    Authigenic magnetite formation from goethite and hematite and chemical remanent magnetization acquisition 
    Till, Jessica L; Nowaczyk, N (Oxford University Press (OUP), 2018-03-08)
    The iron oxyhydroxide goethite is unstable at elevated temperatures and can transform to magnetite under reducing conditions. In this study, various heating experiments were conducted to simulate Fe-mineral transformations during pyrogenic or burial ...

    High‐Temperature Deformation Behavior of Synthetic Polycrystalline Magnetite 
    Till, Jessica L; Rybacki, E.; Morales, L.F.G.; Naumann, M. (American Geophysical Union (AGU), 2019-03)
    We performed a series of deformation experiments on synthetic magnetite aggregates to characterize the high‐temperature rheological behavior of this mineral under nominally dry and hydrous conditions. Grain growth laws for magnetite were additionally ...

    A luminescence-based chronology for the Harletz loess sequence, Bulgaria 
    Lomax, Johanna; Fuchs, Markus; Antoine, Pierre; Rousseau, Denis-Didier; Lagroix, France; Hatté, Christine; Taylor, Samuel N.; Till, Jessica L; Debret, Maxime; Moine, Olivier; Jordanova, Diana (Wiley, 2018-10-08)
    The Harletz loess‐palaeosol sequence is located in northwestern Bulgaria and represents an important link between well‐studied loess sequences in eastern Romania and further sites to the west of the Carpathians (e.g. Serbia and Hungary). The aim of ...

    Presumed magnetic biosignatures observed in magnetite derived from abiotic reductive alteration of nanogoethite 
    Till, Jessica L; Guyodo, Yohan; Lagroix, France; Morin, Guillaume; Menguy, Nicolas; Ona-Nguema, Georges (Elsevier BV, 2017-03)
    The oriented chains of nanoscale Fe-oxide particles produced by magnetotactic bacteria are a striking example of biomineralization. Several distinguishing features of magnetite particles that comprise bacterial magnetosomes have been proposed to ...
