Limestone

 

What is Limestone?

The main component of limestone, a sedimentary rock, is calcium carbonate (CaCO3) in the form of calcite. Based on its formation, composition, and other characteristics, limestone has a variety of names such as Chalk, Tufa, Ordovician, and Grainstone. Limestone can be used as a decorative element or as a building material, a component of concrete, or a white pigment in products.

Formation

Approximately 40% of Kuala Lumpur is covered with limestone, which is thought to be 6000 feet thick and responsible for the formation of most of the surrounding area. These sediments were folded into troughs by orogenic movement, and the exposed granite cores between them were exposed by erosion to create limestone hills. The Batu Caves is a well-known limestone hill in both geology and religion. Evaporation causes limestone to continuously develop in the caves. When the water evaporates, calcium carbonate that was dissolved in it is deposited on the cave roof. They are referred to as stalactites. A stalagmite would form if water drops fell there and evaporated, rising higher from the cave floor. In shallow, calm marine waters, limestone can also be formed.
