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.

Dolomite Dolomite is one of the important minerals found in Missouri. The dolomite is made up of magnesium carbonate and calcium although it may also contain minor quantities of iron and manganese. Usually, the dolomite is found is a wide variety of colors such as …
The older these formations are in geological age, the more prone they are to weathering. Dolomite is particularly prevalent in the GCR and represent some of the oldest and most weathered karst landscapes on Earth [7]. Ground underlain by dolomite is hazardous due to the potential occurrence of subsidence (dolines) and sinkholes [11].
Dolomite is POSSIBLY UNSAFE for most adults when taken by mouth. Some dolomite products might be contaminated with heavy metals like aluminum, arsenic, lead, mercury, and nickel. Because of this concern, it might be wise to choose a safer calcium or magnesium supplement.

Frederick L. Schwab, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. IV.D Dolomite and Dolomitization. In many ancient limestones, the minerals calcite and aragonite have been partly or completely replaced by the mineral dolomite, producing replaced by the mineral dolomite, producing the rock dolostone (or traditionally, the rock dolomite).
Dolomite is a very common mineral, and is known for its saddle-shaped curved crystal aggregates. A unique, isolated Dolomite occurrence in Eugui, Spain has provided colorless transparent crystals that resemble the Iceland Spar variety of Calcite.The occurrence of Kolwezi, in the Congo, has produced some fascinating, cobalt-rich specimens that are a beautiful hot pink color and highly popular.
LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Additionally, because lime and dolomite are alkaline, they help to raise the soil’s pH back to a level that is conducive to growing plants. Regardless of whether or not you suspect that your soil may be too acidic, it’s always a good idea to have a sample of the dirt tested on an annual basis.
Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.
