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 recrystallizes to Marble: Metamorphic Rock: Pictures, Definition, Properties
