3D reconstruction of the <i>Lapis Tiburtinus</i> (Tivoli, Central Italy): The control of climatic and sea?level changes on travertine deposition

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 travertine deposition, related hydrothermal fluids rising up along discontinuities fractured carbonate bedrocks. This study presents results quarry area within tectonically Acque Albule Basin (Tivoli, Central Italy) that hosts Pleistocene Lapis Tiburtinus travertine. The reconstruction different bounding units shows complex architecture composed depressions, reliefs channels as predominant morphological elements four depositional environments (subaqueous, palustrine, slope channel). reconstructed surface maps highlight presence laterally migrating, E–W-oriented lens-shaped geometries, with drainage system persistent through time oriented towards southern part in direction Aniene River, bordering South. developed an 28 km2, accumulated sub-basins (approximately 1–2 km2 wide) subaqueous conditions interconnected hydrographic network, fluctuations River base level.
