(Master thesis / Masteroppgave, 2015)The main objective of this study is to attempt to correlate twelve (12) core and (1) one outcrop source rock samples, recovered from the Hammerfest Basin, the Nyslepp/Måsøy Fault Complex, the Finnmark Platform, the Nordkapp ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The Freetown Layered Complex (FLC) is a massive mafic layered intrusion cropping out along the coast of Sierra Leone. The present combined geochemical and geochronological (40Ar/39Ar on plagioclase: 201·7 ± 0·7 and 202·3 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Spanish Central System (SCS) contains several suites of Palaeozoic mafic igneous intrusions with contrasting geochemical affinity: Ordovician tholeiitic metabasites, Variscan calc-alkaline gabbros (Gb1) and microdiorites ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The spectacular Lusi mud-eruption started in northeast Java the 29th of May 2006. Despite extensive research, the origin of the erupted water remains elusive and poorly constrained. Here we present a comprehensive study ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract A vast portion of the plumbing system of the Siberian Traps Large Igneous Province (STLIP) is emplaced in the Tunguska Basin, where borehole data reveal ubiquitous and abundant sills with great lateral extension. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The Peräpohja belt comprises a greenschist to amphibolite facies; multiply-folded supracrustal sequence of quartzites; mafic volcanics; carbonate rocks; black shales; mica schists and greywackes deposited from ca. 2.44 Ga ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Multi-decadal mass loss estimates are available for few glaciers of Central Asia. On Abramov Glacier (Pamir-Alay, Kyrgyzstan), comprehensive long-term glaciological measurements have been carried out from 1968 to ...

(Master thesis / Masteroppgave, 2007)Glaciers and ice masses are very important components of the earth system both in terms of global water storage and as climate indicators. The amount of water tied up in glaciers and ice caps is equivalent to about 69 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Today's geodynamic models can, often do and sometimes have to become very complex. Their underlying, increasingly elaborate numerical codes produce a growing amount of raw data. Post-processing such data is therefore ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)We present geodynamic models featuring mantle plumes that are almost exclusively created at the margins of large thermo‐chemical piles in the lowermost mantle. The models are based on subduction locations and fluxes inferred ...
-
(Doctoral thesis / Doktoravhandling, 2016)In plate tectonics scientists study the present and past motions of the lithospheric plates over the Earth’s surface. The reconstruction of the location and orientation of the continents and oceans in deep time is referred ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We present the first thermal model for the lithosphere in Turkey, which shows a highly heterogeneous pattern associated with mosaics of the Tethyan and modern subduction systems. We calculate a regionally average crustal ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Geological modeling currently uses various computer-based applications. Data harmonization at the semantic level using ontologies is essential to make these applications interoperable. Since geo-modeling is part of several ...
-
(Research report / Forskningsrapport, 2023)This report compiles previously unpublished analytical data from two cores and an outcrop section of the sedimentary rocks of Middle-Upper Devonian age bundled in the Horn River Group in central Mackenzie Valley between ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In the oil and gas industry, during exploration prospect assessment, explorationists rely on ad hoc manual work practices and tools for developing and communicating multiple hypothetical geological scenarios of the prospect. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The vein-type Chomalu polymetallic epithermal deposit, located in the Tarom-Hashtjin Metallogenic Province (THMP), western Alborz, formed in two separate mineralized zones controlled by fault zones within andesite and ...
