Coquina forms when shells, mineral calcite, and sometimes phosphate settle on the bottom of the ocean, while more and more pile upon them as time passes. Soon, as more pressure builds up, all the shells, mineral calcite, and phosphate press together to create a hard structure in the form of a rock called coquina.

∙ 15y agoCoquina is formed when mineral calcite, phosphate, shells, and shells of living things are squeezed together under pressure as more and more pile upon them as time passes. Later, cementation take place, cementing the particles of mineral calcite, phosphate, shells, and shells of living things together to create an organic rock called coquina.
