Change from rimmed to ramp platform forced by regional and global events in the Cretaceous of the Friuli-Adriatic Platform (Southern Alps, Italy)

The Montello Thrust and the Active Mountain Front of the Eastern Southern Alps (Northeast Italy)

“…The MoA in its central part very likely formed due to buckling of the Paleocene to Miocene well-bedded interval of deep-water facies onlapping the slope of the Friuli Platform, that acted as buttress. However, it should be noted that the dip of the slope buttress, reconstructed in the cross-sections based on outcropping analogs (e.g., Picotti & Cobianchi, 2017;Picotti et al, 2019) and seismic profiles (Figure 5), is very similar to the one of the thrust reconstructed by Benedetti et al (2000). The latter authors proposed a ramp of around 45°in the upper 5 km.…”

“…All the profiles are interpolated at depth, following a mixed chrono‐lithostratigraphic subdivision of the sedimentary cover, whose thickness is inferred from wells and the outcrops of the two major Mesozoic domains, the Friuli‐Adriatic Platform, and the Belluno Basin, recently reconstructed (Picotti & Cobianchi, 2017; Picotti et al., 2019). The surface and subsurface Neogene and Quaternary stratigraphy is based on the literature and the revision of well logs available on ViDEPI (2010).…”

“…Toward the north, it merges with the BV thrust (Figure 6). The MT basal flat surface interacts with the normal fault separating the two Mesozoic domains, the Friuli Platform to the south, from the Belluno Basin north of it (e.g., Doglioni, 1992; Fantoni et al., 2002; Picotti & Cobianchi, 2017; Picotti et al., 2019). In our interpretation (section BB’, Figure 6), the footwall tip of the Mesozoic normal fault was beheaded according to the geometry and kinematics of footwall shortcuts (e.g., Cooper et al., 1989; Hayward & Graham, 1989).…”

Mid‐Cretaceous calcarenite in stone products from the Roman colony of Emona, Regio X (modern Ljubljana, Slovenia)

“…Lithostratigraphically, the Lower Cretaceous carbonates in this area belong to the Valanginian–Aptian Brje Formation, while the Povir Formation is Aptian–Cenomanian in age (Jurkovšek et al, 2013, 2016). Both formations were deposited in lagoonal environments of the shallow‐marine Adriatic Carbonate Platform (Buser, 1989; Picotti et al, 2019; Vlahović et al, 2005). Taking into consideration only the closer surroundings of Emona/Ljubljana, these two formations outcrop SW of Ljubljana between Logatec and Vrhnika (Pleničar, 1963), and SE of Ljubljana around Dobrepolje (see Figure 4b) (Buser, 1965).…”

Paleoenvironment and paleobiogeography of Lower Cretaceous carbonate successions of the northern Tethyan margin: Examples from Northeastern and Central Iran

“…Lower Cretaceous successions are distributed worldwide along the northern and southern margins of the Tethys (e.g., Kilian, 1907;Jankičević, 1978;Afshar-Harb, 1979;Föllmi et al, 1994;Dini et al, 1998;Arnaud-Vanneau, 2006;Husinec and Sokač, 2006;Velić, 2007;Sudar et al, 2008;Masse et al, 2009a;Vasković et al, 2010;Godet et al, 2010Godet et al, , 2014Morsilli et al, 2017;Schlagintweit, 2011;Stein et al, 2012;Picotti et al, 2019;Bonvallet et al, 2019;Gheiasvand et al, 2019Gheiasvand et al, , 2020; among others), the Pacific Ocean (e.g., Winterer et al, 1993;Arnaud-Vanneau and Silter, 1995;Ogg, 1995;Martin et al, 2004), and the Gulf of Mexico (e.g., González-León, 1994;Monreal and Longoria, 2000;González-León et al, 2008). These successions are usually located on the shallow-water platform and outer shelf, beyond the platform margin, and record changes of nektonic (ammonites), planktonic, and benthic organisms (e.g., foraminifera, colomiellids, rudists, calcareous algae), which are useful as biostratigraphic indicators and for environmental reconstructions.…”
