Calcium carbonate is one of the most abundant materials present in nature with the chemical formula CaCO3. Calcium carbonate also called limestone is an example of a metal carbonate .

Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water. Lithographic limestone is a type of limestone that contains fossils.

Limestone forms by sedimentation of coral and shells (biological limestone) or by the precipitation of calcium carbonate (sedimentary chemical limestone) from in marine waters. Limestone comes in many forms (e.g. chalk, coquina, fossiliferous, lithographic, oolitic, travertine, tufa). It can be crystalline, clastic, granular or massive ...

The presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a constant pH because the minerals react with the excess acid. However, acid rain eventually can overcome the buffering capacity of the surface water. Back Compass Index Tables Introduction Next

Its chemical formula is CaCO3 and it is where many fossils are found. Calcium carbonate is limestone that contains at least 95 percent calcium and magnesium limestone is limestone in which some of the calcium has been replaced with magnesium. Limestone is an acid sensitive stone, similar to marble.

Limestone composition and reactivity are critical factors that determine the performance of limestone-based wet flue gas desulfurization systems. Limestone quality affects sulfur dioxide (SO2 ...

Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure. Limestone and other products derived from it are used extensively in the construction industry and to neutralise acidic compounds in a variety of contexts.
