    • An experimental study of the effect of water and chlorine on plagioclase nucleation and growth in mafic magmas: application to mafic pegmatites 

      Heckmann, Paul; Iacono Marziano, Giada; Strmic Palinkas, Sabina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)
      In this study, the effects of H<sub>2</sub>O and Cl on the grain size and nucleation delay of plagioclase in basaltic magma were investigated using dynamic and equilibrium experiments at 1150 ◦C, 300 MPa, and oxygen fugacity between FMQ − 1.65 and FMQ + 0.05 (fayalite–magnetite–quartz). Each experiment consisted of five samples of basaltic composition (from the Hamn intrusion in Northern Norway) ...

    • Petrogenesis of zoned and unzoned mafic pegmatites: An insight from the Palaeoproterozoic mafic-ultramafic Hamn intrusion, Northern Norway 

      Heckmann, Paul; Strmic Palinkas, Sabina; Hansen, Harald; Iacono Marziano, Giada; Rajic, Kristijan; Forien, Melanie; Bergh, Steffen Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-03)
      Mafic pegmatites have been reported from various geological environments, including ophiolites, layered magmatic intrusions, and volcanic arcs, but their petrogenesis stayed poorly constrained. This study brings new mineralogical and geochemical data obtained from unzoned and zoned gabbroic pegmatites hosted by the 1.8 Ga mafic-ultramafic Hamn intrusion, Northern Norway, with an aim to improve our ...
