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 properties. 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,A Raman spectroscopic comparison of calcite and dolomite,,Furthermore, the structure of calcite and dolomite is of greater interest because a number of important mineral constituents of sedimentary rocks, including magnesium and iron-bearing carbonate, have structures that are identical with or closely related to the calcite pattern .Calcite dolomite | Article about calcite dolomite by The,,A carbonate rock with a composition of 10-50% calcite and 90-50% dolomite.

Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.dolomite | Formation, Structure, Properties, Uses, & Facts,,Dolomite: 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. Learn more about the structure, properties, and uses of dolomite in this article.Calcite and Dolomite - University of Pittsburgh,Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.
