► Introduction: Calcite is found everywhere, in pretty much all parts of the world. Marble and limestone are made up primarily of calcite, and calcite actually makes up a large portion of the Earth’s crust. Marine microorganisms contain calcite and when they die, then fall to the ocean floor, over time, these calcite shells go into creating limestone. In ancient prehistory, trilobites had eyes with clear calcite lenses. Study of the Phanerozoic Period reveals calcite seas and aragonite seas, seas which were home to a multitude of invertebrate organisms safely protected in calcite shells. Egg shells, coral and pearls also contain forms of calcite.
