Dolomite: Dolomite mineral information and data.

Dolomite and ferroan dolomite occur frequently as pseudomorphs after calcite and also after aragonite. Rarely pseudomorphic after cerussite, baryte and fluorite. Several species have been recognized as incrustation or substitution pseudomorphs after dolomite …

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.

Dolomite: The Mineral Dolomite

Dolomite is a very common mineral and is best known for its saddleshaped curved crystal aggregates. A unique, isolated Dolomite occurrence in Eugui, Spain has provided colorless transparent crystals that resemble the Iceland Spar variety of Calcite, and have no resemblance to Dolomite specimens from any other localities.

Dolomite | GeoKansas

The mineral dolomite is the main component of the sedimentary rock that is also called dolomite. It is similar to the mineral calcite but contains magnesium as well as calcium. Just based on looks, the rock dolomite is often impossible to distinguish from limestone , which is composed mainly of calcite.

Dolomite is very similar to limestone, and they are difficult to tell apart based only on appearance. The difference between the two is that limestone is composed mainly of the mineral calcite (made up of a combination of calcium, carbon, and oxygen) and dolomite is composed mainly of a mineral that is also called dolomite , which is like ...

Dolomite

As an industrial mineral, dolomite’s usage is significantly less than calcite’s. This is primarily due to the relative lack of high brightness deposits of dolomite. The alteration process that forms dolomite tends to bring in additional impurities that reduce brightness or tint the stone brown or gray.
