It is also known as CaMg (CO 3) 2 and is a type of compact limestone consisting of a calcium magnesium carbonate. In combination with calcite and aragonite, dolomite makes up approximately 2% of the earth's crust.

On a dolomite matrix we can enjoy several pyrrhotite crystals, hexagonal, with luster, many of them isolated and others interpenetrated.

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 similar ...

Dolomite is a calcium magnesium carbonate mineral which has many characteristics similar to calcite. In places where access to limestone is not available or more costly, dolomites are used in its place for the basic materials from which most building stone and a significant percentage of crushed stone are produced.Some calcite specimens contain euhedral crystals, but many are rhombohedral cleavage fragments like those in Figures 14.361 and 14.362. The photo in Figure 14.361 shows calcite with its most common whitish color. The photo in Figure 14.362 shows (less common) blue calcite cleavage fragments. Other colors too, are possible.
