Description: Calcite is an abundant mineral found in many geological environments. It forms by precipitation from ground and surface waters, forming the major component of marls and limestone in the ocean, lakes and rivers. It also forms speleothemes in caves, euhedral crystals in vugs, and tufa where springs emerge on the surface.

Britannica, dictionary defines marble as granular limestone or dolomite that is rock composed of calcium-magnesium carbonate. It has been recrystallized under the influence of heat, pressure, and aqueous solutions. Commercially, it includes all decorative calcium-rich rocks that can be polished, as well as certain serpentines and antiques.

While granite, quartzite, and marble are all forged deep within the earth's crust, onyx is born right on the surface. Onyx forms from spring water or groundwater that has an abundance of calcite dissolved in it. When this water emerges at the mouth of a spring, the minerals precipitate out and build a crust of calcite crystals.

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.

How is limestone formed and where is it found? Most fresh water and sea water contain dissolved calcium carbonate. All limestones are formed when the calcium carbonate crystallizes out of solution or from the skeletons of small sea urchins and coral. .Such evaporation takes place in the hot lagoons of many coral reefs and in most shallow tropical seas.
