“…This knowledge is potentially valuable for quantitative methods such as studies that employ numerical simulation of sedimentary processes (Faria et al, 2017;Huang et al, 2015) or investigate orbital cycles to calibrate stratigraphic time scales (Hilgen et al, 2015;Hinnov, 2018). In the oil industry, for instance, it is used to estimate the vertical recurrence of stratigraphic units (Magalhães et al, 2020;Melo et al, 2020Melo et al, , 2021.…”

Multi‐scale transgressive–regressive cycles from the mid‐Jurassic were recognised in the Central Lusitanian Basin, Portugal. These cycles allow the depositional evolution of the basin to be better understood and aid in the construction of stratigraphic sequences composed of three hierarchies. The stacking pattern of high‐frequency transgressive–regressive sequences forms larger clusters that define medium‐frequency transgressive–regressive sequences. Likewise, the stacking pattern of medium‐frequency transgressive–regressive sequences generates two Bathonian–early Callovian low‐frequency transgressive–regressive sequences. Integration of several methods supported the interpretation of facies associations representing clastic deposition in offshore to shoreface environments and carbonate sediments in outer to inner ramp settings. New data from calcareous nannofossils and dinoflagellate assemblages constrained the interval's Bathonian–early Callovian age, thus unveiling the Middle–Upper Jurassic disconformity and filling the Middle Jurassic stratigraphic record gap in the Central Lusitanian Basin. This study may be helpful for similar successions in Tethyan domains and comparable depositional settings elsewhere.

“…[25][26][27] The Potiguar Basin is located on the easternmost section of the Brazilian equatorial margin and extends from onshore to offshore. 39 Both the Potiguar Basin and the Paraná Basin were classified as highly prospective for storage by Ketzer et al, 25 in an assessment of all Brazilian sedimentary basins taking into account criteria such as emission sources, hydrocarbon production, occurrence of coal, saline formations, and infrastructure. Both basins' potential for CCS was also assessed through CO 2 capture from biomass sources with a focus on bioethanol production facilities.…”

This study underscores the critical role of carbon capture and storage (CCS) in mitigating greenhouse gas emissions and addresses the potential for CCS projects in saline aquifers in Brazil, one of the world's largest carbon emitters. The country's ability to adopt CCS is significantly influenced by the availability of data related to regional CO2 storage potential and identifying suitable geological framework for CO2 injection. While oil and gas reservoirs have traditionally been prioritized, saline aquifers represent an underexplored and potentially higher capacity storage option. Despite Brazil's 31 sedimentary basins, the data quantity and availability for these contexts remain insufficient for advanced studies on the geological storage of CO2 considering saline aquifers. An initial study was conducted indicating five potential targets in the Paraná and Potiguar Basins for geological storage in saline aquifers based on available public data, mainly drilling data. This review reveals substantial challenges related to the evaluation of Brazil's CO2 storage capacity, such as the lack of modern seismic studies, the absence of a regulatory framework for CO2 storage, and insufficient investment in new well exploration. These challenges necessitate multistakeholder collaboration, the development of a supportive regulatory environment, and investment in extensive site characterization campaigns. Addressing these barriers is fundamental to realizing the country's CCS potential and contributing to global decarbonization efforts. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Three types of stratigraphic surfaces used in marine areas can be applied to continental deposits (Hanneman & Wideman, 2010): subaerial unconformities, correlative conformities and maximum flooding surfaces. Units are bounded by sequence boundaries (subaerial unconformities and their correlative conformities), which represent the shallowest environment recorded within a sequence and coincide with shifts in stacking patterns between shallowing‐upward and deepening‐upward trends (Strecker et al., 1999; Changsong et al., 2001; Keighley et al., 2003; Hanneman & Wideman, 2010; Pérez‐Rivaréz et al., 2018; Deschamps et al., 2020; Guan et al., 2021; Melo et al., 2021; Lettéron et al., 2022). Subaerial unconformities were identified by surfaces characterised by features such as erosion karstification or palaeosoils occurrence—whereas correlative conformities are surfaces that were not (Hanneman & Wideman, 2010).…”

The difficulty of correlating continental deposits hinders predicting lacustrine and palustrine carbonate facies variations in time and space. This study aims to understand better the factors governing these facies heterogeneities by measuring carbonate isotopes and conducting facies, petrographic and sequence stratigraphic analyses of the Lutetian–Aquitanian deposits of the Paris Basin, that record the transition from marine to lacustrine environments. Large‐scale correlations enabled the definition of two lacustrine–palustrine carbonate facies models. (1) The coastal lacustrine system (Bartonian to Rupelian), consists of fine‐grained brackish carbonate exhibiting episodic marine inputs during short‐term relative sea‐level maxima and evaporite sedimentation during relative sea‐level minima. Lacustrine sediments differ notably from marine ones with more negative δ13C and δ18O compositions that co‐vary and a biota adapted to low salinity conditions. In the associated palustrine environment, depositional sequences evolve upwards from micritic lacustrine deposits to nodular and then laminar calcretes. Microbial‐coated grains and rhizoliths indicate biological processes during repeated subaerial exposure phases in sub‐tropical to arid climates. (2) The inland lacustrine system (Rupelian and Aquitanian) was disconnected from the marine domain and showed evidence of microbial activity with microbial crusts and oncoidal rudstones. Facies rich in micritic intraclasts composed of palustrine and lacustrine facies indicate the reworking of already lithified sediments along the margins. In the palustrine domain, the calcrete facies are less abundant than breccias formed in‐situ by desiccation, limestones with root traces, or organic‐rich wackestones and marls. This system reflects a more temperate climate with more developed microbial structures and less exposed carbonates than the coastal lacustrine system. The southward migration of the depocentre and the transition from marine environments to (1) coastal and then (2) inland systems are controlled by uplift phases induced by Pyrenean and Alpine orogenesis. Third‐order relative sea‐level variations appear to control only short‐term cycles in coastal systems.
