Dolomite Facts Softschools

Dolomite Facts. Dolomite is a mineral and a rock that has a unique saddle-shaped crystal. It is made up of calcium magnesium carbonate and most likely exists in sedimentary or metamorphic rocks. Dolomite is commonly found in many European areas, Canada, and Africa. Interesting Dolomite Facts: Dolomite is used to make the medicine application

Classification of dolomite rock textures Journal of

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: A sedimentary rock known as dolostone or

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 rocks.
