Genesis of selected Triassic basins on the Italian peninsula: Their origin and hydrocarbon potential
The paleogeographic evolution of the southern Alpine Lombardy Basin, the Central Adriatic Pescara Basin, and the Sicilian Ragusa Basin in Italy document the depositional and structural evolution of the Mesozoic Apulian Plate. These Mesozoic basins formed as a response to the Jurassic opening of the Tethyan Ocean. Due to their respective position in relation to the Mesozoic Tethyan spreading center, each of the three basins formed with unique structural entities. The Mesozoic paleogeographic history of the Lombardy Basin suggests that it initially formed a continental arc basin on the northern margin of the Apulian Plate. As Tethyan rifting progressed, the basin subsequently evolved into an Early Jurassic passive continental rift margin. The Pescara Basin, with its central Apulian paleogeographic location, developed as a Tethyan rift basin in the Jurassic. The Ragusa Basin represents Mesozoic developments along the southern portion of the Apulian Plate. Depositionally, paleohighs and periods of tectonic stability are typically represented by extensive carbonate platform deposits. Within these carbonate platforms incipient stages of faulting are characterized by shallow anoxic lagoonal deposits. These structurally weak ones were subsequently incorporated within the Tethyan Jurassic rift. Synrift deposits are predominantly characterized by thick sequences of Jurassic and Cretaceous pelagic carbonates.
