The carbonates consist mainly of calcite which contains up to 11 mole % (MgCO 3 +FeCO 3). Some of the calcites are characterized by skeletonlike dolomitic exsolutions of rhombohedral shape that are orientated on rhombohedron planes of the calcite matrix. The relations between metamorphic grade and calcite composition will be discussed.

As nouns the difference between talc and mica is that talc is a soft mineral, composed of hydrated magnesium silicate, that has a soapy feel and a greenish, whitish, or grayish color, and usually occurs in foliated masses while mica is any of a group of hydrous aluminosilicate minerals characterized by highly perfect cleavage, so that they readily separate into very thin leaves, more or less ...

Carbonatite is a unique type of intrusive igneous deposit which is rich in calcium carbonate (calcite, CaCO 3) and minerals of the carbonate carbonate is typically burned out of igneous materials by intense heat; the preponderance of calcite found in carbonatite therefore makes it a very unusual type of igneous formation.

eventually magnesite (MgCO3). The terms "periclase," "brucite," "hydromagnesite," and "magnesite" are mineral names and should, therefore, be restricted to naturally occurring forms of materials that meet all other requirements of the definition of a mineral (see, for example, Bates and Jackson 1984).

The carbonates include minerals in which the anion is the CO 3 –2 complex. The carbonate combines with +2 cations to form minerals such as calcite (CaCO 3), magnesite (MgCO 3), dolomite ((Ca,Mg)CO 3), and siderite (FeCO 3). The copper minerals malachite and azurite are also carbonates. In phosphate minerals, the anion is the PO 4 –3 complex.

Magnesium is located both in clay minerals and associated with cation exchange sites on clay surfaces. Clays such as chlorite, vermiculite, and montmorillonite have undergone intermediate weathering and still contain some Mg as part of their internal crystal structure. The .

The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric acid is .

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used .

Calcite CaCO 3 Named as a mineral by Gaius Plinius Secundus (Pliny the elder) in 79 from Calx, Latin for Lime, Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380470 °C, and vaterite is even less stable.
