Many marine organisms, including corals, build skeletons from calcium carbonate – in the form of calcite or aragonite. The current composition of seawater favors the formation of aragonite – but soft ...

ALBUQUERQUE, N.M. — A calcite formation named Snowy River could prove a gold mine for scientists. Snowy River, believed to be the largest continuous calcite formation in the world, was discovered in ...

A calcite formation hidden in a southern Nevada cave has turned out to be one of the longest and most detailed climate archives ever found on land, preserving a near-continuous record that stretches ...

Computer simulations could help scientists make sense of a recently observed and puzzling wrinkle in one of nature's most important chemical processes. It turns out that calcium carbonate -- the ...
