Upper Silurian, Lower and Upper Devonian conodonts are discovered for the first time from rare calcareous beds of the Serra S'llixi Group in the Pala Manna area, in connection with the nucleus of the "Sarrabus syncline" (southeastern Sardinia) where

The activity of the first Hercynian tectonic phase is documented in the Lake Mulargia area (central Sardinia) by the presence of numerous tectonic units. We have examined in particular the southern region of the lake, where one of the upper tectonic

The subject of this paper is new geological and stratigraphical data regarding the Paleozoic in the Sarrabus area (Southeastern Sardinia). More particularly Tremadocian (Lower Ordovician) acritarchs have been found in samples taken for microfossils r

Twenty-two conodont species are recognized in the Ockerkalk exposed in the Silius area (Gerrei, southeastern Sardinia). The fauna, which is the first reported from this peculiar facies, indicates a Ludlow and e.-m. Pridoli age for this limestone. Thr

This review illustrates the most important features of the Ordovician successions of the Sardinian basement. We focus on the stratigraphy and tectonic structures in the tectonic units of the External and Nappe zones of the Variscan basement. The Ordo

In SW Sardinia, the continental Tertiary successions referred up to now to the Cixerri Fm. (Middle Eocene–Lower Oligocene?) have been investigated. Sedimentological analysis suggests these deposits lied down in fluvial environments and comprised be

In eastern Sardinia, the first Jurassic sedimentary cycle (Bajocian–Kimmeridgian) develops in response to the opening of the Alpine Tethys Ocean. Starting during the Bajocian (Middle Jurassic), over a horst-and-graben system initially drowning to t
