Dolomite and Quartz

Dolomite (pronounced as ˈdolemait’) is the name given to a sedimentary carbonate rock and a mineral. Dolomite and Quartz, both are composed of calcium magnesium carbonate CaMg(CO3)2 which is found in crystal.
Dolomite rock (also dolostone) is mainly composed of the dolomite mineral. In this composition Limestone which is partially replaced by dolomite is given the name “dolomitic limestone”, or as per old U.S. geologic literature it is called as magnesian limestone. Dolomite mineral got its first narration in 1791 as a rock by the French naturalist and geologist, Déodat Gratet de Dolomieu (1750–1801) for exposures in the Dolomite Alps of northern Italy.
Dolomite mineral finds its application as an ornamental stone, a concrete aggregate and as a source of magnesium oxide. It is a very vital petroleum reservoir rock, and is used as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals (that is, readily oxidized metals) such as lead, zinc, and copper. If calcite limestone is uncommon or too costly at some places then dolomite sometime takes its place as a flux (impurity remover) for the smelting of iron and steel. The Large quantities of processed dolomite finds place in the plants for the production of float glass (flat glass). In horticulture, dolomite and dolomitic limestone are mixed with soils to lower their acidity ("sweeten" them). The most common examples of its usage are Home and container gardening.
The Quartz Group is a combination of all those ways in which SiO2 can be organized into a neutral structure. It is quite amazing to know that there are 9 ways of organizing SiO2, referred to as silicon dioxide or silica. Quartz Mineral Group is also alternatively called as the Silica Group. Silicon and oxygen are the two most abundant elements on Earth's crust that may be reason that their diverse modes of organization are not so unexpected. But actually it is simply an end product of the temperature and pressure, especially at the time of crystallization that decides the fate of SiO2 which form silicon dioxide will organize into.
