Calcium Carbonate: A Mineral in Your Daily Life

Natural Calcium Carbonate is also known as Calcite. It is a rock-forming mineral with a chemical formula of CaCO3 . It is extremely common and found throughout the world insedimentary,metamorphic, andigneous rocks.

Calcite is the principal comprise oflimestone andmarble. The properties of calcite make it one of the most used minerals. It has more uses than almost any other mineral.

Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell

Calcite as Limestone and Marble

Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis. Limestone also forms as a deposit in caves from the precipitation of calcium carbonate.

Marble is a metamorphic rock that forms when limestone is subjected to heat and pressure. A close examination of a broken piece of marble will usually reveal obvious cleavage faces of calcite. The size of the calcite crystals is determined by the level of metamorphism. Marble that has been subjected to higher levels of metamorphism will generally have larger calcite crystals.
