The Tiber Valley (Valle del Tevere (Italian))is the largest geographical part of the Tiber basin[1] of the Tiber river included in the Emilia-Romagna, Tuscany, Umbria, and the Lazio regions; it is characterized by river terraces and floodplain areas that extend from the Apennine belt up to the delta of the Tiber river in the Lazio coast of the Tyrrhenian Sea.
Geology
[edit]The Tiber basin is made up of four main morpho-structural environments:[2]
- the upper Tiber basin, composed mainly of terrigenous sediment in flysch facies of Tuscan origin (on the right bank north of Lake Trasimeno) and Umbria-Marche (on the left bank)
- the Apennine carbonate ridge, which occupies the eastern and southern sector, made up of carbonate reliefs;
- the Tiber graben with its marine to continental facies deposits, the intermountain basins;
- the volcanic systems of the Volsini Mountains, Cimini, Sabatini and Alban Hills, which occupy the southwestern sector.
- Paleotevere Graben[3]
- Paglia-Tevere Graben[4]
- Tiber Graben (Chiana Valley)[5][6]
