Marble: Metamorphic Rock: Pictures, Definition, Properties

FormationResourcesUsesAppearanceReactionsPropertiesAdvantagesNomenclatureMarble 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 (CaCO3) 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 form a rock that is a mass of interlocking calcite crystals. A related rock在geology上查看更多信息
