Deep-water sinuous channels: their development and architecture
(Doctoral thesis, 2011-12-02)The study combines an interpretation of 3D seismic and well-core dataset with laboratory experiments, process-based 3D numerical simulations and analysis of outcrop analogues to explore the varied architecture and formative ... -
Deformation bands in porous sandstones, their microstructure and petrophysical properties
(Doctoral thesis, 2008-02-27)Deformation bands are commonly thin tabular zones of crushed or reorganized grains that form in highly porous rocks and sediments. Unlike a fault, typically the slip is negligible in deformation bands. In this dissertation ... -
Deformation of sandstone reservoirs. Insight from experiments and field studies
(Doctoral thesis, 2014-09-18) -
Deglaciation of the Norwegian fjords
(Doctoral thesis, 2018-01-09)Melting glaciers and ice sheets are perhaps the most visible signs of a warming cli- mate. Glaciers are retreating on every continent, ice sheets are shedding icebergs into a warming ocean at an accelerating rate, and the ... -
Deltaic clinothems − Digital data capture, geometries, and reservoir implications
(Doctoral thesis, 2008-12-15)Subsurface reservoir models are typically limited by a lack of spatially accurate geometric data on bedform architecture and geometry, which are key controls on fluid flow. Outcrop analogues have long been utilized as a ... -
Development of extensional growth basins: A field based study, Svalbard, Norway
(Doctoral thesis, 2020-02-27)The growth style and evolution of syn-sedimentary faults influence the architecture of the basin and thus control both the geometries and distribution of sedimentary facies belts. The architecture of sedimentary basin fill ... -
Development of Gilbert-type deltas: sedimentological case studies from the Plio-Pleistocene of Corinth Rift, Greece
(Doctoral thesis, 2014-05-28)Gilbert-type deltas form where a river system debouches into a relatively deep marine or lacustrine basin, whereby the subaqueous delta slope is steep and fully dominated by sediment gravity-transport processes. These ... -
Dynamics of the Northeast Greenland Ice Stream: the role of geothermal heat and subglacial hydrology
(Doctoral thesis, 2019-11-15)Ice streams are rivers of fast flowing ice, crucial for the mass balance of ice sheets. The Greenland Ice Sheet shows a complex flow pattern, where a few major ice streams drain most of the ice sheet, contributing to sea ... -
Early post-deglaciation shorelines and sea-level changes along Hardangerfjorden and adjacent fjord areas, W. Norway
(Doctoral thesis, 2008-09-05) -
Earthquake Damage and Loss Assessment – Predicting the Unpredictable
(Doctoral thesis, 2013-05-10) -
Ecology and genomic diversity of iron-oxidizing bacteria at Arctic deep-sea hydrothermal vents: Lessons from genome-resolved metagenomics and microscopy
(Doctoral thesis, 2024-05-08)Jernoksiderende bakterier er globalt utbredt og har betydelig innvirkning på syklusen av jern i miljøet. Imidlertid har få slike bakterier blitt dyrket i laboratoriet og det finnes lite kunnskap om hvordan ulike miljøforhold ... -
Effects of magmatic intrusions on temperature history and diagenesis in sedimentary basins – and the impact on petroleum systems
(Doctoral thesis, 2020-04-23)For many volcanic basins, the thermal effect of igneous intrusions is decisive for their petroleum potential because such thermal impact may lead to maturation of organic material in areas that otherwise would remain ... -
Exhumation of the Caledonian Orogenic Infrastructure in West Norway : Concepts – Structures – Ages – Reactivation
(Doctoral thesis, 2020-05-19)Domes of high-grade metamorphic rocks are found in recent and ancient orogens alike. They commonly expose parts of the deep interior of mountain belts, the so-called orogenic infrastructure. This thesis explores the ... -
Experimental investigations of Magnetization processes in Chinese loess
(Doctoral thesis, 2011-11-25) -
Facies composition and scaling of extensional faults in sedimentary rocks and its applications to modelling of fault zones
(Doctoral thesis, 2010-01-08) -
From mountains to basins: geochronological case studies from southwestern Norway, Western Australia and East Antarctica
(Doctoral thesis, 2012-03-02) -
Generation of intermediate-depth earthquakes and the fate of subduction fluids : Insights from mantle wedge seismicity and case studies in the Western Hellenic subduction zone
(Doctoral thesis, 2019-06-07)The occurrence of intermediate depth earthquakes at 50-300 km depth in subduction zones is puzzling, because high temperatures and pressures at these depths do not allow standard brittle failure. Instead, two main candidate ... -
Geologic controls on fluid flow and seismic imaging of faults in carbonate rocks : Insights from quantitative outcrop analysis and reflection seismic modeling
(Doctoral thesis, 2023-06-16)Utforsking av undergrunnen har historisk sett hovudsakleg vore drive av økonomiske insentiv gjennom leiting etter hydrokarbon og andre geologiske ressursar. I nyare tid, derimot, har geologiens rolle i det grøne skiftet ...
