Calcite limestone.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone ... Limestone is a sedimentary rock having more than 50% calcium carbonate in the form of calcite by weight. It also contains some percentage of other materials as well. The chemical composition of pure calcite is CaCO3.
