Travertine is a sedimentary rock formed in a continental environment by the precipitation of crystals of calcium carbonate (CaCO3). In a subaerial environment and in proximity to a permanent source, the precipitation of calcite, according to the reaction – Ca(HCO3)2 --> CaCO3 + H2O + CO2 – creates deposits assisted by the reaction of film algae and bryophytes.
