Limestone is a calcareous sedimentary rock formed at the bottom of lakes and seas with the accumulation of shells, bones and other calcium rich goods. It is composed of calcite (CaCO3). The organic matter upon which it settles in lakes or seas, are preserved as fossils. Over thousands and millions of years, layer after layer is built up adding weight. The heat and pressure causes chemical reaction at the bottom and the sediments turn into solid stone, the limestone.

If part of the calcium molecule is replaced by magnesium, it is known as magnesium lime stone or dolomite limestone.

• It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar.
• Pulverized limestone is used as a soil conditioner to neutralize acidic soils.
• It is crushed for use as aggregate—the solid base for many roads as well as in asphalt concrete.
• As a reagent in flue-gas desulfurization, it reacts with sulfur dioxide for air pollution control.
• Glass making, uses limestone.
• It is added to toothpaste, paper, plastics, paint, tiles, and other materials as both white pigment and filler.
• It can suppress methane explosions in underground coal mines.
• Purified, it is added to bread and cereals as a source of calcium.
• Calcium levels in livestock feed are supplemented with it, such as for poultry & bovine.
• It can be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to restore essential nutrient levels.
• Used in blast furnaces, limestone binds with silica and other impurities to remove them from the iron.
• It is used in medicines and cosmetics.
• It is used in sculptures because of its suitability for carving.

The southern part of the Panamint Range outside of Death Valley is unique in providing a very pure pre-cambrian source of limestone and dolomite. The PVL quarry is uniquely located and qualified to provide extraction of 4 grades of material.
