Study shows calcium carbonate takes multiple, simultaneous roads to different minerals, provides insight into trapping carbon dioxide in underground rock.
Visitors to the Western Wall in Jerusalem can see that some of its stones are extremely eroded. This is good news for people placing prayer notes in the wall's cracks and crevices, but presents a problem for engineers concerned about the structure’s stability.
What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers — organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection.

Carlsbad Caverns National Park is located in southeastern New Mexico in the United States. The park holds 46,766 acres of land, of which 2/3 is a designated wilderness, and is thought to have been discovered by Jim White, who entered the Carlsbad Caverns and named many of the areas within the caverns, including Queens Chamber, New Mexico Room, Green Lake Room, Giant Dome, Witch's Finger, and Bottomless Pit. President Calvin Coolidge established the area as a national monument in 1923, but it...
Aragonite is a polymorph of the mineral calcite, both having the chemical composition CaCO3. Its structure differs from calcite and leads to a different crystal shape, an orthorhombic system with acicular crystals. By repeated twinning pseudo-hexagonal forms result. It may be columnar or fibrous, occasionally in branching stalactitic forms called flos-ferri (flowers of iron) from their association with the ores at the Carthinian iron mines. The type location for aragonite is Molina de...
he mineral calcite is a calcium carbonate corresponding to the formula CaCO3 and is one of the most widely distributed minerals on the Earth's surface. It is a common constituent of sedimentary rocks, limestone in particular. It is also the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs, and also occurs in caverns as stalactites and stalagmites. Calcite is often the primary constituent of the shells of marine organisms (e.g. plankton,...
Dolomite is a mineral (formula CaMg(CO3)2) consisting of a calcium magnesium carbonate found in crystals and in beds as dolostone. A pure form of dolostone would be rare, however; it usually intergrades with limestone and is referred to as dolomitic limestone, or in old U. S. geologic literature as magnesian limestone. Dolomite has physical properties similar to those of the mineral calcite, but is less soluble in hydrochloric acid. There is uncertainty as to the cause of its formation,...
Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate). The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze (see lysocline for information on calcite dissolution). Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites...
