Igneous sills are common components in rifted sedimentary basins globally. Much work has focused on intrusions emplaced at relatively shallow palaeodepths (0 – 1.5 km). However, owing to constraints of seismic reflection imaging and limited field exposures, deeper (>1.5 km) within not as well understood regard their emplacement mechanisms host-rock interactions. Results from a world-class, seismic-scale outcrop intruded Jurassic rocks East Greenland presented here. host have been studied...
Catchments provide water and sediment to downstream sedimentary systems, these form individual source-to-sink systems. Source-to-sink systems comprise adjacent linked segments, commonly hinterland catchments, alluvial- coastal plains, the continental shelf, slope submarine fan. The dimensions of catchment how it scales segments provides insight into tectonic controls that influence morphology sedimentation patterns in a basins evolution. In ancient successions, where routing system is buried...
Application of 3D seismic reflection data to igneous systems in sedimentary basins has led a revolution the understanding mafic sill complexes. However, there is considerable uncertainty on how geometries and architecture complexes within subsurface actually relates data. To provide constraints should be interpreted, we present synthetic seismograms generated from seismic-scale (22 × 0.25 km) outcrop East Greenland constrained by abundant field This study highlights overlying rocks adversely...
The high Arctic is a remote place, where geoscientific research and teaching require expensive logistically demanding expeditions to make use of the short field seasons. absence vegetation facilitates modern photogrammetric techniques for cost-effective generation high-resolution digital outcrop models (DOMs). These georeferenced can be used in pre-fieldwork activities help prepare traditional geological fieldwork, during fieldwork record observations, post-fieldwork conduct quantitative...
Present-day catchments adjacent to sedimentary basins may preserve geomorphic elements that have been active through long intervals of time. Relicts ancient in present-day landscapes be investigated using mass-balance models and can give important information about upland landscape evolution reservoir distribution basins. However, such methods are their infancy often difficult apply deep-time settings due later modification.
The Triassic-Jurassic transition marks an important change in the basin configuration of Greater Barents Sea. A contiguous with km-thick sedimentary successions changed into a partitioned uplift west and foreland basins east significant implication for infill history. Our study employs range different high-resolution datasets from distal part which unravels complex pattern differential erosion during this period. We record first time distinct angular unconformities between Upper Triassic...
Abstract The Greater Barents Sea Basin (GBSB) in Arctic Russia and Norway is an intracratonic basin that accommodated enormous amount of sediment during the Triassic. These deposits are up to 4.5 km thick over area 2,500,000 2 , consist marine mudstones mudstone‐rich fluvio‐deltaic topsets with sandstone‐dominated fluvial channels. well‐studied data‐rich, but regional correlation between different parts lacking. Provenance data from adjacent basins have been interpreted imply transport Ural...
Seismic modelling is necessary to understand elasticwave propagation in the subsurface. Modelling costeffective and insightful, as long adequate methods are used. An ideal seismic-modelling strategy generate complete synthetic seismograms for realistic earth models, then process them performed with real seismic data. These best obtained by full-wavefield (FW) approaches. FW therefore used extensive benchmarking studies, which may require joint effort of several institutions owing high...
Field education remains a cornerstone of geoscience training, yet logistical, environmental, and accessibility challenges necessitate innovative approaches to complement traditional field-based learning. This study investigates the potential digital field representations (DFRs), like photogrammetry dataset, drone-based imagery, geographic information systems, 3D globes, map layers, etc., as scalable accessible tools for in virtual reality applications. These DFRs allow students professionals...
Facies models for wave-dominated shorelines include an ‘offshore transition zone’ between shelfal mudstones and nearshore shoreface sandstones. Offshore transition-zone deposits are commonly tabular sandstone beds interbedded with continuous mudstone beds. However, observations from the Blackhawk Formation show that offshore zone locally consists of erosive-based ‘pinch-and-swell’ geometries containing steep-walled gutter casts, in areas larger than 6 × 2 km along strike dip. This increases...
Deposits of wave-dominated shorelines are typically considered to act as relatively simple hydrocarbon reservoirs and commonly modeled “tanks sand.” However, important heterogeneities that can barriers fluid flow occur at the parasequence, bedset, bed scales, especially in viscous oil or low-permeability fields. Heterogeneities parasequence bedset scales have been well studied, but discontinuous mudstone beds occurring within shoreface received little attention. The Book Cliffs Wasatch...

Abstract Tide‐dominated deltas have an inherently complex distribution of heterogeneities on several different scales and are less well‐understood than their wave‐dominated river‐dominated counterparts. Depositional models these environments based a small set ancient examples are, therefore, immature. The Early Jurassic Gule Horn Formation is particularly well‐exposed in extensive sea cliffs from which 32 km long, 250 m high virtual outcrop model has been acquired using helicopter‐mounted...
Abstract Models relating sediment supply to catchment properties are important in order use the geological record deduce landscape evolution and interplay between tectonics climate. Water discharge ( Q w ) is an factor widely used ‘ BQART ’ model, which relates load a set of measurable parameters. Although many factors this equation may be independently estimated with some degree certainty ancient systems, water certainly cannot. An analysis world database modern catchments 1255 entries...
Shear zones are common strain localization structures in the middle and lower crust play a major role during orogeny, transcurrent movements rifting alike. Our understanding of crustal deformation depends on our ability to recognize map shear subsurface, yet exact signatures seismic reflection data not well constrained. To advance understanding, we simulate how three outcrop examples (Holsnøy - Norway, Cap de Creus Spain, Borborema Brazil) would look different types using 2-D...
Abstract In recent years it has become clear that many shallow‐marine heterolithic and mudstone‐dominated successions are deposited as mud belts forming part of subaqueous deltas related to major fluvial sources either upstream or along shore. Here the Havert Formation is presented an ancient example this kind system. The in south‐western Barents Sea represents shelf margin clinoforms consisting predominantly deposits. Sediments were mainly derived from east (Ural Mountains), but a smaller...
Subsurface deposits in recently glaciated marine areas are highly heterogeneous, representing a range of glacial and postglacial environments processes including glacitectonism, overconsolidation, fluvial lacustrine deposition, transgression. These heterogeneities often linked to variations engineering properties, with important implications for the design installation offshore wind infrastructure. In this study we present an integrated geological characterization Sørlige Nordsjø II site,...
Rift-related magmatism resulting in widespread igneous intrusions has been documented various basins, including the Faroe Shetland Basin (UK), Voring and Møre basins (Norway), along NW Shelf of Australia. Seismic mapping, combined with fieldwork, resulted greater understanding subsurface intrusive plumbing systems but knowledge emplacement style mechanisms by which propagate is limited. The interpretation a 3D seismic dataset from Exmouth Sub-basin, Australia, identified numerous where close...

Abstract Clinoform surfaces are routinely used to mark transitions from shallow waters deep basins. This concept represents a valuable tool for screening potential reservoir intervals in frontier basins where limited data available. Variations the character of clinoform geometries and shoreline shelf‐edge trajectories indicators range different factors, such as palaeobathymetry, changes relative sea‐level sediment supply. Applications conceptual generalized models might, however, lead...
