Characteristics and use
Roman travertine is a calcareous sedimentary rock; it owes its genesis to the aggregation of deposits of various kinds at a certain depth of the earth’s crust. In sedimentary rocks you can often find fossils of animals or plants that are incorporated into the sediment that forms the rock.
The sedimentary deposits originate from the disintegration of pre-existing rocks, mainly due to the action of atmospheric agents. The disintegrated particles can be transported in the water, both in suspension and in solution. In the latter case they will form deposits of chemical origin.
Finally, travertine is used both indoors and outdoors for walls, claddings, floors, string courses, curbs and other architectural and design elements; it is also used for sculpture. Italian travertine are quarried in the district of Tivoli-Guidonia in the province of Rome (Roman travertine) and in the provinces of Siena (Rapolano travertine), Ascoli Piceno, Grosseto, Viterbo.
