    Quantified abundance of magnetofossils at the Paleocene–Eocene boundary from synchrotron-based transmission X-ray microscopy by Wang, Huapei, Wang, Jun, Chen-Wiegart, Yu-chen Karen, Kent, Dennis V.

    Published 2016
    “…Biogenic magnetite (Fe[subscript 3]O[subscript 4]) in the form of giant (micron-sized) spearhead-like and spindle-like magnetofossils, as well as nano-sized magnetotactic bacteria magnetosome chains, have been reported in clay-rich sediments in the New Jersey Atlantic Coastal Plain and were thought to account for the distinctive single-domain magnetic properties of these sediments. …”

    Dating North Pacific Abyssal Sediments by Geomagnetic Paleointensity: Implications of Magnetization Carriers, Plio-Pleistocene Climate Change, and Benthic Redox Conditions by Wanzhang Wang, Tilo von Dobeneck, Thomas Frederichs, Yang Zhang, Lester Lembke-Jene, Ralf Tiedemann, Michael Winklhofer, Dirk Nürnberg

    Published 2021-08-01
    “…Surprisingly, higher proportions of biogenic vs. detrital magnetite in the late Pliocene correlate with systematically lowered RPI values, which seems to be a consequence of magnetofossil oxidation rather than reductive depletion. …”

    Geomagnetic relative paleointensity and direction during the last 40,000 years obtained from a sediment core in the Nankai Trough by Ryoya Goto, Toshitsugu Yamazaki, Natsumi Okutsu, Juichiro Ashi

    Published 2024-01-01
    “…It was revealed that the magnetization of this core is carried largely by detrital magnetic minerals, although magnetofossils are also contained. Bulk magnetic properties show some temporal changes in magnetic concentration and grain size, but still homogeneous enough for reliable RPI estimations except for turbidites and volcanic ashes. …”
