Sundal, Anja; Nystuen, Johan Petter; Dypvik, Henning; Miri, Rohaldin; Aagaard, Per (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)In characterizing subsurface reservoirs for CO2 storage, the geological heterogeneity distribution is of importance with respect to the injectivity and migration paths. The object of this study is a saline aquifer of ...

Stange, Kurt Martin; Midtkandal, Ivar; Nystuen, Johan Petter; Murray, Andrew; Sohbati, Reza; Thomson, Warren; Spiegel, Cornelia; Kuss, Hans-Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Non-glaciated mountain headwater catchments feature high-resolution geomorphic archives, which provide important insight into erosive processes and sediment dynamics in mountain ranges. As such the Valle de la Fueva ...

Midtkandal, Ivar; Faleide, Thea Sveva; Faleide, Jan Inge; Planke, Sverre; Anell, Ingrid Margareta; Nystuen, Johan Petter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Two nested clinoform set types of different scales and steepness are mapped and analysed from high‐resolution seismic data. Restoration of post‐depositional faulting reveals a persistent pattern of small‐scale, high‐angle ...

Torgersen, Espen; Gabrielsen, Roy Helge; Ganerød, Morgan; van der Lelij, Roelant; Schönenberger, Jasmin; Nystuen, Johan Petter; Brask, Sofie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Brittle reactivation of plastic shear zones is frequently observed in geologically old terranes. To better understand such deformation zones, we have studied the >700 Ma long structural history of the Himdalen–Ørje Deformation ...

Mangerud, Jan; Birks, Hilary H; Halvorsen, Lene Synnøve; Hughes, Anna L.C.; Nashoug, Ole; Nystuen, Johan Petter; Paus, Aage; Sørensen, Rolf; Svendsen, John-Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We describe a sediment sequence comprising a thick till covered by thin beds of lacustrine sediments containing pollen and plant macrofossils derived from pioneer vegetation. Four consistent radiocarbon dates on terrestrial ...

Kumpulainen, R.A.; Hamilton, M.A.; Söderlund, U.; Nystuen, Johan Petter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Ottfjället Dyke Swarm (ODS) is a prominent component of the Ediacaran mafic magmatism associated with opening of the Iapetus ocean, and hosted in the Särv Nappe, Middle Allochthon of the Scandinavian Caledonides. A ...
