Groundwater sustainable yield is a concept widely treated theoretically in the literature. Moving from theoretical concepts to definition of practical measures for groundwater management not easy due site-specific characteristics system. This study aimed at identifying which factors influence plain Tivoli (Central Italy), where thermal springs with considerable flow (over 2 m3/s) emerge (or rat...

3D modelling is a fundamental tool to visualize and understand the history of sedimentary basin filling reconstruct geobody architecture. Spatial distribution discontinuity surfaces characteristics provide valuable information on factors controlling evolution basins. Several Neogene-Quaternary basins central-western Italy are controlled by extensional strike-slip tectonics characterized travert...

The Acque Albule Basin in Tivoli (Rome, Central Italy) represents one of the largest exposures travertine deposits world. A detailed study Upper Pleistocene Testina travertine, constituting poorly lithified top part Lapis Tiburtinus travertines, is presented. Fieldwork performed an area 10 km2 and petrographic analysis allow recognition six geobodies with different geometries, degree diagenetic...

A travertine specimen collected from the western part of Yunnan Province of China was subjected to microstructural analysis by powder X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy and energy dispersive X-ray spectroscopy. A new formation mechanism was proposed whereby polycrystalline rhombohedral particles of magnesium-containing calcite under...

Ancient historical references consistently describe an intoxicating gas, produced by a cavern in the ground, as the source of the power at the oracle of Delphi. These ancient writings are supported by a series of associated geological findings. Chemical analysis of the spring waters and travertine deposits at the site show these gases to be the light hydrocarbon gases methane, ethane, and ethyl...
