Calcite (and Aragonite) | Common Minerals

Rocks composed primarily of calcite, such as limestone and marble, are also extensively quarried as decorative building stones and for sculpture. Because of the ease with which calcite reacts with even weak acids, calcite is used to balance soil acidity, in water treatment, and as a calcium supplement in animal feed.
