Calcium carbonate - Wikipedia
Calcium carbonate is a stone compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.
Calciumcarbonaat - Wikipedia
Calciumcarbonaat komt in de natuur veel voor als het mineraal calciet. Het sedimentair gesteente kalksteen en de metamorfe vorm hiervan, marmer, zijn grotendeels uit calciet opgebouwd. In de natuur is calciet meestal gedeeltelijk vervuild met magnesiumionen, die in het kristalrooster van calciet calciumionen kunnen vervangen. Een instabiele polymorf van calciet is aragoniet. Van heel wat zeedieren is het skelet uit aragoniet opgebouwd. Nadat organismen met aragonietskeletten sterven sedimenteert hun skelet. Via
