“…Well data and seismic facies analysis from 2D seismic reflection data in the Barreirinhas, Ceará and Potiguar Basins resulted in at least five chronostratigraphic‐tied seismic horizons interpreted across the BEM (Figures 4 and 5). The subsidence histories of the Barreirinhas, Ceará and Potiguar Basins were calculated by backstripping the mapped BEM stratigraphy following well‐known methodologies (Basilone, 2022; Dressel et al, 2015; Matenco et al, 2003; McKenzie, 1978; Steckler & Watts, 1978; Van Hinte, 1978; Wagreich & Schmid, 2002; Xie & Heller, 2009). First, check‐shot (time‐depth) data were extracted from well reports and used to constrain the compaction of stratigraphy as a function of depth for each basin.…”

Stratigraphy along the Brazilian Equatorial Margin is a crucial guide to the geodynamic history of rifting of Pangea and formation of the South Atlantic Ocean. Understanding the evolution of the Brazilian Equatorial Margin, which intersects the Saint Paul and Romanche Fracture Zones on the western margin of South Atlantic Ocean, is also key for reconstructing eustatic histories and natural resource exploration. In this study, we quantify the stratigraphic and subsidence histories of three sedimentary basins—Barreirinhas, Ceará, Potiguar—that sit within the margin. Stratigraphy was mapped using ca. 900‐line‐km of two‐dimensional seismic data. Biostratigraphic and check‐shot data from 23 wells drilled on the continental shelf, slope and in the distal parts of these basins were used to date and depth‐convert stratigraphy. Check‐shot data were also used to parameterise compaction. The mapped stratigraphy was backstripped to calculate subsidence histories for the basins. Subsidence curves were decompacted, water‐loaded and corrected for palaeo‐water depths using biostratigraphic data from well reports. The mapped stratigraphy of the Barreirinhas and Ceará Basins and theoretical subsidence curves indicate that stretching factors did not exceed 1.6. These values suggest that these basins can be regarded as failed rifts. In contrast, more distal stratigraphy mapped in the Potiguar Basin to the south indicates that it stretched by a factor of 5–6. Calculated subsidence histories indicate that this basin formed primarily because of Cretaceous rifting and Cretaceous to Recent post‐rift thermal sag, with amplitudes governed by the amount of initial stretching.

“…During the Middle-Late Norian the Dolomia Principale/Hauptdolomit platform records, in the Central Austroalpine and parts of the Southern Alps, a major tectonic event responsible for the development of rapidly-subsiding, fault-controlled, confined, intraplatform basins (Bechst€ adt et al, 1978;Jadoul, 1985;Jadoul et al, 1992;Berra, 1995;Berra & Jadoul, 1996;Berra & Jadoul, 1999;Cozzi, 2002;Berra et al, 2010). Syndepositional tectonics is documented by major facies and thickness changes of the Norian succession, that increase from a few hundreds of metres in lowsubsiding domains (for example, Dolomites) to more than 2 km in fault-controlled intraplatform troughs.…”

“…Basinal areas are documented in the Central Southern Alps (Lombardy Basin; Jadoul, 1985; Jadoul et al ., 1992; Berra, 1995; Trombetta & Claps, 1995; Berra & Jadoul, 1996; Berra & Jadoul, 1999; Berra et al ., 2010; Fig. 1), in the Eastern Southern Alps (Carnia; Cozzi, 2002), in the Central Austroalpine (Ortles and Quattervals Nappes; Berra, 1995; Berra & Jadoul, 1999), in the Northern Calcareous Alps (Seefeld Basin; Fruth & Scherreiks, 1984), in the Apennines (Cirilli et al ., 1999; Zamparelli et al ., 1999) and in Sicily (Basilone, 2022, and references therein). Sedimentation in the fault‐controlled intraplatform basins is mainly characterized by dark, bedded resedimented limestones and scarp breccias (Jadoul, 1985), fed by the Dolomia Principale highs.…”

Identification of the processes producing soft‐sediment deformation structures, common in siliciclastic deposits and less abundant in carbonate successions, is complex, because different processes may produce similar structures. Thus, interpreting the origin of these structures may be challenging: it requires both a detailed sedimentological study and the knowledge of the depositional environment and stratigraphic evolution, in order to provide hints to identify the processes affecting sediments after deposition. Among the potential causes of the formation of soft‐sediment deformation structures, seismic shock is one of the possibilities, but their origin could be also related to other triggering mechanisms, such as volcanic activity, sediment loading, salt tectonics, fluid expulsion, meteorite impacts and mass movements. Although it is a plausible option, the interpretation of these structures as ‘seismites’ is not obvious: it must be supported by different lines of evidence, considering that the correct interpretation of soft‐sediment deformation structures as a consequence of seismic shocks acquires important implications in palaeoseismology studies.The occurrence of diverse soft‐sediment deformation structures in a fault‐controlled basin (i.e. in a geological setting characterized by syndepositional tectonics) preserved in different subenvironments of a Norian carbonate system in the Southern Alps of Italy provides the chance to characterize different types of soft‐sediment deformation structures along a platform‐to‐basin depositional profile. Presence of pseudonodules in basinal resedimented limestone, sedimentary dykes and clinostratified breccias with unlithified clasts in slope settings and liquefaction of inner platform facies at the platform top testify to an origin compatible with multiple seismic shocks, repetitively affecting the same stratigraphic intervals. The diverse types of soft‐sediment deformation structures in the studied carbonate system provide a rich catalogue of structures related to seismic shocks, representing a possible reference for other similar settings.
