Dolomite (/ ˈdɒl.əˌmaɪt, ˈdoʊ.lə -/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg (CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see Dolomite (rock)). An alternative name sometimes used for the dolomitic rock type is dolostone.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth’s crust.

2023年11月20日 · Dolomite is a mineral and a rock-forming mineral that is composed of calcium magnesium carbonate (CaMg(CO3)2). It is named after the French mineralogist Déodat Gratet de Dolomieu, who first described its properties in the late 18th century.

An important sedimentary and metamorphic mineral found as the principal mineral in dolostones and metadolostones, and as an important mineral in limestones and marbles where calcite is the principal mineral present.

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.

Dolomite forms essentially as a secondary mineral in carbonate rocks [see dolostone]. Primary dolomite can form due to direct precipitation from saline waters in evaporitic environment, both coastal and continental.

Most often found as a massive, white to buff or gray, carbonate rock-forming mineral, dolomite is one of the three most abundant carbonate minerals, calcite and aragonite being the other two. Dolomite differs from calcite and aragonite in its crystal structure.

2019年3月23日 · Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg (CO 3) 2. Its chemical formula can be more clearly written as CaCO 3.MgCO 3. Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite.

Dolomite, a carbonate mineral consisting mainly of calcium magnesium carbonate, is pivotal in various fields. From geology to industrial applications , understanding dolomite provides key insights into both the Earth's processes and human usage.
