Elemental and Sr–Nd isotopic evidence for unravelling the origin of the low-temperature geothermal fluids of Tivoli Terme (Latium, central Italy) between erosional S4 and S3 phases (upper Pleistocene) and neotectonics implications

Using stable isotopes in deciphering climate changes from travertine deposits: the case of the Lapis Tiburtinus succession (Acque Albule Basin, Tivoli, Central Italy)

“…Nevertheless, the hydrothermal origin of the travertines obviously masks the precise water temperature changes related to climatic shifts, as compared to the marine limestones usually investigated in this context. However, a potential climatic control, among the endogenic ones, on the travertine deposition has already been found by different studies and based on sedimentological organization and stable isotope values (Faccenna et al, 2008;Anzalone et al, 2017;Castorina et al, 2023). As already found by Dabkowski and Limondin-Lozouet (2022) and by Sancho et al (2015), the calcareous tufa deposits are able to record climatic conditions, especially during the Holocene and Pleistocene.…”

“…Travertine deposition can be influenced by global changes in climate (Ricketts et al, 2019). However, despite the singular attempt by Ricketts et al (2019) to correlate the oxygen isotope record of travertine to global trends, no other studies have investigated the potential of travertine systems to record climate changes since most of the abundant literature focuses on the endogenic causes leading to travertine deposition (Crossey et al, 2006;Uysal et al, 2007Uysal et al, , 2009Brogi et al, 2010;Faccenna et al, 2008;De Filippis et al, 2013;Castorina et al, 2023) than on external forcing (Frank et al, 2000;Mancini et al, 2021).…”
