  Chalk is a type of limestone that is white in color. It is formed from the skeletons of tiny marine creatures known as coccolithophores. Chalk is found in the ground and cliffs of North West Europe, especially in England. It is also used as a material for writing and drawing.

• Coquina

  Coquina is a type of limestone made from shells and coral debris cemented together. It is often found in coastal areas and can be identified by its shelly appearance. Coquina is a soft stone that is easily worked but lacks the durability of other limestones.

• Fossiliferous Limestone

  This limestone contains fossils of marine organisms like corals, shells, and algae. The fossils are visible to the naked eye. Fossiliferous limestone is evidence of the sediments that formed it, which were rich in marine life.

• Oolitic Limestone

  Oolitic limestone is a type of limestone composed of small, round particles called ooids. The ooids are formed from calcium carbonate that circulates in water. These particles are cemented together to form oolitic limestone. The water has to be warm and shallow for ooids to form. Oolitic limestone is found in areas like the British Isles and the USA. It is also used for building and making lime.

• Purbeck Limestone

  This type of limestone is mainly found in the Isle of Purbeck. It is a fossiliferous limestone with layers of chalky limestone and clay. Purbeck limestone is used to make buildings and monuments. It is also used to make lime products.

• Travertine

  Travertine is a metamorphic rock that is formed by the precipitation of calcium carbonate in hot springs and caves. It is a porous type of limestone with holes and cracks. Travertine is used for flooring, countertops, and other architectural details because of its beautiful appearance. It is also classified into Spanish, Mexican, and Roman travertine, based on where it is found.

• Marble

  Marble is a metamorphic rock that forms when limestone undergoes extreme heat and pressure. It is composed of interlocking crystals of calcite. Marble is highly valued for its beauty and is used in sculptures, and high-end flooring. It can also be white, black, pink, or green, based on its mineral content.
