Travertine (limestone) dams are common in caves [1], springs [2], [3], [4] and rivers [5], [6] worldwide, and represent one of the most striking examples of geological pattern formation on the Earth's surface (for simplicity, we use the term travertine rather than tufa also for cold-water deposits, see [7]).Our geomorphological terms follow [8].The …

A stratigraphy of a buried travertine deposit was developed using stable isotope geochemistry, trace elements, and radiometric dating. The travertine was identified in a well at Prima Porta (north of Rome, Italy), located at the western boundary of the Tiber Valley, a morpho-tectonic depression of extensional origin. It deposited close to a spring …

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.

Travertine is used as flooring and covering stone with a polished finish. It can be recognized as its banded but rather holey structure. As a result of cutting the travertine in two directions, two surface appearances appear, the vein-cut look and the cross-cut look (Fig. 1, Fig. 2).The most known and common cutting type of travertine stone is "vein cut."
