Calcite is composed of calcium carbonate (CaCO3) while dolomite is a calcium magnesium carbonate (CaMg(CO3)2). These two minerals are one of the most common pairs to present a mineral identification challenge in the field or classroom. The best way to tell these minerals apart is to consider their hardness and acid reaction.
Palepink cobaltian (?) dolomite, pseudomorphous after calcite. The calcite in this specimen was in the form of stacks of lenticular (flattened rhombohedral) crystals, which accounts for the "knotty" appearance of the dolomite surface.. The matrix consists of layered dolomite with a little darkgreen duftite (?).
biotite, calcitegraphite, and calcitedolomite thermometry in the Grenville Orogen in Canada. Although calcitedolomite pairs yielded lower temperatures in comparison with the other two thermometers, resulting temperatures agreed quite well, if care was taken to use only calcite grains with no visible dolomite exsolution.
In a threeyear study by University of Missouri scientists, however, "no significant difference was found between calcite and dolomite lime," and the researchers concluded: "Cotton farmers should not be concerned about potential negative effects of magnesium in dolomite lime material."
Difference Between Calcite and Dolomite, Calcite vs Dolomite Dolomite and calcite are minerals containing calcium carbonate Both of these are hard to distinguish from each other except for few properti Calcite Calcite is a mineral, which contains calcium carbonate (CaCO 3) This is an abundant mineral on the earth surface Calcite can form rocks, and they may grow up to large .

Jun 12, 2000· Atomistic computer simulation methods have been employed to model the structure of the (10{bar 1}4) surfaces of calcite, dolomite and magnesite. The authors calculations show that under vacuum conditions, calcite undergoes the greatest degree of surface relaxation with rotation and distortion of the carbonate group accompanied by movement of the calcium ion.
Sep 27, 2018· Dolomite is a form of limestone, rich in approximately equal parts of magnesium carbonate and calcium carbonate. It is found widely throughout the world. Dolomitic limestone contains about five times as much magnesium and five eighths as much calcium as ordinary limestone.

Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a ...
