Calcite as Limestone and Marble. Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.
Spar—Dogtooth and nailhead spar line bedrock or fill solution cavities in the walls, ceilings, and floors of Guadalupe caves. Dogtooth spar consists of scalenohedrons of calcite and nailhead spar is a more blunted form of calcite consisting of combined flat rhombohedrons and prisms which display uneven-sided triangular patterns.
The deposit is a Mississippi Valley Type (MVT) carbonate–hosted lead-zinc deposit. The mine was closed in 2002 due to failing metal prices and declining resources. Nanisivik had a population of 287 in 1996, but that had fallen to 77 in 2001, as the mine wound down, and is now zero.

Highly transparent calcite is called optical spar. Although calcite can form spectacular crystals, it is usually massive, occurring either as marble (p.301) or as limestone (p.319). It is also found as fibers, nodules, stalactites, and earthy aggregates. Calcite specimens can occur in metamorphic deposits, igneous rocks, and hydrothermal veins.
The transparent Iceland Spar variety, in which the double refraction is very apparent, was used as prisms for polarizing microscopes and other optical devices. Calcite also forms rocks that are used for ornamental purposes, such as marble and banded travertine or tufa. Calcite is also the main component of chalk, which is processed for drawing ...

calcite" and "calcite crystal" are used in place of "suboptical.") Calcite (calcium carbonate) is more familiar under such names as limestone, Carrara marble, chalk, travertine, or Mexican onyx. These forms occur in massive blocks of sedimentary deposits of minuscule crystals or grains (polycrystalline calcite).
Location: Calcite is one of the most wide-spread of all crystals and is found in virtually every country in the world. Clear/White Calcite is the most common variety. The most beautiful deposits of Clear Calcite are located in Iceland, hence the name "Icelandic spar," as well as in Mexico.
Calcite is transparent to opaque and may occasionally show phosphorescence or fluorescence. A transparent variety called Iceland spar is used for optical purposes. Acute scalenohedral crystals are sometimes referred to as "dogtooth spar" while the rhombohedral form is sometimes referred to as "nailhead spar".
