Limestone

Limestone is a sedimentary rock made up mostly of mineral calcite substance. This form of stone is important stone for all types of masonry and architecture developments, vying with only granite and sandstone to be the most commonly used architectural stone and also is used for a wide range of interior and exterior building purposes. Limestone is quarried from various locations and millions of years ago it would have been the bedrock for creating the floor of a shallow area of the sea.
