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 unevensided triangular patterns.

Location: Calcite is one of the most widespread 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.
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 ...

OPTICAL CALCITE DEPOSITS IN PARK AND SWEET GRASS COUNTIES, MONTANA By W. C. STOLL AND FRANK C. ARMSTRONG ABSTRACT The calcite deposits of Park and Sweet Grass Counties, Mont., although mined locally for chicken grits, had yielded only slightly more than 600 pounds of optical spar and mineral specimens before World War II.
Helgustadir calcite was soon in demand throughout Europe''s scientific community. While the Danish parliament under Frederick III gave its permission for calcite mining at Helgustadir, no largescale to recover Iceland spar effort was made for many two centiuries.

Highly transparent calcite is called optical spar. Although calcite can form spectacular crystals, it is usually massive, occurring either as marble () or as limestone (). It is also found as fibers, nodules, stalactites, and earthy aggregates. Calcite specimens can occur in metamorphic deposits, igneous rocks, and hydrothermal veins.
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".

The deposit is a Mississippi Valley Type (MVT) carbonate–hosted leadzinc 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.
Spar is an old mining or mineralogy term used to refer to crystals that have readily discernible faces. A spar will easily break or cleave into rhomboidal, cubical, or laminated fragments with smooth shiny surfaces.. The various spar minerals were a historical term among miners and alchemists for any nonmetallic mineral akin to gypsum, known in Old English as spærstān, spear stone, referring ...
