  • A new age model for the Ordovician (Sandbian) K-bentonites in Oslo, Norway 
    Ballo, Eirik Magnus Gottschalk; Augland, Lars Eivind; Hammer, Øyvind; Svensen, Henrik (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    During the Late Ordovician, large explosive volcanic eruptions deposited worldwide K-bentonites, including the Millbrig and Deicke K-bentonites in North America and the Kinnekulle K-bentonite in Scandinavia. We have studied ...
  • A new high-resolution stratigraphic and palaeoenvironmental record spanning the End-Permian Mass Extinction and its aftermath in central Spitsbergen, Svalbard 
    Zuchuat, Valentin; Sleveland, Arve; Twitchett, Richard; Svensen, Henrik; Turner, Holly E; Augland, Lars Eivind; Jones, Morgan Thomas; Hammer, Øyvind; Hauksson, Bjarki; Haflidason, Haflidi; Midtkandal, Ivar; Planke, Sverre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Research on the Permian-Triassic boundary (PTB) along the northern margins of Pangaea (exposed today in the Arctic region) has been heavily reliant on field observations, where data resolution was consequently determined ...
  • Sylfjellet: a new outcrop of the Paleogene Van Mijenfjorden Group in Svalbard 
    Jochmann, Malte Michel; Augland, Lars Eivind; Lenz, Olaf; Bieg, Gerd; Haugen, Turid; Grundvåg, Sten-Andreas; Jelby, Mads E.; Midtkandal, Ivar; Dolezych, Martina; Hjálmarsdóttir, Hanna Rósa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    A hitherto unrecognized Paleogene outcrop has been discovered at Sylfjellet, a mountain located at the northern side of Isfjorden, Svalbard. The strata, which cover an area of 0.8 km2, have until now been assigned to the ...
  • Titanite links rare-element (meta-)pegmatite mineralization to Caledonian metamorphism 
    Zhou, Haoyang; Müller, Axel; Augland, Lars Eivind; Kristoffersen, Magnus; Erambert, Muriel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The metamorphic reworking of mineralized pegmatites during orogenesis remains unclear, making the genesis and the tectonomagmatic significance of pegmatite mineralization obscure. This study demonstrates the multiple ...
  • Two-stage regional rare-element pegmatite formation at Tysfjord, Norway: implications for the timing of late Svecofennian and late Caledonian high-temperature events 
    Müller, Axel; Romer, Rolf L.; Augland, Lars Eivind; Zhou, Haoyang; Rosing-Schow, Nanna; Spratt, John; Husdal, Tomas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract Pegmatite fields within granite plutons are commonly considered to have formed from residual melts of their host. This is not always true as demonstrated by the Tysfjord granite gneiss and its two groups of ...
