Calcite: The mineral Calcite spar information and pictures

Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperature

Calcite Calcite is the only common non-silicate rock forming mineral, being instead calcium carbonate. It has two refractive indices causing a significant double refraction effect - when a clear calcite crystal is placed on an image, a double image is observed; See the sample below. Calcite will fizz when dilute hydrochloric acid is placed on it. It may be fluorescent, phosphorescent ...

The "Acid Test" for Carbonate Minerals and Carbonate Rocks

1) In mineral identification labs, some students are ready to call any mineral that produces an acid reaction "calcite" or another carbonate. However, calcite is a ubiquitous mineral and it is often present as an intimate part of other mineral specimens and rocks. These can produce a false acid reaction. To avoid being misled, students should always be cautioned to confirm a

Using Characteristics of Minerals to Identify Them - ISGS

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity. Hardness. The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. Hardness is determined by the ability of one mineral to scratch another. Federick
