Subsequent to a widespread hiatus at the top of the Permian on western Svalbard, the Triassic Vardebukta, Tvillingodden and Bravaisberget formations were deposited. In this thesis, the sedimentology, geochemistry and diagenesis are investigated to determine the depositional environment and basinal setting of the Triassic deposits. In the investigated profile on Mariaholmen, only the upper part ...

Steindalen er lokalisert sør på Lyngenhalvøya, i Troms fylke. Steindalsbreen er en av de lettest tilgjengelige breer i området. Dette gjør breen til et yndet turmål, men det gjør det også lettere å studere en bre på nært hold. Undersøkelse av Steindalsbreen har foregått ved hjelp av feltturer til området, ved å studere foto og flybilder over området og ved å sammenstille data samlet over mange år, ...

On Uløya, an island located east of the Lyngen peninsula in northern Troms, Norway, four Caledonian nappes are exposed. These are from bottom to top: part of the Kalak Nappe Complex (KNC), the Vaddas, the Kåfjord and the Nordmannvik nappe. In the present study the geology of these nappes is described, macroscopic and microscopic deformation structures are analyzed, and phase equilibrium modeling is ...

2D seismic data have been analysed to study the Cenozoic pre-glacial sedimentary environment on the southwest Barents Sea margin and the Lofoten Basin. Based on a seismic stratigraphic analysis and correlation to previous work in the area, the pre-glacial seismic unit G0 has been subdivided into four. The four units have been described and discussed with regards to the geometry and internal seismic ...

Large slowly creeping rock slope deformations, with an annual displacement in the range of millimeters to centimeters, have been prone to rapid catastrophic failures in the past. This master thesis focuses on the unstable rock slope of Dusnjárga in Northern Norway. A sudden rapid failure of Dusnjárga would pose a threat to the local society in Lille Altafjord and Burfjord, due to potential secondary ...

This thesis presents the results of august Sea Surface Temperature reconstructions from marine diatom assemblages in samples from core Ga3-2 retrieved from Narsaq Sound, inside the Ikersuad fjord, South Greenland. The diatom samples provide a high-resolution (~30-year) reconstruction dating between 890 and 1660 CE (common era). The results show variable conditions with warm periods between 960 and ...

The sediment core HH15-1255PC has been analyzed to reconstruct the climate in the Fram Strait during the last 45,000 years. The coring site is located west of Svalbard on the Vestnesa Ridge, a contourite drift with a high-resolution sedimentary record (Plaza-Faverola et al., 2015). This ridge also includes a pockmark field formed by methane seepage (Vogt et al., 1994). The core HH15-1255PC is a ...

This thesis combines a geological model with a mathematical model to describe the vertical propagation of a gas plume through layers with different physical properties. The geological model is based on geophysical data from the Sørvestsnaget Basin and the mathematical model is derived based on the classical Buckley-Leverett theory for two-phase flow. The model estimates the velocity of a vertical ...

Winter tourism in Tromsø has increased significantly over the last years, consequently also the skiing tourism. It is advertised that Tromsø has a mild coastal climate compared to other destinations at similar latitudes. Existing snow climate classes separate covers into a maritime, continental and a transitional class where persistent weak layers are rare in the maritime class. Rain and average air ...

The Dom Feliciano Belt in Uruguay represents a counterpart of the Gariep Belt in Namibia and these two belts are presently considered as relics of one orogen split by the Atlantic Ocean. In this study, two presumed flysch samples from the Marmora Terrane of the Gariep Belt in Namibia, and five samples from potential source areas in the Nico Perez Terrane of the Dom Feliciano Belt in Uruguay have ...
