Anatomy of a deep crustal volcanic conduit system; The Reinfjord Ultramafic Complex, Seiland Igneous Province, Northern Norway
Grant, Thomas; B. Larsen, Rune; Anker-Rasch, Lars; Grannes, Kim Rune Bragstad; Iljina, Markku; McEnroe, Suzanne; Nikolaisen, Even; Schanche, Mona; Øen, Endre (Peer reviewed; Journal article, 2016)The Reinfjord Ultramafic Complex, Seiland Igneous Province represents a lower crustal magma chamber (25–30 km depth) that likely records a deep conduit system for mantle derived melts ascending through the continental ... -
Hysteresis of Natural Magnetite Ensembles: Micromagnetics of Silicate‐Hosted Magnetite Inclusions Based on Focused‐Ion‐Beam Nanotomography
Nikolaisen, Even; Harrison, Richard; Fabian, Karl; McEnroe, Suzanne (Peer reviewed; Journal article, 2020)Three‐dimensional geometries of silicate‐hosted magnetic inclusions from the Harcus intrusion, South Australia have been determined using focused‐ion‐beam nanotomography (FIB‐nt). By developing an effective workflow, the ... -
