Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble usually lays among the oldest part of the.
Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
