  • Marble Encyclopedia

    Marble. Marble is metamorphosed limestone that is limestone that has been melted and allowed to resolidify.If the original limestone is a calcite limestone then the marble is a calcite marble (i.e. mostly CaCO 3) if the original limestone is a dolomitic limestone then the marble is a dolomitic or magnesian marble (i.e. mostly CaMg (CO 3) 2) nongeological contexts the term marble is
