Calcite: Mineral information, data and localities.

Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties. NOTE on the unit cell and the Miller indices ...

[PDF] Karl Przibram: Radioactivity, Crystals, and Colors | Semantic …

Karl Przibram is one of the pioneers of early solid state physics in the field of the interdependence of coloration effects and luminescence in solids (crystals, minerals) induced by radiation. In 1921 Przibram discovered the effect of radio-photoluminescence, the light-stimulated phosphorescence in activated crystals induced by gamma rays. In 1926 Przibram was the first to use the term ...

Calcite

Calcite is derived from the German Calcit, a term coined in the 19th century from the Latin word for lime, calx (genitive calcis) with the suffix -ite used to name minerals. It is thus etymologically related to chalk. Calcite and Aragonite are polymorphous to each ...

Birefringence

Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.[1] These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the ...

Calcite

Calcite. Calcite is a usually white, clear, pale-yellow or blue orthorhombic mineral. Calcite occurs in many different forms and is the main component of chalk, limestone, and marble. It is a polymorph of aragonite. It is a rock-forming mineral with a chemical formula of CaCO 3.

Calcite Deformation. Calcite is one of three groups of minerals formed by the carbonate anion (CO 3) 2- and the most common polymorph of Calcium Carbonate (CaCO 3 ). Aragonite and Vaterite are other polymorphs which are metastable at the Earth''s surface. Other polymorphs have been observed under experimental laboratory conditions.
