· Dolomite is hexagonal (rhombohedral), a = 4.84, c = 15.96, Z = 3; space group R3; point group 3. Habit Dolomite forms rhombohedral crystals, having the shape of cleavage fragments, often with curved faces. Less commonly they are prismatic or steep rhombohedra. Lamellar twinning is nearly always present but may be hard to see.

The Dolomite Group is composed of minerals with an unusual trigonal bar 3 symmetry. The general formula of this group is AB (CO3)2, where A can be either calcium, barium and/or strontium and the B can be either iron, …

 · Mineral Group: Dolomite Group. Content . Description People often ask General Info. Description . Dolomite, also known as Dolostone, is not to be confused with the mineral of the same name; it is merely a sedimentary carbonate rock that contains this mineral. It is said to resemble limestone and was not distinguished from the former until 1778.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. Dolomite is referred to as magnesian limestone. Its colour range varies between colourless to white, pale brown, greyish, reddish, or pink mineral. Dolomite is found in hydrothermal veins associated with lead, zinc, and ...

Dolomite. Dolomite is the name of a carbonate rock consisting of the mineral dolomite. This type of rock is closely related to limestone. It is formed by limestone being exposed to a process called dolomitisation, which, in brief, involves some calcium ions being replaced by magnesium ions. The chemical formula becomes CaMg (CO 3) 2.

Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. The bulk of the dolomite constitutes dolostone formations that occur as thick units of great areal extent in many …
