Shelly limestone

Each shelly limestone is unique in its own way, where every stone of this type is composed of different fossilized organism and shell fragments.

The unique qualities of a shelly limestone are formed with the help of calcite, acting as a sticking agent for small shell fragments, dead marine organism and other minerals.

The appearance of shelly limestones can differ in color, composition, hardness and texture depending on where the stone is formed.

In detail, shelly limestones are formed when rocks containing different minerals get weathered down then get transported to a standing body of water.

Due to the stones high calcium carbonate content, it can also be used in the agricultural industry as an agent that helps reduce acidity in soil.
