Tufa is a rough, thick, rock-like calcium carbonate deposit that forms by precipitation from bodies of water with a high dissolved calcium content. Tufa deposition occurs in several known ways: – Mechanical precipitation by wave action against the shore. This form of tufa can be used for identifying the shoreline of extinct lakes (for example ...

Calcium Carbonate has the highest level of elemental calcium at 40%. Another use of calcium is as an antacid, as Calcium is an effective acid neutralizer. Calcium supplements are available in many forms, including soft chews, tablets, and liquids. Depending on the use of the calcium supplement, a range of particle sizes are required.
