How Do Snails (And Other Molluscs) Create Their Shells?
Calcite is the stable form of calcium carbonate, while aragonite is metastable, which means that it is stable under normal conditions, but can convert to the more stable calcite form. Interwoven between the minerals is protein. That protein gives strength, flexibility, and the lightweight quality of the shell. After all, snails can't lug ...

Petrifying Climate Change
When the calcium or magnesium ions combine with carbon dioxide, they form calcite or magnesite. The chemical reaction is similar to how many marine organisms build their shells. But by introducing a third ingredient, electricity, Sant and his team can make that reaction happen quickly, efficiently and, perhaps eventually, on a large scale.

How does mine drainage occur? | U.S. Geological Survey
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
