Limestone is formed almost exclusively by organisms in seawater (although there are some freshwater limestones too), either, by direct crystallization of dissolved calcium and carbonate to form shells, or as a byproduct of the presence of organisms in seawater (which can alter the overall geochemical setting).

Limestone is a sedimentary rock formed mostly of calcium carbonate. The stone can be formed by a hydrological process, dissolving calcium carbonate in carbon dioxide, or by a biological process, accumulating calcium carbonate through fossil sediments. The result of both processes gives rise to a large number of types of limestone, as shown in the examples below. Types of white limestone. .

A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos, though strictly speaking a cave is exogene, meaning it is deeper than its opening is wide, and a rock shelter ...

In this process, limestone is first broken up to reduce its size. Then it is washed and taken to kilns to be heated through a three step process: preheating, calcining, and cooling. Once cooled, the quicklime is crushed and then water is added. Type S and SA limes are commonly used in mortar mixes for construction. Depending on the production method, highcalcium or dolomite hydrated lime can ...
