Limestone And Marble Are Composed Chiefly Of The Mineral
Marble is composed chiefly of mineral Calcite CaCO 3 in its recrystallised form Small amounts of many other granular minerals like olivine serpentine garnet and some amphiboles are also present in many varieties which are derived from the impurities present in the original limestone during the process of metamorphic recrystallisation
