travertine
travertine , form of massive calcium carbonate, CaCO 3 , resulting from deposition by springs or rivers. It is often beautifully colored and banded as a result of the presence of iron compounds or other (e.g., organic) impurities. This material is variously known as calc-sinter and calcareous tufa and (when used for decorative purposes) as onyx marble, Mexican onyx, and Egyptian or Oriental alabaster. Travertine is generally less coarse-grained and takes a higher polish than stalactite and stalagmite, which are similar in chemical composition and origin. |

travertine
travertine. A limestone of almost pure calcium carbonate found at Tivoli (Latin Tibur, hence lapis Tiburtinus—Tiburtine stone) and elsewhere in Italy. Varying in colour from pale buff to orange pink, it is sometimes porous. It has been much used in the buildings of Rome (notably the Colosseum and the colonnade of St Peter's) and has also been employed for outdoor sculpture that does not require a smooth finish, as for example by Bernini in his Triton Fountain in Rome (1642–3).

travertine
travertine Calcium carbonate deposited by precipitation from carbonate-saturated waters, particularly from hot springs. Travertine deposits are sometimes massive, but often display a concentric or fibrous internal structure, sometimes building large, concentric, spherical masses. Travertine is also found in cave deposits in the form of stalagmites and stalactites. A porous, sponge-textured form of travertine is referred to as ‘tufa’ or ‘calc-sinter’.
