sedimentary rock - Limestones and dolomites | Britannica

Sedimentary rock - Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2).
