Deep-water sand transfer by hyperpycnal flows, the Eocene of Spitsbergen, Arctic Norway
Grundvåg, Sten-Andreas; Helland-Hansen, William; Johannessen, Erik P.; Eggenhuisen, Joris T.; Pohl, Florian; Spychala, Yvonne T. (Journal article; Peer reviewed, 2023)Flood-generated hyperpycnal flows are dense, sediment-laden, turbulent flows that can form long-lived, bottom-hugging turbidity currents, which undoubtedly transport large volumes of fine-grained sediments into the ocean. ... -
Fault-controlled fluid circulation and diagenesis along basin-bounding fault systems in rifts - Insights from the East Greenland rift system
Salomon, Eric; Rotevatn, Atle; Kristensen, Thomas Berg; Grundvåg, Sten-Andreas; Henstra, Gijs Allard; Meckler, Anna Nele; Albert, Richard; Gerdes, Axel (Journal article; Peer reviewed, 2020-11-05)In marine rift basins, deep-water clastics (>200 m) in the hanging wall of rift- or basin-bounding fault systems are commonly juxtaposed against crystalline “basement” rocks in the footwall. A distinct feature of such fault ... -
Field courses in sedimentology; how to improve students logging and sketching skills

Microstructure and fluid flow in the vicinity of basin bounding faults in rifts – The Dombjerg Fault, NE Greenland rift system
Salomon, Eric; Rotevatn, Atle; Kristensen, Thomas Berg; Grundvåg, Sten-Andreas; Henstra, Gijs Allard (Journal article; Peer reviewed, 2021)Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near ... -
Petroleum, coal and research drilling onshore Svalbard: a historical perspective
Senger, Kim; Brugmans, Peter; Grundvåg, Sten-Andreas; Jochmann, Malte Michel; Nøttvedt, Arvid; Olaussen, Snorre; Skotte, Asbjørn; Smyrak-Sikora, Aleksandra (Peer reviewed; Journal article, 2019)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, ... -
Sedimentology and palynology of the Lower Cretaceous succession of central Spitsbergen: integration of subsurface and outcrop data
Grundvåg, Sten-Andreas; Jelby, Mads Engholm; Śliwińska, Kasia Kamila; Nøhr-Hansen, Henrik; Aadland, Tore; Sandvik, Sara Elvelund; Tennvassås, Ingrid; Engen, Thea Marie; Olaussen, Snorre (Peer reviewed; Journal article, 2019-06-27)The Lower Cretaceous succession in Svalbard is commonly considered as an important analogue to age-equivalent strata on the Barents Shelf which are sporadically targeted by exploration wells. In this study, the stratigraphic ... -
Structural inheritance and rapid rift-length establishment in a multiphase rift: The East Greenland rift system and its Caledonian orogenic ancestry
Rotevatn, Atle; Kristensen, Thomas Berg; Ksienzyk, Anna Katharina; Wemmer, Klaus; Henstra, Gijs Allard; Midtkandal, Ivar; Grundvåg, Sten-Andreas; Andresen, Arild (Peer reviewed; Journal article, 2018-06)We investigate (i) margin‐scale structural inheritance in rifts and (ii) the time scales of rift propagation and rift length establishment, using the East Greenland rift system (EGR) as an example. To investigate the ... -
Structure and flow properties of syn-rift border faults: The interplaybetween fault damage and fault-related chemical alteration (Dombjerg Fault, Wollaston Forland, NE Greenland)
Kristensen, Thomas Berg; Rotevatn, Atle; Henstra, Gijs Allard; Peacock, David; Midtkandal, Ivar; Grundvåg, Sten-Andreas (Peer reviewed; Journal article, 2016-11)Structurally controlled, syn-rift, clastic depocentres are of economic interest as hydrocarbon reservoirs; understanding the structure of their bounding faults is of great relevance, e.g. in the assessment of fault-controlled ... -
The Svalbard Eocene-Oligocene (?) Central Basin succession: Sedimentation patterns and controls
Helland-Hansen, William; Grundvåg, Sten-Andreas (Journal article; Peer reviewed, 2021)A synthesis has been undertaken based on regionally compiled data from the post early Eocene foreland basin succession of Svalbard. The aim has been to generate an updated depositional model and link this to controlling ... -
Teaching with digital geology in the high Arctic: opportunities and challenges
Senger, Kim; Betlem, Peter; Grundvåg, Sten-Andreas; Horota, Rafael Kenji; Buckley, Simon John; Smyrak-Sikora, Aleksandra; Jochmann, Malte Michel; Birchall, Thomas; Janocha, Julian; Ogata, Kei; Kuckero, Lilith; Johannessen, Rakul Maria; Lecomte, Isabelle Christine; Cohen, Sarah M.; Olaussen, Snorre (Journal article; Peer reviewed, 2021)The Covid-19 pandemic occurred at a time of major revolution in the geosciences – the era of digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric ... -
Tracing Lower Cretaceous organic-rich units across the SW Barents Shelf
Hagset, Andreas Hallberg; Grundvåg, Sten-Andreas; Badics, Balazs; Davies, R; Rotevatn, Atle (Journal article; Peer reviewed, 2022)On the Barents Shelf, the northernmost and least explored hydrocarbon province of the Norwegian Continental Shelf, Upper Jurassic organic-rich shales have traditionally been given most attention as these represent the most ... -
Turbidites in the Eocene of Spitsbergen: can they tell us something about the Sørvestsnaget Basin?
Grundvåg, Sten-Andreas; Helland-Hansen, William; Safronova, Polina (Conference lecture, 2017)
