trav·er·tine

T0331000 (trăv′ər-tēn′, -tĭn)n.1. A light-colored porous calcite, CaCO₃, deposited from solution in ground or surface waters and forming, among other deposits, stalactites and stalagmites.2. A compact calcium carbonate used as a facing material in construction.

[French, from Italian travertino, alteration of tivertino, from Latin (lapis) tīburtīnus, (stone) of Tibur (Tivoli), an ancient city of central Italy.]

travertine

(ˈtrævətɪn) or

travertin

n (Minerals) a porous rock consisting of calcium carbonate, used for building. Also called: calc-sinter [C18: from Italian travertino (influenced by tra- trans-), from Latin lapis Tīburtīnus Tiburtine stone, from Tīburs the district around Tibur (now Tivoli)]

trav•er•tine

(ˈtræv ərˌtin, -tɪn)

n. a form of limestone deposited by springs, esp. hot springs, used in Italy for building. [1545–55; < Italian travertino, early also trevertino, (marmo) tibertino < Latin Tīburtīnus=Tīburt-, s. of Tīburs Tibur (see Tivoli) + -īnus -ine¹]

travertine

Calcium carbonate deposited by water, as in stalactites.

travertine

(trăv`ərtĭn, –tēn), form of massive calcium carbonate, CaCO₃, 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

A variety of limestone deposited by springs, usually banded, commonly coarse and cellular, often containing fossils; used as building stones, especially for interior facing or flooring. See also: stone
