Dolomite (mineral) Wikipedia

The mineral dolomite was probably first described by Carl Linnaeus in 1768. In 1791, it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu (1750–1801), first in buildings of the old city of Rome, and later as samples collected in the mountains now known as the Dolomite Alps of northern Italy. Nicolas-Théodore de Saussure first named the mineral (after

dolomite Formation, Structure, Properties, Uses, & Facts

Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO 3) 2].. General considerations. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth’s crust. The bulk of the dolomite constitutes dolostone formations that occur as thick units of great areal extent in many sequences of

University of Minnesota’s Mineral Pages: Dolomite

By far though, most dolomite occurs in altered sedimentary marine rocks called dolostones or in marbles formed from the metamorphism of dolostone. Because dolostones are composed primarily of the mineral dolomite, geologists once used the term ‘dolomite’ for both the mineral and the rock.

Dolomite is massive and has fibrous crystalline habits. It is a significant mineral in the carbonate rock, and its properties are similar to that of calcite. Its hardness is measured from 3.5 to 4 on the Mohs scale. Dolomite too holds a vitreous lustre, as its transparency ranges from transparent to translucent

Dolomite: The mineral dolomite information and pictures

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 beautiful hot pink color and highly popular.

Dolomite Complete Mineral Overview

Crystal Structure of Dolomite. 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.

The syn-depositional formation of these dolostones was indicated by their rock-mineral features and syn-sedimentary deformation stage. The dolomite was composed of relatively poorly ordered proto-dolomite crystals with micron-sized spherical or sub-spherical morphology and coexisted with hydrothermal minerals, including analcime, buddingtonite

Sweet Spot for the Formation of Sedimentary Dolomite

Ideal or stoichiometric dolomite mineral (CaMg[CO 3] 2) has an ordered structure with alternating Ca 2+ and Mg cation layers along the c-axis. However, dolomite minerals in sedimentary rocks display a wide range of composition and Ca-Mg ordering. Natural dolomite minerals range from ~ 38 to ~ 50 mole % of MgCO 3 with a bimodal composi-

Dolomite: occurrence, evolution and economically important

Nov 01, 2000· The original mineral name dolomie was given by N.T. Saussare, in 1792, in honor of the French geologist Deodat Guy de Dolomieu (1750–1801) and was first applied to rocks in the Tyrolean Alps (Bourrouilh-Le Jan, 2000).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
