I sistemi carbonatici giurassici della Sardegna orientale (Golfo di Orosei) ed eventi deposizionali nel sistema carbonatico giurassico-cretacico della Nurra (Sardegna nord-occidentale)

This field trip gives a panoramic of the facies association and sedimentological-stratigraphic evolution of
Jurassic-Cretaceous depositional systems of eastern (Golfo di Orosei) and western (Nurra) Sardinia. Carbonate
deposition in western Sardinia occurred in an epeiric sea during Jurassic and Cretaceous whereas carbonates
of the eastern Sardinia figure out a complex depositional settings with intraplatformal basins facing the Alpine
Tethys from a basal transgression in the Bajocian to Berriasian. The presence of partly coeval succession allows
a comparison between these two depositional systems and highlights relation with global and regional events.
The Jurassic-Cretaceous carbonate succession of Sardinia shows similarities with coeval succession of the
Provencal-Pyrenean domain (Nurra), nevertheless differences, both in terms of facies characters and distribution
and range of stratigraphic gaps, occur between the successions of eastern Sardinia. These differences can
be ascribed to different paleogeographic and depositional settings.
