n.
A common crystalline form of natural calcium carbonate, CaCO3, that is the basic constituent of limestone, marble, and chalk. Also called calcspar.

calcite

(ˈkælsaɪt)
n
(Minerals) a colourless or white mineral (occasionally tinged with impurities), found in sedimentary and metamorphic rocks, in veins, in limestone, and in stalagmites and stalactites. It is used in the manufacture of cement, plaster, paint, glass, and fertilizer. Composition: calcium carbonate. Formula: CaCO3. Crystal structure: hexagonal (rhombohedral)
calcitic adj

cal•cite

(ˈkæl saɪt)

n.
a common mineral, calcium carbonate, CaCO3, found in a great variety of crystalline forms: a major constituent of limestone, marble, and chalk.

cal·cite

(kăl′sīt′)
A usually white, clear, or pale-yellow mineral consisting of calcium carbonate. It occurs in many different forms and is the main component of chalk, limestone, and marble. Calcite is the mineral used to represent a hardness of 3 on the Mohs scale.

We argue that calcite prism growth in euheterodonts is dominated by abiotic constraints whereas, in pteriomorphs (such as oysters, pterioids, and mussels), it is under strong biological control.
Based on the XRD analysis four different, major mineral phases were identified including; calcite, quartz, ankerite and dolomite.
The Olympus BH@ BHSP polarizing microscope equipped with Nikon digital camera was used to characterize the mineralogical, texture, cementing material and grain features (grain size of calcite and dolomite in relation to boundary shapes).
It is generally accepted that the preservation conditions of calcitic belemnite rostra, which are distinguished by their original low-magnesium calcite composition, makes them relatively stable and resistant to diagenetic alteration (Veizer, 1974; Sslen, 1989; Podhala et al.
By using Ordovician carbonatite rocks and paleokarst fissure/cave-filling calcite as study subjects in addition to carbon-oxygen and strontium isotopes and trace element techniques, this study attempts to examine the development of paleokarst reservoirs and the larger paleoenvironment to provide geochemical evidence for the exploration and development of karst reservoirs.
