Definition of calcite in English:

calcite

noun ˈkalsʌɪtˈkælˌsaɪt

mass noun

A white or colourless mineral consisting of calcium carbonate. It is a major constituent of sedimentary rocks such as limestone and is deposited in caves to form stalactites and stalagmites.
Example sentencesExamples

- Around one corner, the mine became snow white with calcite and sodium chloride.
- This cavity may then be filled with coal, calcite, siderite, or any other form of sediment.

- Other than clay minerals, calcite and pyrite are the most common secondary minerals present.
- The calcite and other such minerals suffered greatly from exposure to the weather.
- Zeolite veins appear to be later than prehnite veins, and calcite is the last mineral to form veins in the dyke samples.
- The limestone is highly fractured and contains abundant calcite and quartz veins.
- Abundant thin calcite and quartz veins cut the schists, and have been boudinaged and rotated parallel to the first cleavage.
- The major mineral constituents of coal balls are calcite, dolomite, ferroan dolomite and pyrite.
- Analcime may also be associated with quartz crystals, calcite, and common opal.
- In some geodes, the brown calcite is completely hidden by clear calcite secondary growth.
- Matrix minerals of the septaria are ferroan dolomite, quartz, calcite, and pyrite.
- The main gangue minerals that make up the vein are massive white calcite, quartz, and prehnite.
- The calcite formed scalenohedral and rhombohedral crystals on some of the quartz crystal groups.
- Strontium concentrations in seawater reflect the diagenesis of Sr-rich aragonite to calcite on continental shelves.
- The sparry calcite is interpreted as a single phase of precipitation that infilled external moulds of the arthropod.
- The walls of the cave were clean white limestone and decorated with pretty cave flowers and calcite crystals.
- Specimens of this unusual calcite are on display at the Mineral Museum.
- Quartz is the dominant mineral in veins in siliceous rocks, calcite in limestones, and gypsum in gypsiferous sediments.

The arms of ophiuroids and crinoids (phylum Echinodermata) are supported by calcitic ossicles reminiscent of vertebral centra.
Example sentencesExamples
- The remaining carbonate bioclasts are exclusively calcitic echinoid spines, rare foraminifera, molluscs and bryozoan fragments.
- In Conchicolites the vesicular shell structure is absent and the calcitic prisms are deposited at the shell aperture more or less at right angles to the longitudinal shell axis.

- Some of the most attractively preserved fossils are the yellow and brown calcitic moulds of ammonites that are characteristic of calcareous concretions.
- Having a thick, amorphous, calcitic layer of shell material, these gastropods stood a better chance of preservation than other groups of mollusks that obviously must have shared their geographic distribution throughout the Tertiary.
- The generic assignment remains questionable, however, because right valves are unknown, and because the specimens appear to lack the prismatic and crossed-foliated calcitic microstructures that are broadly present in the family.
- Modern pinnids are morphologically and microstructurally nearly symmetrical, with the same calcitic regular simple prismatic structure comprising a layer of similar thickness in the left and right valves.
- The specimens are preserved as mostly fragmental, three-dimensional, fully to partially testiferous, internal molds formed as, or in association with, sideritic or calcitic concretions.
- At Lawson Cove there are many collections that yielded trilobites, conodonts, organophosphatic brachiopods (this report), and calcitic brachiopods, but no graptolites.

- Concretions, which were originally calcitic, are either weathered out or now contain epidote as a cement.
- The calcitic ossicles of crinoids, as is typical of echinoderms, form an internal skeleton that provides support and protection.
- The formerly aragonitic specimens are preserved as moulds and the calcitic faunal elements are usually partly decalcified.
- All tyrannosaurid and hadrosaur bones lie horizontally within a 20 cm thick blocky, green claystone with occasional calcitic nodules and vertical to subvertical burrows.
- At most localities, only the outer prismatic calcitic shell layer is preserved, although some specimens retain the recrystallized inner shell layer.
- Remnants of outer calcitic shell layer show a polygonal pattern indicating original presence of columnar prismatic structure; inner aragonitic layers not preserved.
- The Atlantic and Gulf Coastal Plains of the United States contain assemblages preserved as original aragonitic and calcitic material in unconsolidated sediments.
- Like all echinoderms, echinoids are pentaradially symmetrical, have a water-vascular system, and have an internal skeleton made of calcitic ossicles (plates).
