    Limestone—A Crucial and Versatile Industrial Mineral Commodity

    This process is called “metamorphism.” There are also rare “igneous” carbonate rocks that have crystallized from molten magma in the same way that lavas or granites have. These are called “carbonatites,” and this rock type is mined at a few places in the world as industrial limestone. Sedimentary limestone deposits can be extensive, covering hundreds . of square miles, and can be
