Pure white marble is the result of metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone.Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite rock. Metamorphism causes variable recrystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
The prized yield from Carrara quarries through millennia has been Statuario, a pure white marble (coloring in other marbles arises from intermixture with other minerals present in the limestone as it is converted to marble by heat or pressure). However, by the end of the 20th century, the known deposits of Statuario near Carrara are played out. The quarries continue to remove and ship up to a million tons/year of less-esteemed marble, mostly for export.
Bianco Carrara classified in C and CD variations as well as well as Bianco Venatino and Stauarietto are by far the most common types with more expensive exotic variations such as Calacatta Gold, Calacatta Borghini, Arabescato Cervaiole and Arabescato Vagli quarried throughout the Carrara area.
