GEOLOGY

Detailed explanation-1: -Travertine is a sedimentary rock that consists principally of calcite, the hexagonal form of calcium carbonate (CaCO3). It is formed by calcium carbonate separating from shallow or surface waters by a process of rapid precipitation. The trigger for the precipitation is usually a gain or loss of carbon dioxide (CO2).

Detailed explanation-2: -It is a natural sedimentary rock that is most often found in Italy but travertine deposits are also common in Turkey, Mexico, Peru, Croatia, Iran and even China. It is also found in the USA but most of the material used there is imported.

Detailed explanation-3: -Introduction. Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.

Detailed explanation-4: -The second way limestone is formed is when water containing particles of calcium carbonate evaporate, leaving behind the sediment deposit. The water pressure compacts the sediment, creating limestone. The area around the Great Lakes, such as Michigan, Indiana, and Illinois, has a large amount of limestone.
