Marble is a composition formed through the recrystallization of limestone and dolomitic limestone as a result of the process of metamorphism. 90-98% of the composition consists of CaCO3 (calcium carbonate). It contains a low percentage of MgCO3 (Magnesium carbonate). In marbles composed of CaCO3 crystals, the primary mineral is “Calcite”. They may also contain small amounts of silicon, silicon dioxide, feldspar, iron oxide, mica, fluorine, and organic matter. Their colors are usually white and grayish. However, due to foreign substances, it can also exhibit colors such as yellow, pink, red, bluish, brownish, and black. When examined under a microscope, it is observed to consist of well-interlocked “Calcite Crystals”.
