  Resolution and illumination issues in seismic data curtails identification of fault geometries and fault-initiated rock damage when mapping subsurface faults. Seismic modelling can be utilized to bridge the gap in identifying what can be imaged with certainty in seismic data, with respect to the original geology, especially when also comparing to outcrop data. In this study, we explore how seismic modelling can distinguish between real structures versus seismic artefacts. 2(3)D Point-Spread-Function based convolution modelling is used in a sensitivity study. One input is detailed fault interpretations of high-resolution P-Cable data and comparable conventional 3D seismic data from the Hoop area in the Barents Sea. Another dataset comes from detailed fault geometries observed in outcrops, which were used to build geological models as input to the seismic modelling. In addition to the host-rock lithofacies, parameters of importance for the geological model building include overall fault geometry and the distribution of architectural elements (fault facies) within the fault zone. By varying fault input, lithofacies, a wide range of frequencies, and illumination, we analyse a variety of synthetic seismic images. Finally we compare our modelled outcomes with seismic data from the Hoop area. The scope of the workflow is to increase confidence in seismic interpretations and to identify limitations in the analysis of steep, normal faults in seismic data.

  Large-scale cliff sections on Edgeøya, an island in the eastern part of the Svalbard Archipelago, comprise mostly Triassic sedimentary successions, and are onshore outcrops of formations found on the offshore Barents Shelf. These outcrops are of high interest for studying the subsurface geology found offshore on the Barents Shelf, using seismic-scale features such as small-scale growth faults, paralic deposits and low-angle clinoforms (Anell et al., 2016). At Kvalpynten, an outcrop at the southern end of Edgeøya, these features can be observed, providing the opportunity to compare offshore seismic data with the outcrop expression using seismic modelling. Synthetic seismic modelling provides a means of aiding interpretation of seismic data by quantitatively and qualitatively assessing resolution, scale and level of detail of modelled onshore structures (Lecomte et al., 2015). This can give valuable insights into potential resolution and survey parameter issues, as well as limitations with seismic data. Developments in digital outcrop modelling techniques, such as lidar and photogrammetry, now allow the accurate and high-resolution capture of large and inaccessible outcrop sections, at scales comparable with seismic vertical resolution. This opens up new possibilities for generating georeferenced input to synthetic seismic modelling, which allows generation of highly visual end products for educational purposes. This contribution presents a virtual field trip to the Triassic outcrops at Kvalpynten. The dataset is based on virtual outcrop models collected using boat-based photogrammetry, covering over 10km of continuous cliff sections. The 3D outcrop model is combined with geological interpretations, logs, field photos and information panels, as well as regional elevation data to set the context of the trip. In addition, synthetic seismic data are fused with the virtual outcrop models to highlight the scale of the exposures compared to offshore seismic data. The combined dataset is explored in LIME, a high performance viewer designed for displaying disparate geospatial and field datasets (http://virtualoutcrop.com/lime).

Vis sammendrag

  An array of ten grabens/ half-grabens and their associated syntectonic basin fill (averaging approx. 700 m across) are exposed along a 9 km cliff section at Kvalpynten, Edgeøya, offering a unique opportunity to study the silisiclastic architecture of listric graben basin fill. The exposures at Kvalpynten provide a unique opportunity to correlate fault-controlled sedimentary architecture on the scale of meters to hundreds of meters with detailed facies relationships, and thus fault-induced differential accommodation with the depositional environments that filled it. The basins developed in the Late Triassic, during the deposition of the Early Carnian to Early Norian deltaic successions of Tchermakfjellet and De Geerdalen formations which is approximately the onshore equivalent to the offshore Snadd Formation. The lowermost part of the ca 400 m high Kvalpynten cliff section reveals a number of NW–SE striking growth faults with 50–100 m offset, which bound basins filled with shale and sandstone wedges. Up section, the growth faults tip out, and are buried by undeformed deltaic deposits. Integrated field studies including sedimentology and structural geology combined with surfaces mapping on a photogrammetric virtual outcrop model allowed incremental reconstruction of the grabens/ half-grabens evolution. Four transgressive surfaces were identified and mapped, allowing correlation of the sandstone packages between each basin. The sequence of faulting has been defined with respect to the mapped flooding surfaces. Faulting clearly occurred in several phases as evident by the syn-kinematic fault’s control on sediments of different ages, and from the occurrence of later forming faults rotating earlier formed fault blocks. In general, early faults defined a relatively symmetrical basin configuration whereas later phases of movement were localized mainly along south-dipping faults. This gave rise to a change to more asymmetric basins and to the formation of asymmetric, composite sedimentary bodies with stacked shoreface and offshore transition deposits. Locally, fault crests were eroded. Our sedimentological observations suggest that tidal processes were dominant during sandstone deposition within the grabens/half-grabens, expressed by the widespread occurrence of tidal bar and tidal flat deposits.
