Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Braathen, Alvar; Ogata, Kei; Anell, Ingrid Margareta; Mulrooney, Mark Joseph; Zuchuat, Valentin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)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. ...

Zuchuat, Valentin; Midtkandal, Ivar; Poyatos-Moré, Miquel; Da Costa, Sigrid; Brooks, Hannah Louise; Halvorsen, Kristine; Cote, Nathan; Sundal, Anja; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Unconformities, by definition, correspond to erosional or nondepositional surfaces, which separate older strata below, from younger rocks above, encapsulating significant time gaps. However, recent studies have highlighted ...

Zuchuat, Valentin (Doctoral thesis / Doktoravhandling, 2019)This study presented in this doctoral thesis addresses the development of the Upper Jurassic Curtis Formation, outcropping in east-central Utah. The study suggests a separation of the Curtis Formation in three geological ...

Skurtveit, Elin; Sundal, Anja; Bjørnarå, Tore Ingvald; Soldal, Magnus; Sauvin, Guillaume; Zuchuat, Valentin; Midtkandal, Ivar; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Fracture stiffness and flow properties have been measured in the laboratory using naturally fractured fault rock samples from the Little Grand Wash fault, Utah, USA. We compare fracture closure and related flow change ...

Shehata, Amer A.; Kassem, Ahmed A.; Brooks, Hannah Louise; Zuchuat, Valentin; Radwan, Ahmed E. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mixed carbonate-siliciclastic systems are complex, and their development can sometimes be difficult to understand, given the various responses to each sub-environment to specific forcing, such as variation in sediment ...

Braathen, Alvar; petrie, elisabeth; Nystuen, Tonje; Sundal, Anja; Skurtveit, Elin; Zuchuat, Valentin; Gutierrez, Marte; Midtkandal, Ivar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Folds in porous sandstone in cases allow identification of progressive deformation in an evolving strain field. In the Navajo Sandstone of the km-scale Laramide-style monocline of the San Rafael Swell (Utah, USA), four ...

Zuchuat, Valentin; Sleveland, Arve; Pettigrew, Ross P.; Dodd, Thomas J.H.; Clarke, Stuart M.; Rabbel, Ole; Braathen, Alvar; Midtkandal, Ivar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Modern, tide‐dominated and tide‐influenced coastlines are characterized by a range of environments, including deltas, estuaries and lagoons. However, some tide‐dominated basins and related sedimentary units in the rock ...

Anell, Ingrid Margareta; Zuchuat, Valentin; Röhnert, A.D.; Smyrak-Sikora, Aleksandra; Buckley, Simon John; Lord, Gareth Steven; Maher, H.; Midtkandal, Ivar; Ogata, Kei; Olaussen, Snorre; Osmundsen, Per Terje; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)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 ...

Zuchuat, Valentin; Steel, Elisabeth; Mulligan, Ryan P.; Collins, Daniel S.; Green, J. A. Mattias (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Simulating hydrodynamic conditions in palaeo-ocean basins is needed to better understand the effects of tidal forcing on the sedimentary record. When combined with sedimentary analyses, hydrodynamic modelling can help ...
