Rock magnetism linked to human brain magnetite [PDF]
, 1994 Magnetite has a long and distinguished career as one of the most important minerals in geophysics, as it is responsible for most of the remanent magnetization in marine sediments and the oceanic crust.

Variations in the Magnetic Properties of Meteoritic Cloudy Zone
Geochemistry, Geophysics, Geosystems, 2020 Iron and stony‐iron meteorites form the Widmanstätten pattern during slow cooling. This pattern is composed of several microstructures whose length‐scale, composition and magnetic properties are dependent upon cooling rate.

Investigating the utility of a high-temperature Thellier-style paleointensity experimental protocol
Earth, Planets and Space, 2021 High-quality data are vital to the research field of paleointensity, which has long suffered from poor-quality and/or sparse data. Previous paleointensity work has established that repeatedly heating specimens increases the opportunity for thermochemical

Paleomagnetism, rock magnetism and geochemical aspects of early Cretaceous basalts of the Paraná Magmatic Province, from Misiones, Argentina [PDF]
, 2006 The basalts of the Posadas Formation were extruded during the huge continental volcanism that affected the Parana Basin in the Lower Cretaceous. We have carried out a paleomagnetic and rock-magnetic study on samples collected along a basalt outcrop ...

Magnetic Vortex States in Small Octahedral Particles of Intermediate Titanomagnetite
Geochemistry, Geophysics, Geosystems, 2018 Fine particles of titanomagnetites (Fe3‐xTixO4, x > 0.5) in the pseudo‐single‐domain (PSD) size (0.5–20 μm) are important carriers of natural remanent magnetization in basalts.
