... Limited halite and the presence of continuous carbonates implies marginal Zechstein facies in a predominantly platform-slope environment (Smith 1989;Tucker 1991). This is further supported by the presence of thick Z1 Hayton Anhydrite confirming the onshore extension of the Z1 Werraanhydrit Platform (Garland et al. 2023;Houghton et al. 2024). Thickening of the Z1 Cadeby Formation towards well Whenby-1 suggests more platform-associated facies towards the west which is consistent with published Z1 paleogeographical models (Smith 1989;Fyfe and Underhill 2023a, b). ...

... Noteworthily, components of the ZSG were repeatedly remobilised throughout the Mesozoic and Cenozoic to form complex salt structures (van Hoorn, 1987;Stewart and Coward, 1995;Geluk, 1999;Underhill, 2003;Peryt et al., 2010;Pharaoh et al., 2010;Grant et al., 2019), which controlled later structural (halokinetic) styles and depositional patterns across a vast portion of the SPB (van Hoorn, 1987;Stewart and Coward, 1995;Stewart, 1996;Stewart, 2007). For these specific reasons, the ZSG of the Southern North Sea has attracted particular scientific attention for carbon storage purposes (Underhill et al., 2009;Brackenridge et al., 2023;Sutton et al., 2024). ...

... Second, VFTs offer autonomy in terms of spatial and temporal access, freeing students and teachers from external environmental factors (Boyle et al., 2007;Pugsley et al., 2021). Within VLEs, students can move freely, which is especially advantageous for those with physical difficulties, enhancing accessibility (Elleven et al., 2006). ...

... Generating synthetic geomechanical logs (Eshkalak et al. 2013;Li et al. 2018;He and Misra 2019), reservoir characterization from performance data (Kulga et al. 2018), rock classification (Ahmadov and Ruse 2022), and petrophysical and geochemical characterization (Xu et al. 2023) are among the example applications for the characterization of shale and tight reservoirs. Physical modeling of logging tools, well and reservoir surveillance, automated data quality control, pseudodata generation, and operational logging/coring guidance are other potential uses of data analytics and machine learning in the area of reservoir characterization (Brackenridge et al. 2022;Xu et al. 2019). ...

... It contributes significantly to understanding spatial concepts through the provision of a sense of presence in the learning sites (Fitzsimons and Farren, 2016;Zhao et al., 2022). Additionally, it can give the positive opportunities of geological understanding, interpretation, and application through the observation of virtual outcrops (Pugsley et al., 2021). ...

... In the UK SNS, the Laramide event is less evident than elsewhere in the Anglo-Polish Basin, but it is seen to coincide with the transition from chalk to mudstone deposition (Fig. 2). Finally, a period of tilt in the Neogene led to a progressive subcropping (and outcropping) of older sequences towards the west (Brackenridge et al. 2020). ...

The activity encompasses the Palu Koro, Walanae, Matano, Hamilton, and Sorong (south Sula-Sorong) faults, as well as subduction troughs represented by North Sulawesi, Sangihe, Tolo, and the Batui and Sula trusts. The Palu Koro fault, the Sulawesi trough, and the Sangihe trough are the predominant tectonic causes contributing to disaster development in the Sulawesi region [6], [7]. ...

... This cyclicity is considered to represent repeated sequences of grain size variation at various (orbital) scales. Many studies describe this contouritic seismic cyclicity (e.g., Llave et al., 2001Llave et al., , 2020Vandorpe et al., 2011;Liu et al., 2020), although most do not include a proper spectral analysis, instead inferring the presence of an orbital control by counting the number of visually distinct seismic units within a known time interval. A well-developed cyclostratigraphic pattern has been identified in the Gulf of Cadiz contourite depositional system with spectral analyses on normalized gamma ray logs time-series (Hernández-Molina et al., 2016), showing orbital cyclicity in the range of the Milanković temporal cycles (22 kyr, 23 kyr and 24.5 kyr precession, 44 kyr and 55 kyr obliquity and 85 kyr, 96 kyr, and 105 kyr shortterm eccentricity) and periods of 406 kyr and 420 kyr correlated with long-term eccentricity cycles. ...

... The circulation of water masses around Iberia leads to the development of bottom currents and rather unknown associated oceanographic processes, some of which impinge upon the seafloor with relatively high velocity and interact along the continental slope. The resulting contourite erosional and depositional features comprise extensive, complex and often poorly known CDSs in various geological settings, consituting valuable sedimentary records of margins evolution (see compilation from Hernandez-Molina et al., 2011;Llave et al., 2015aLlave et al., , 2015b. Therefore, the present work has three main objectives: (1) to combine previous work and new data on describing persistent or intermittent oceanographic processes associated with bottom currents circulation along the Iberia continental margins; (2) to evaluate their role in determining the shape, potential sedimentary products and evolution of the margins; and (3) to propose some future considerations contemplating the implications of these findings. ...
