Calcite Minerals Education Coalition

Calcite is the mineral component of limestone which is used primarily as construction aggregates, and in production of lime and cement. Limestone also is used in a variety of commercial applications including: road construction, riprap and jetty stone, filter stone, railroad ballast, poultry grit, mineral food, sugar processing, flux stone in

Introduction: calcite occurs in a great diversity of parageneses and geological settings. It is an important rock-forming mineral (e.g. as the major constituent of limestone); it is a widespread product of low to medium-grade metamorphism and hydrothermal alteration in many rock-types and it is a common hydrothermal vein-mineral.

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 double refraction in

Relief: Low to high; twinkling; variable relief. Habit/Form: Crystals of calcite have many habits but usually consist of combination of scalenohedrons and rhombohedrons. However, in most rocks, calcite forms anhedral grains or aggregates of grains. Fossil shells and thin veins may be fibrous or columnar.

Calcite Wikipedia

Etymology. 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.. When applied by archaeologists and stone trade professionals, the term alabaster is used not just as in geology and mineralogy, where it is reserved for a variety of

Calcite Raman spectrum Romanian Database of Raman

Jan 17, 2017· The lower wavenumbers of calcite (285 cm-1) observed in the above table, arise from the external vibration of the CO 3 group that involve translatory oscillations of the group (relative translations between the cation and anionic group). In this spectrum are no values below 200 cm-1 because the spectral range is between 200 3400 cm-1.. A weak line observed at 1749 cm-1 may be regarded as

Calcite an overview ScienceDirect Topics

Calcite is the most common mineral of hydrothermal caves developed in carbonate rocks. In addition, such minerals as quartz, barite, fluorite, and sulfides are commonly reported from the deep-seated hydrothermal caves. (Ore-related hydrothermal karst, where the list of minerals can be quite large, is not considered here.)
