What Is Coquina Stone

Coquina rock is a type of sedimentary rock (specifically limestone), formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth’s surface. In other words, the rock is formed by the accumulation of sediments.

What are the uses of coquina?

Coquina is commonly used as a building stone, particularly in places (such as Florida and the West Indies) with large coquina deposits. Coquina is a very soft building material, so soft that it needs to be dried out in the sun for a few years before being used as a building stone.

Where are coquina rocks found?

Significant deposits of coquina are found along the coasts of Florida and North Carolina. They also occur along the coasts of Australia, Brazil, Mexico and the United Kingdom. After deposition, calcium carbonate usually precipitates within the sediment.
