U-Pb zircon provenance of metamorphosed clastic sediments in the Brusque Metamorphic Complex, Dom Feliciano Belt, southeastern Brazil
(Master thesis; Mastergradsoppgave, 2018-05-15)The Brusque Metamorphic Complex is situated in the northern part of the Dom Feliciano Belt in the state of Santa Catarina, southeastern Brazil. The complex is composed of Neoproterozoic sequences of volcanic and sedimentary rocks, which were folded and metamorphosed at greenschist to low-amphibolite facies conditions. U-Pb dating of detrital zircon grains in five samples of clastic metasedimentary ... -
Undersøkelse av ustabilt fjellparti ved Adjet, Storfjord, Troms. Betydningen av ulike kategorier av glideplan i berggrunnen og mekanismer for utglidning
(Master thesis; Mastergradsoppgave, 2015-05-15)Strukturelle element i berggrunnen kan ha stor betydning for utvikling av ustabile fjellparti og fjellskred. I dette studiet vil det fokuseres på hvilken rolle strukturelle element i berggrunnen har hatt å si for skredhendelsene og deformasjonen i området og hvordan disse har preget det geologiske bildet. Det ustabile fjellpartiet er lokalisert på fjellet Adjet ved tettstedet Skibotn i Storfjord ... -
The upper Paleozoic regional development of the Ottar basin from seismic 2D interpretation
(Master thesis; Mastergradsoppgave, 2018-05-15)The Ottar basin is not yet formally defined, but is a known structural element situated under the Bjarmeland Platform in the southwestern Barents Sea, buried beneath thick, flay-lying Mesozoic strata. This thesis focuses on delineating the informal upper Paleozoic Ottar basin. The delineation presented, is based on lateral/vertical variations in lithology and the surrounding tectonic setting of the ... -
Upper Triassic to lower Cretaceous tectonostratigraphic development of the Barents Sea South East
(Master thesis; Mastergradsoppgave, 2020-05-27)The aim of this study is to investigate the tectonic- and evolutionary differences between major structural elements of the Barents Sea South East (BSSE) during the uppermost Triassic to lower Cretaceous. The study area comprises the following structural elements: the Bjarmeland- and Finnmark platforms, the Nordkapp- and Tiddlybanken basins, the Signalhorn-, Haapet- and Veslekari domes and the ... -
Use of 2D-seismic data and available wells to investigate the source potential of the Palaeozoic interval in the Loppa High area, SW Barents Sea
(Master thesis; Mastergradsoppgave, 2018-05-15)While most established plays in the Barents Sea have occurred in the Mesozoic, the Alta and Gohta discoveries prove a new carbonate play concept, with a source rock that does not stem from the Jurassic. Based on depositional environment and TOC values from the Palaeozoic interval a source rock with Top Ørn as its bottom and Top Røye as its top was interpreted. Basin modelling carried out on this ... -
The Use of Foraminiferal Geochemistry to Investigate Methane Seepage at the Svyatogor Ridge, Arctic Ocean
(Master thesis; Mastergradsoppgave, 2022-05-12)Methane is a greenhouse gas contributing to contemporaneous global warming, and seepage is one of the ways through which it migrates from the deep sedimentary basins, all the way up to the hydro- and atmosphere. The study of methane seepage is still young as scientists are yet to discover most seep sites as well as seep associated biological species. A record of past methane seepage can be derived ... -
Veikimorener i Norrbotten, Nord-Sverige – dødislandskap og morenebelter fra siste istid. Geomorfologisk tilnærming og GPR-profilanalyse av veikimorener innen den nordligste buen av veikimorenebeltet – Lainiobuen
(Master thesis; Mastergradsoppgave, 2020-12-30)Skandinavias glasiasjonshistorie er enda ikke kontinuerlig sammensatt for weichselistiden. I forhold til det fennoskandiske isskjoldet har nye studier avdekket alternative geokronologiske tolkninger for tidlig og midt weichsel i Nord-Sverige. Veikimorenelandskapet ble dannet over en stadial-interstadial syklus korrelert til tidlig weichsel av Lagerbäck (1988). Dette motstrides av moderne vitenskapelige ... -
Volume measurements and change of Longyearbreen and Tellbreen, Svalbard
(Master thesis; Mastergradsoppgave, 2017-08-12)Climate change is a comprehensive field of research. The cryosphere is only a small portion of the entire spectrum but is still a very important constituent to try and understand. Thermal expansion of the oceans is the second largest cause for sea level rise around the world after the global melting of glaciers and ice sheets combined. Even the smallest valley glaciers, with small individual volumes, ...
