amq-341	Gandin, Anna; Capezzuoli, Enrico	Travertine versus Calcareous tufa: distinctive petrologic features and stable isotopes signatures	2008	12	.pdf	application/pdf	9132	422	50	Terrestrial limestones, mainly deposited as calcite crusts by carbonate-rich waters flowing in subaerial settings, originate from warm- to-hot waters of hydrothermal provenance (travertines) or from cool waters of karstic derivation (calcareous tufa). The detailed analysis of the lithofacies of calcareous tufa and travertines as well as the critical elaboration of existing geochemical data, shows that the petrologic features and stable isotopic signatures reflect the contrasting environmental conditions of deposition deriving from physico-chemical properties of the feeding waters that, although mostly of meteoric provenance, experienced different circulation/recharge history.	cache/amq-341.pdf	txt/amq-341.txt
