Dolomite is a calcium element or magnesium element carbonate mineral. CaMg (CO3)2 is the formula unit composition. The trigonal crystal system of dolomite has a rhombohedral habit. Unlike magnesian calcites, calcium and magnesium are divided into complete separate planes in ideal dolomite.
Dieudonné Dolomieu, also called Déodat De Gratet De Dolomieu, (born June 23, 1750, Dolomieu, near Tour-du-Pin, Fr.—died Nov. 26, 1801, Château-Neuf, Saône-et-Loire), French geologist and mineralogist after whom the mineral dolomite was named. A member of the order of Malta since infancy, he was sentenced to death in his 19th year …

Les alvars sont des habitats naturels ouverts, composés de calcaire ou de dolomie, parfois recouverts d'une mince couche de terre. The mineral dolomite is commonly found in deposits of a sedimentary rock called dolostone. La dolomite minérale est généralement trouvée dans les dépôts d'une roche sédimentaire appelée le dolostone.

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.
Descrizione. Questa roccia prende il suo nome (come il minerale dolomite) dal naturalista e geologo francese Déodat Gratet de Dolomieu (1750–1801), il quale osservò tale roccia nei gruppi montuosi delle Dolomiti.. Quando in un calcare la calcite è parzialmente sostituita da dolomite, esso viene chiamato calcare magnesiaco, calcare dolomitico o dolomia …

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 …
The examined dolomite is composed of 98% of mineral dolomite and 2% of calcite. Other silicates (i.e. quartz) exist only in trace amounts. This dolomite presents intense orange luminescence colour, indicating the absence of impurities and thus high purity. Its chemical composition is: CaO=32.9%, MgO=20.2%, CO2=46.7%, others=0.14% and its isotopic …

The original mineral name 'dolomie' was given by NT Saussare, in 1792, in honor of the French geologist Deodat Guy de Dolomieu (1750–1801). Dolomite, the rock, contains a large proportion of dolomite the mineral. Ideal dolomite has a crystal lattice consisting of alternating layers of Ca and Mg, separated by layers of CO3 and is typically ...
