Influence of the Plio-Pleistocene tectonics on the evolution of the Purgatorio polje (north-western Sicily)
The evolution of large landforms such as polje are related in most cases to geological events affecting a specific areal context and/or to climatic events which, in combination with the tectonics, affect the karst base level, in a more or less pronounced manner depending on the proximity of limestone karst mountains to the coastline. The genesis of these aforementioned forms depends primarily on structural and lithological factors, their evolution is instead controlled by tectonic and climaticeustatic factors in the reliefs close to the coast. In the inland, due to the distance from the coast, the effects of the latter factors on the karstification process could be less, or very bland, in r…
Flank Margin Caves In Telogenetic Limestones In Italy
Almost 20% of Italy is characterized by the outcropping of carbonate massifs ranging in age from Cambrian to Quaternary. Coastal karst is present in many Italian regions: from North-East to South and West: the Gulf of Trieste, the Conero (South of Ancona, Marche), the Adriatic coast of Apulia including Gargano, Murge and Salento, Maratea in Basilicata, Cilento in Campania, Circeo and Gaeta in Latium, Argentario and Giannutri Island in Tuscany, the southernmost part of the Ligurian Alps, Palermo Mts., San Vito Lo Capo, Syracuse coast and Marettimo Island in Sicily, and, especially, in Sardinia, which has carbonate rocks touching the sea along the coast of Balai near Porto Torres, Capo Caccia…
