Spar (mineralogy)

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 ...

Geology and ore deposits of the Whitepine area, Tomichi ...

The Tomichi mining district is on the western slope of the Continental Divide near the southern end of the Sawatch Range in southeastern Gunnison County, Colorado. The most productive part of the Tomichi district was the Whitepine area. It is estimated that since the discovery of ore in 1879 the area has produced approximately $7,000,000, principally in lead and zinc, with lesser amounts of ...

Calcite Mineral | Uses and Properties

Calcite is a rock-forming mineral with a chemical formula of CaCO 3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. These rocks are ...

Iceland spar, a clear, pure, colorless variety of calcite, has been found at the Twin Chimneys Mine in Mercer County; other localities near Mundys Landing and the Chinn Mine might contain optical calcite as well. Aragonite is a polymorph of calcite and is distinguished from calcite by a higher specific gravity (2.95) and hardness (3.5

Cave Spar

Subaerial spar and pool spar crystals tend to be smaller, as stable conditions may be short-lived in those environments and the degree of water saturation gets too high. Phreatic spar has the best combinations of these conditions, so forms most of the large spar seen in caves. Calcite is most frequently encountered as cave spar, and some of these
