There is even a stalactitic form of calcite found in limestone caves. These elongated, icicle-shaped formations hang from cave ceilings, formed over time by the slow drip of water.

Researchers found that Bacillus megaterium can turn over 94% of CO₂ into solid rock using a clean, non-ammonia process.

A chunk mined by Indiana Limestone Company, founded in 1926, one of the foremost purveyors of this special stone. National Museum of Natural History The Hoosier State’s first commercial ...

The grinding tip of the sea urchin tooth exhibits exquisite control over calcite crystal orientation and Mg distribution. Proceedings of the National Academy of Sciences , 2009; 106 (15): 6048 DOI ...

The study uses computer models to see possible effects of spraying small calcite particles about 12 to 15 miles above the Earth's surface in a region about 30 degrees north and south of the equator.

The results are in some cases remarkable, even in relation to biology, and are of great interest and importance in the study of limestone rocks and their included fossils, since subsequent changes ...

Many rivers and streams flowing onto a limestone outcrop will lose almost all water to the underground. The water can flow directly into caves or can be lost through fissures, joints, and sinkholes.
