The Aurunci Mountains (Italian Monti Aurunci) is mountain range of southern Lazio, in central Italy. They are part of the Antiappennini, a group running from the Apennines chain to the Tyrrhenian Sea, where they form the promontory of Gaeta. They are bounded northwestward by the Ausoni Mountains, northward by the Liri river, eastward by the Ausente, southeastward by the Garigliano and southward by the Tyrrhenian sea. The line between the Aurunci and the Ausoni has not been clearly established but the Aurunci are considered by convention to be east of a line through Fondi, Lenola, Pico, S.Giovanni and Incarico.[1] Altitudes vary from hills to the 1,533 m of Monte Petrella. Main peaks include the Redentore (1,252 m) and Monte Sant'Angelo (1,402 m). They include a Regional Park, the Parco Naturale dei Monti Aurunci, created in 1997.
The mountains take the name from the ancient tribe of the Aurunci, an offshoot of the Ausoni. Both tribes were derived from the Italic people who were called by the Romans the Volsci; hence, the Monti Lepini, the Monti Ausoni and the Monti Aurunci are also called the Volsci or Volscian Chain.[2] Coincidentally they are all of the same karst topography and have the same orogeny, which is not quite the same as the Apennines proper.
The Monti Aurunci mainly consist of friable limestone, which becomes harder toward Gaeta. The degree of faulting and cracking is so high that the mountains retain no rainfall; it sinks in to emerge as springs (and in human times wells) on the lower flanks. The stream beds are dry except for vernal pools.
Most generally, the western central coastal region of Italy is the front of a subduction zone where the African plate moving locally from southwest to northeast is carried under the European plate. There is some counterclockwise rotation of Italy; hence the faults in the Tyrrhenian Sea slip both parallel to the shoreline and perpendicular to it.
The surface rock in the Anti-Apennines was deposited on the floor of Tethys Sea during the Jurassic and Cretaceous of the Mesozoic. This lighter calcareous rock rides over the front of the subduction zone, uplifted by compressional and isostatic forces. Just behind it is a zone of crustal thinning caused by extensional forces; i.e., the subduction and the rotation cause a wave of compression with a peak under the Anti-Apennines and a valley in the Tyrrhenian Sea. The result is a karst-graben or half-graben landform with the Volscian Mountains as karst and the coastal chain of Pontine marshes, South Pontine marsh, Terracina Basin, Gaeta Basin and Volturno Basin as graben.
This landform began to appear in the Messinian stage of the Miocene, about 7.2 to 5.3 million years ago. It went on to mature in the Pliocene. Also in this time volcanic activity associated with the faults and the weakening of the crust over the subduction created the volcanic zones of Latium and Campania, which intruded into the karst-graben, mainly on the karst side. In the Pleistocene the basins slowly filled with sediment from the weak run-off of the mountains, accelerating with the deforestation of modern times.
I Monti Aurunci sono un gruppo montuoso dell'Italia centrale, appartenente all'Antiappennino laziale, contenuto interamente nel Lazio. Confinano a nord con il gruppo dei Monti Ausoni nella linea congiungente Fondi-Lenola-Pico-Ceprano, a est spingendosi in prossimità della Valle del Liri, a sud con il fiume Garigliano mentre ad ovest sono limitati dal mar Tirreno, con le estreme propaggini del Monte Lauzo.
La collocazione di questa catena montuosa del Lazio meridionale, è da individuarsi quindi fra il corso del Liri-Garigliano, il Mar Tirreno e il contiguo massiccio dei Monti Ausoni.
I Monti Aurunci sono un'area tutelata con l'istituzione del Parco Naturale Regionale dei Monti Aurunci. Ad est del passo di S. Nicola, che mette in comunicazione il territorio di Itri con quello di Campodimele, si estende la gran parte del massiccio.
Esso è costituito da più catene parallele sviluppate lungo l'asse nord-sud, in cui si possono identificare due dorsali principali: quella orientale, dal M. Fammera al M. S. Angelo, e un'altra più occidentale, che si sviluppa dal M. Faggeto al M. Orso. Ancora più ad ovest il gruppo viene chiuso da una terza catena, compresa fra la valle di Itri e la piana di Fondi, che è composta da cime meno elevate, fra cui (da nord a sud) il Monte Le Vele, Montefusco (sulla cui sommità è arroccato il santuario della Madonna nera della Civita) ed il M. Grande.
Al di là di questa zona centrale, il resto del territorio è costellato di cime minori ed isolate, come il Monte Lauzo, che si eleva al di sopra di Sperlonga, ed il M. Maio, situato quasi al confine con la Campania, fra il fiume Ausente ed il Garigliano.
