Dolomite Rock - Limestone Rock Type, Composition, Formation, Types & USES
The dolomite was composed of relatively poorly ordered proto-dolomite crystals with micron-sized spherical or sub-spherical morphology and coexisted with hydrothermal minerals, including analcime, buddingtonite, albite and chalcedony. Albite clasts were replaced by the dolomite, indicating high-temperature conditions during formation.Dolomite rock is a very common sedimentary rock, especially older carbonate rocks (formed before the Mesozoic) tend to be dolomites whereas younger carbonates are predominantly various limestones. What Colour is dolomite? Physical properties. Dolomite crystals are colourless, white, buff-coloured, pinkish, or bluish.

Dolomites (Chapter 10) - Dolomite Mineral | Uses and Properties
Dolomite rock textures can be classified according to crystal size distribution and crystal boundary shape. The classification scheme presented here is largely descriptive but carries genetic implications because size distribution is controlled by both nucleation and growth kinetics, and crystal boundary shape is controlled by growth kinetics.Dolomite, CaMg (CO3) 2 is a common component of many carbonate rocks and typically forms through the replacement of limestone. However, despite intensive study for more than 200 years, the origin of dolomites (or dolostones) is still subject to considerable controversy.
