Compositional Features and Swelling Potential of Two Weak Rock Types Affecting Their Slake Durability
Selen, Lena; Panthi, Krishna Kanta; Mørk, Mai Britt Engeness; Sørensen, Bjørn Eske (Journal article, 2021)Weak and weathered rocks are well known for their sensitivity to changes in moisture content. Degrading behavior is common in weak rocks with moisture-sensitive mineral components and present numerous stability problems. ... -
Detrital zircons of the vast Triassic Snadd and De Geerdalen formations, Barents Shelf, reveal temporal changes in sediment source
Harstad, Trond Svånå; Slagstad, Trond; Kirkland, Christopher L.; Mørk, Mai Britt Engeness (Peer reviewed; Journal article, 2023)Studies of detrital-zircon age distributions from Triassic sedimentary rock successions on the Arctic Barents Shelf have resulted in different provenance interpretations. Here, we provide new U–Pb/Hf detrital-zircon data ... -
Fluid flow properties of the Wilhelmøya Subgroup, a potential unconventional CO2 storage unit in central Spitsbergen
Mulrooney, Mark Joseph; Larsen, Leif; Van Stappen, Jeroen; Rismyhr, Bjarte; Senger, Kim; Braathen, Alvar; Olaussen, Snorre; Mørk, Mai Britt Engeness; Ogata, Kei; Cnudde, Veerle (Journal article; Peer reviewed, 2018)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Geochemical, sedimentological, and petrographic study of Jurassic sediments and underlying weathered basement offshore Vesterålen.
Samuelsen, Lena Marie (Master thesis, 2022)En kjerne fra offshore Vesterålen i Nord-Norge har blitt logget og analysert ved bruk av ulike metoder. Kjernen består av sedimenter fra Måsnykan Formasjonen fra Jura over forvitret grunnfjell av gneis. Formålet med oppgaven ... -
The Hambergfjellet Formation on Bjørnøya – sedimentary response to early Permian tectonics on the Stappen High
Grundvåg, Sten-Andreas; Strand, Mathias; Paulsen, Christian Oen; Simonsen, Bjørn; Røstad, Jostein; Mørk, Atle; Mørk, Mai Britt Engeness (Peer reviewed; Journal article, 2023)On Bjørnøya, the exhumed crest of the Stappen High, the lower Permian (Cisuralian) Hambergfjellet Formation represents the only exposed part of the Bjarmeland Group carbonate platform, which occurs widely elsewhere in the ... -
The importance of trace element analyses in detrital Cr-spinel provenance studies: An example from the Upper Triassic of the Barents Shelf
Harstad, Trond Svånå; Mørk, Mai Britt Engeness; Slagstad, Trond (Peer reviewed; Journal article, 2021)Investigations of sandstone provenance often involve U–Pb dating and chemical/mineralogical investigations of detrital minerals that are stable in sediments. As most stable detrital minerals are from felsic–intermediate ... -
Innovative stabilization techniques for weak crushed rocks used in road unbound layers: A laboratory investigation
Barbieri, Diego Maria; Hoff, Inge; Mørk, Mai Britt Engeness (Journal article; Peer reviewed, 2019)The “Ferry-free coastal highway route E39” project includes building several long tunnels along the southwestern Norwegian coast. The tunnelling operations will generate a large quantity of blasted rocks; these could be ... -
Investigation on the Effect of Cyclic Moisture Change on Rock Swelling in Hydropower Water Tunnels
Selen, Lena; Panthi, Krishna Kanta; Vergara, Maximiliano R.; Mørk, Mai Britt Engeness (Peer reviewed; Journal article, 2021)This manuscript investigates the interaction between cyclic wetting and drying, material composition/structure and swelling potential of weathered rocks. Laboratory tests were performed at the Norwegian University of ... -
Organosilane and lignosulfonate as innovative stabilization techniques for crushed rocks used in road unbound layers
Barbieri, Diego Maria; Hoff, Inge; Mørk, Mai Britt Engeness (Peer reviewed; Journal article, 2020)The tunnelling operations connected to the construction of the new Norwegian E39 highway generate a considerable amount of blasted rocks. The local use of these rocks as construction materials in the unbound layers of the ... -
Sedimentology and petrography of the Svenskøya Formation on Hopen, Svalbard: an analogue to sandstone reservoirs in the Realgrunnen Subgroup
Lord, Gareth Steven; Mørk, Mai Britt Engeness; Mørk, Atle; Olaussen, Snorre (Journal article; Peer reviewed, 2019)On the island of Hopen, in the Svalbard Archipelago, the Svenskøya Formation is a succession 35 m in thickness, consisting primarily of sandstone beds and forming the youngest strata exposed on the island. We present a ...
