“…Due to their volumes, these boulders acted as morphological highs in basinal settings, inducing geometrical and facies variations in pelagic deposits. The latter are comparable at all with those of PCP settings and are represented by the condensed-like facies mapped in the study area (Cipriani and Santantonio, 2016). These thin and fossil-rich successions accumulated in basinal settings.…”

“…This occurrence is unexpected as these deposits postdate the drowning of the local Calcare Massiccio carbonate platform, which suggests provenance from the Latium-Abruzzi Platform. This provides new evidence for restoring the Jurassic palaeogeography of Central Apennines, and for deciphering the itineraries of resedimented carbonate sands from this relatively distant source-area (Cipriani et al, 2016b). Evidence for an Early Cretaceous extensional tectonic phase, which is well-documented in the southern part of the Narni Ridge (Cipriani and Santantonio, 2014;Cipriani, 2016;Bottini, 2019a, 2019b), was also recognised in the Amelia area (Cipriani and Santantonio, 2016).…”

“…The effects of the Hettangian rifting in the Narni-Amelia Ridge are clear (see also Cipriani, 2016) and marked by facies and thickness variations of the Jurassic rocks. Lacking PCP-top condensed successions due to Mio-Pliocene tectonics and Quaternary erosion, the basin-margins analysis allowed to define the complex Jurassic palaeogeography made of several PCPs flanked by deeper basins (Cipriani and Santantonio, 2016;Cipriani, 2017). The Jurassic onlap successions display anomalous facies and thickness in respect to the classical basinal units.…”

“…The study area is dominated by Mesozoic rocks and during the fieldwork the attention was focused on them. Detailed geological mapping, facies analyses and measurement of stratigraphic sections allowed to identify several PCP-basin systems (sensu Cipriani and Santantonio, 2016;Cipriani, 2017), albeit if displaced by Neogene-Quaternary, orogenic and post-orogenic, deformations.…”

These explanatory notes are companion of a 1:12,500 geological map and present new stratigraphic and structural data gathered from the under-investigated Narni-Amelia Ridge (Central Apennines, Italy). Here Meso-Cenozoic rocks of the Umbria-Marche-Sabina sedimentary succession crop out, deeply influenced in its tectonic-stratigraphic evolution by the Early Jurassic Tethyan rifting. Geological mapping was accompanied by facies analysis and by a dense network of stratigraphic/ sedimentologic logs. Several Jurassic structural highs flanked by deeper-water basins were identified through palaeoescarpments analysis and allowed to reconstruct the Mesozoic palaeogeography of the study area. Unexpected fine-grained calcarenites made up of neritic material were found embedded in the upper Pliensbachian-Bajocian deposits (sedimented after the drowning of the Calcare Massiccio carbonate platform), providing new data for restoring the Jurassic palaeogeography of the Central Apennines. Evidence of an Early Cretaceous extensional phase, which is well-documented in the southernmost part of the Narni Ridge, was also recognised in the study area. Here the Marne a Fucoidi (Aptian-Albian) rest unconformably on the Hettangian shallow-water carbonates of the Calcare Massiccio, as a result of rejuvenation and erosion of the Early Jurassic margin of the Amelia intra-basinal high.
