“…The term "travertine", in contrast, is used for hard crystalline deposits lacking macrophytes or invertebrates that formed mainly from hydrothermal waters (Ford and Pedley, 1996;Pedley et al, 2003). If the source of CO2 dissolved in the water is used as the main criterion, the term "meteogene tufa and travertine" refers to deposits formed in COz-rich waters coming from the soil and grolll1d water, whereas the term "thermogene travertine" is used for deposits in which the waters come from the interaction of hot rock with CO2 rich fluids at depth (Pentecost, 1993;Viles and Pentecost, 2007).…”

“…Travertines precipitate in almost all climatic belts, but mostly in humid and warm climates, where high atmospheric precipitation rates recharge the groundwater circulation (Viles and Pentecost, 2007), although intensive rainfalls induce water dilution of calcium carbonate ions (Pentecost, 2005;Jones and Renaut, 2010). In arid climates, despite the reduced recharge of the aquifers, travertine precipitation may be favoured by higher evaporation rates and warmer waters (Guodie et al, 1993;Ford and Pedley, 1996;Evans, 1999;Jones and Renaut, 2010).…”

Highlights• Α facies analysis of continental carbonates and terrigenous deposits was conducted.• The interplay between hydrothermal travertines and alluvial/colluvial deposits was demonstrated.• The basin fill and depositional architecture of a continental extensional basin were studied.• Extrinsic factors controlling the evolution of the sedimentary succession were determined. ABSTRACTThe extensional Neogene Albegna Basin (Southern Tuscany, Italy) includes several thermogene travertine units dating from the Miocene to Holocene time. During the late Miocene (Messinian), a continental fault-controlled basin (of nearly 500-km 2 width) was filled by precipitated travertine and detrital terrigenous strata, characterized by a wedge-shaped geometry that thinned northward, with a maximum thickness of nearly 70 m. This mixed travertineterrigenous succession was investigated in terms of lithofacies types, depositional environment and architecture and the variety of precipitated travertine fabrics. The studied continental succession in an extensional basin provides valuable information about the interplay between thermogene travertine and alluvial/colluvial deposition, which in turn might improve the understanding of similar fault-controlled continental depositional systems in outcrops and the subsurface.

“…The IDD sometimes displays a characteristic wavelength. In the study by Viles & Pentecost (1999) IDD was found to be random, but in this case terraces were possibly initiated by large woody debris. For microterracettes, the ratio between IDD and depth is higher on gentler slopes.…”

“…The possible regular spacing between rims in the downslope direction (Fig. 9, and Hammer et al 2007; but see Pentecost 1999 andGoldenfeld 2008) may be understood in terms of this theoretical framework. However, the mechanism for lateral inhibition involves advection driven by complex hydrodynamics rather than simple isotropic diffusion, producing intricate morphologies.…”

Travertine terracing is one of the most eye-catching phenomena in limestone caves and around hydrothermal springs, but remains fairly poorly understood. The interactions between water chemistry, precipitation kinetics, topography, hydrodynamics, carbon dioxide degassing, biology, erosion and sedimentation constitute a complex, dynamic pattern formation process. The processes can be described and modeled at a range of abstraction levels. At the detailed level concerning the physical and chemical mechanisms responsible for precipitation localization at rims, a single explanation is probably insufficient. Instead, a multitude of effects are likely to contribute, of varying importance depending on scale, flux and other parameters.
