The Jurassic sequences of the northern and central Apennines were deposited along the margin of the oceanic Tethys. The most important features of this margin during the Jurassic include: 1) the development of Bahamian-type carbonate platforms (Latium-Abruzzil with adjacent belts of turbiditic carbonate sedimentation; 2) a sequence of pelagic sediments in the starved distal continental margin whose facies was mainly determined by synsedimentary faulting, prolonged subsidence and increasing water depth (Tuscany, Umbria-Marchel, and 3) the accretion of oceanic crust and deposition of oceanic sediments in the Ligurian zone. The paleotectonic and sedimentary evolution of the Umbrian and Tuscan zones can be best compared to that of starved continental margins of Atlantic-type.

Abstract
The Jurassic sequences of the northern and central Apennines were deposited along the margin of the oceanic Tethys. The most important features of this margin during the Jurassic include: 1) the development of Bahamian-type carbonate platforms (Latium-Abruzzil with adjacent belts of turbiditic carbonate sedimentation; 2) a sequence of pelagic sediments in the starved distal continental margin whose facies was mainly determined by synsedimentary faulting, prolonged subsidence and increasing water depth (Tuscany, Umbria-Marchel, and 3) the accretion of oceanic crust and deposition of oceanic sediments in the Ligurian zone. The paleotectonic and sedimentary evolution of the Umbrian and Tuscan zones can be best compared to that of starved continental margins of Atlantic-type.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
