    Rapid regional perturbations to the recent global geomagnetic decay revealed by a new Hawaiian record

    The dominant dipolar component of the Earth’s magnetic field has been steadily weakening for at least the last 170 years. Prior to these direct measurements, archaeomagnetic records show short periods of signi...

    Remagnetization mechanism of Lower Cretaceous rocks from the Organyà Basin (Pyrenees, Spain)

    Widespread Cretaceous remagnetization is documented in several Mesozoic basins in North Central Spain. Organyà Basin (South Central Pyrenean foreland) is atypical in the sense that the lower part of the rock s...

    Magnetic Anisotropy as an Aid to Identifying CRM and DRM in Red Sedimentary Rocks

    To further evaluate the potential of magnetic anisotropy techniques for determining the origin of the natural remanent magnetization (NRM) in sedimentary rocks, several new remanence anisotropy measurement tec...

    Changes in Magnetic Parameters After Sequential Iron Phase Extraction of Eastern Mediterranean Sapropel S1 Sediments

    Iron is distributed over different minerals (i.e. silicates, pyrite, detrital oxides) that are present in a sediment sequence that formed under anoxic conditions. After post-depositional re-oxidation of the se...

    Paleomagnetism and Cyclostratigraphy of the Middle Ordovician Krivolutsky Suite, Krivaya Luka Section, Southern Siberian Platform: Record of Non-Synchronous NRM-Components or a Non-Axial Geomagnetic Field?

    The Middle Ordovician Volginsky and Kirensky fossil zones were sampled in the Krivaya Luka section (Krivolutsky suite) that outcrops along the Lena river in Siberia. The Volginsky and Kirensky zones are coeval...

    Mössbauer, X-ray fluorescence and paleomagnetic studies of deep-sea sediments from the Peru Basin: two million years of sedimentation history

    Sediment cores with different sub-bottom depths (I: 45 cm and II: 700 cm) from the Peru Basin have been investigated. From the depth profile of the relative amount of Fe(II) a redox zone is obtained which corr...

    Magnetic Properties of Low-Ca Fly Ash: A Rapid Tool for Fe-Assessment and a Survey for Potentially Hazardous Elements

    Between 20 and 50 per cent of the total iron in low-Ca fly ashes resides in low-substitution magnetite spinel with Curie temperatures in between 565 and 590°C. A TEM study reveals that the spinel consists of a...
