Geoarchaeology of "anthropogenic" travertine: a story of water and life etched in stone

subject

description

The notion of “anthropogenic” carbonate deposits takes into consideration human impact on continental limestones precipitated from hot (travertine) or cold (calcareous tufas, speleothems) waters. It is documented here by a geoarchaeological study of the Roman site of Jebel Oust, Tunisia, where the exploitation of a hot spring is attested from the first century AD to the end of Late Antiquity. Petrographical and geochemical analyses performed on travertine deposits offer evidence of the anthropisation of the hot spring and its associated deposits, and reveal new elements of water management and bathing practices during Roman times.
