The impressive massif of the Dolomite Mountains in Northern Italy was formed almost entirely of CaMg(CO 3) 2, a calcium-magnesium carbonate mineral discovered in 1791 by the French naturalist Déodat de Dolomieu (), who gave name to both the mineral—dolomite—and to the impressive Alpine rocky landscape considered by …

Dolomite is used as a source of magnesia (MgO), a feed additive for livestock, a sintering agent and flux in metal processing, and as an ingredient in the production of glass, bricks, and ceramics. Dolomite …

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 …

In an ideal structure of dolomite, alternating layers of Mg 2+, Ca 2+ are interspersed with CO 3 2− groups oriented normal to the c-axis (Fig. 1), with a Mg/Ca molar ratio of 1 (stoichiometry) and an ordered arrangement.The larger radius Ca 2+ occupy A sites and the smaller radius Mg 2+ occupy B sites. The standard unit cell parameters of …

The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder and …
