Microstructural analysis of coal-bearing deformation bands at Wangaloa, New Zealand
(Master thesis, 2021-11-22)Deformation bands are defined as tabular, millimeter to centimeter wide zones of localized strain that commonly form in porous granular rock. Deformation bands have been studied in great detail over the last four decades ... -
Microstructure and fluid flow in the vicinity of basin bounding faults in rifts – The Dombjerg Fault, NE Greenland rift system
(Journal article; Peer reviewed, 2021)Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near ... -
Mid-Pliocene Atlantic Meridional Overturning Circulation simulated in PlioMIP2
(Journal article; Peer reviewed, 2021)In the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2), coupled climate models have been used to simulate an interglacial climate during the mid-Piacenzian warm period (mPWP; 3.264 to 3.025 Ma). Here, we compare ... -
Mid-Pliocene West African Monsoon rainfall as simulated in the PlioMIP2 ensemble
(Journal article; Peer reviewed, 2021)The mid-Pliocene warm period (mPWP; ∼3.2 million years ago) is seen as the most recent time period characterized by a warm climate state, with similar to modern geography and ∼400 ppmv atmospheric CO2 concentration, and ... -
Middle to Late Triassic (Ladinian to Carnian) palynology of shallow stratigraphic cores 7831/2-U-2 and 7831/2-U-1, offshore Kong Karls Land, Norwegian Arctic
(Master thesis, 2015-11-20)During the Triassic, the Barents Shelf was situated on the northwestern corner of the Pangaea supercontinent as a large epicontinental seaway. Into early Late Triassic (Carnian), a major delta, prograding from the southeast ... -
Middle to Late Triassic (late Ladinian - late Carnian) palynology of the shallow stratigraphic core 7534/4-U-1, Sentralbanken High, Northern Barents Sea
(Master thesis, 2015-09-11)In the Triassic period, a large seaway developed on the northern coast of Pangea, in the area which is the present-day Barents Sea. Deposition of sediment sourced from the Uralian Mountains in-filled this sea during the ... -
Miljøkonsekvenser av tidligere gruvedrift på Litlabø, Stord
(Master thesis, 2023-06-01)Gruvedrift medfører miljøutfordringer, der håndteringen av sulfidholdige overskuddsmasser er spesielt utfordrende siden oksidering og forvitring av disse massene ofte medfører sur avrenning og utlekking av miljøskadelige ... -
Mineraldannende prosesser, biosignaturer og finkornede sedimenter i karstgrotter ved Reingardslivatnet, Mo i Rana
(Master thesis, 2018-09-11)Reingardslisystemet er et grottesystem utviklet i en marmorsone som strekker seg 2,5 km i øst-vestlig retning i Reingardslia (Mo i Rana). Systemet regnes i dag som et av de lengste grottesystemene i Norge med en total ... -
Mineralogical controls on the weathering characteristics of arid continental deposits of the Colorado Plateau
(Master thesis, 2015-06-01)The Permian to Jurassic stratigraphy of the Colorado Plateau includes a number of units that were deposited under arid depositional conditions. These units each show distinctive weathering characteristics which cannot ... -
Mineralogical distribution and genetic aspects of cobalt at the active Fåvne and Loki’s Castle seafloor massive sulfide deposits, Arctic Mid-Ocean Ridges
(Journal article; Peer reviewed, 2023)The demand for responsibly sourced cobalt has increased dramatically as a result of the global transition to ‘fossil-free’ electromobility. However, the distribution, mineralogical expressions and mechanisms of concentration ... -
Minibasin depocentre migration during diachronous salt welding, offshore Angola
(Peer reviewed; Journal article, 2019)Salt tectonics is an important part of the geological evolution of many continental margins, yet the four‐dimensional evolution of the minibasins, the fundamental building block of these and many other salt basins, remains ... -
Minimum 1D velocity model and local magnitude scale for Myanmar
(Journal article; Peer reviewed, 2019)Earthquake monitoring in Myanmar has improved in recent years because of an increased number of seismic stations. This provides a good quality dataset to derive a minimum 1D velocity model and local magnitude (ML) scale ... -
Miocen utvikling av Vøringbassenget, basert på 2D multikanals seismikk
(Master thesis, 2010)2D multikanals seismikk, i kombinasjon med brønndata, er i denne studien benyttet for å studere de kenozoiske sedimentene i Vøringbassenget. I tillegg til den seismiske studien er fire brønner knyttet sammen med det seismiske ... -
