The Svalbard Composite Tectono-Stratigraphic Element is located on the north-western corner of the Barents Shelf and comprises a Carboniferous to Pleistocene sedimentary succession. Due to Cenozoic uplift the succession is subaerially exposed in the Svalbard archipelago. The oldest parts of the succession consist of Carboniferous to Permian mixed s...
Poster
Dahlin et al. (2020) shows the first digital outcrop model from the high Arctic Island of Bjørnøya. The model of the Landnørdingsvika cliff in SW Bjørnøya highlights a spectacularly exposed outcrop of the Mid-Late Carboniferous Landnørdingsvika and Kapp Kåre Formations. The succession shows the interplay between mid-late Carboniferous sea-level flu...
Conference Paper
An appraisal of ancient Earth’s climate dynamics is crucial for understanding the modern climate system and predicting how this might change in the future. Major climate-shift events in the Earth’s past demonstrate the scale, duration and response of the climate system to various global and local climate stressors. More than 650 million years of...

Svalbard is a Norwegian high Arctic archipelago, located halfway between the North Pole and mainland northern Norway at 74-81°N. Svalbard's geological record is exceptional, both in terms of outcrop quality and stratigraphic coverage within a relatively small area. The Devonian to Paleogene stratigraphic record is particularly well-exposed with onl...

Article
Fault‐controlled mixed siliciclastic‐carbonate‐evaporite depositional systems exhibit distinct sensitivity to tectonic and eustatic controls that are expressed in the sedimentary architecture. In the Upper Carboniferous Billefjorden Trough (Svalbard, Norway), up to 2000 m of a warm and arid climate syn‐rift basin fill comprises such depositional sy...

The renowned Festningen section in the outer part of Isfjorden, western Spitsbergen, offers a c. 7 km long nearly continuous stratigraphic section of Lower Carboniferous to Cenozoic strata. Tectonic deformation associated with the Paleogene West-Spitsbergen-Fold-and-Thrust belt tilted the strata to near-vertical, allowing easy access to the section...

Paleokarst breccias are a common feature of sedimentary rift basins. The Billefjorden Trough in the high Arctic archipelago of Svalbard is an example of such a rift. Here the Carboniferous stratigraphy exhibits intervals of paleokarst breccias formed by gypsum dissolution. In this study we integrate digital outcrop models (DOMs) with a 2D ground pe...
Article
The high Arctic is a remote place, where geoscientific research and teaching require expensive and logistically demanding expeditions to make use of the short field seasons. The absence of vegetation facilitates the use of modern photogrammetric techniques for the cost-effective generation of high-resolution digital outcrop models (DOMs). These geo...

The study describes the depositional development and sediment partitioning in a prograding paralic Triassic succession. The deposits are associated with the advance of large prism‐scale clinoforms across a shallower platform area. Approaching the platform, the limited accommodation and associated relative higher rates of deposition generated straig...

Cooling fracture orientations in diabase sills associated with the Cretaceous High Arctic Large Igneous Province and syn‐sedimentary Triassic faults help constrain a model for Svalbard's (NE Barents Shelf) Mesozoic stress field evolution. Fracture data from Edgeøya and adjacent islands in SE Svalbard, from S Spitsbergen, and from literature were us...

Full-text available
World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. They are interpreted to have interacted with north‐westerly progradation of a regional delta system. The syn‐kinematic successions...

The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, petroleum exploration already started onshore Svalbard in 1960 with three mapping groups from Caltex and exploration efforts by th...

Soil is one of the most important constituents of an ecosystem, playing a crucial role in many environmental reactions and processes. Despite the fact that many environmental studies were conducted in the vicinity of Longyearbyen, very little is known about the physical and chemical properties as well as mineralogy of soils occurring in this town....
Article
Analysis of the sedimentary architecture of the early Billefjorden Trough, an exceptionally well-exposed Carboniferous half-graben located in Svalbard, Arctic Norway, allows detailed reconstruction of fault development and basin geometry. Sedimentary facies distribution reveals facies variability in an early synrift fill, when an array of meso-scal...
Article
Full-text available
The Late Triassic outcrops on southern Edgeøya, East Svalbard, allow a multi‐scale study of syn‐sedimentary listric growth faults located in the pro‐delta region of a regional prograding system. At least three hierarchical orders of growth faults have been recognized, each showing different deformation mechanisms, styles and stratigraphic locations...
Article
Sedimentary basins containing igneous intrusions within sedimentary reservoir units represent an important risk in petroleum exploration. The Upper Triassic to Lower Jurassic sediments at Wilhelmøya (Svalbard) contains reservoir heterogeneity as a result of sill emplacement and represent a unique case study to better understand the effect of magmat...

The study combines facies analysis from sedimentary logs with large-scale pseudo 3D photogrammetric observations to provide a large-scale regional understanding of the Carnian depositional development of the area around SW Edgeøya, which was filled by strongly tidally influenced deltaic systems. The studied succession documents an early lowstand du...
Conference Paper
The Triassic outcrops on the island of Edgeøya document a complex depositional history reflecting infill by large-scale NW prograding shelf-prism scale deltaic systems which advanced across the Barents Shelf. This study combines facies analysis from sedimentary logs with large-scale pseudo 3D photogrammetric observations to provide a large-scale re...

The Upper Carboniferous Billefjorden Trough is an onshore analogue of the near contemporary rift basins development on the Barents Shelf. The basin fill of the Billefjorden Through shows an allover transgressive succession from fluvial red beds to mixed shallow marine carbonates, evaporites and sandstones. The evolution of the Billefjorden Trough...

An array of ten grabens/ half-grabens and their associated syn-tectonic 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 f...
Conference Paper
Studies of large-scale clinoform geometries in the Barents Sea and offshore New Zealand provide results on the shape, dimension and curvature of clinoforms and their along-strike changes. New inferences suggest that there may be links between clinoform shape parameters that offer the possibility to predict clinoform architecture, and to better unde...

Full-text available
The Late Triassic De Geerdalen Formation, exposed in Kvalpynten on Edgeøya (East Svalbard) comprises two parts: a faulted array of half-graben basins with a complex stratigraphic architecture related to syndepositional faulting, and an overlying, less disturbed, deltaic or estuarine succession. The seismic-scale (ca. 8 km x 500 m) cliff exposure al...

The late Carboniferous rifting phase affected most of the western Barents Shelf. The contemporary basin fills might contain potential petroleum systems. Onshore exposures of rift basin fill can be found in Svalbard, especially the Billefjorden Trough containing thick sabhka deposits interfingering with carbonate and siliciclastic layers. In this st...

Southwest Spitsbergen, Wedel Jarlsberg Land, consists of two Proterozoic terranes with differing structural and metamorphic histories. The northern terrane experienced two Early Palaeozoic deformation events both accompanied by greenschist-facies metamorphism of similar grade. The southern terrane records a Neoproterozoic pervasive amphibolite-faci...
