What is limestone
Limestone, a versatile and widely used natural material, has been treasured for centuries due to its unique properties and aesthetic appeal. Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3).
Formed through the accumulation of ancient marine organisms, such as coral and shell fragments, it undergoes a process called lithification, transforming into the beautiful stone we know as limestone. This rock is typically formed in shallow marine environments, where the remains of organisms settle and compact over time.
The composition of limestone varies, but it predominantly consists of calcium carbonate in the form of calcite or aragonite. Alongside calcium carbonate, limestone often contains traces of other minerals, such as clay, silt, quartz, and organic matter. These additional elements contribute to the unique colors and patterns found in different types of limestone.
