7.2: Classification of Metamorphic Rocks
Marble is metamorphosed limestone. When it forms, the calcite crystals tend to grow larger, and any sedimentary textures and fossils that might have been present are destroyed. If the original limestone was pure calcite, then the marble will likely be white (as in Figure (PageIndex{6})), but if it had various impurities, such as clay, silica ...
