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.

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.

Eos, Transactions American Geophysical Union, 1971 Work in rock magnetism during the last 4 years in the United States has been concentrated on several important intrinsic problems, the solutions of which are needed to answer some of the larger questions now being raised in paleomagnetism. The questions include whether it is feasible to measure variations in geomagnetic field intensity in rocks as old ...

Remagnetization of Marcellus Formation in the Plateau Province of the Appalachian Basin
Frontiers in Earth Science, 2019 An integrated paleomagnetic, magnetic fabric, and petrographic study of two cores (EC, oriented; DB, unoriented) in the Devonian Marcellus Formation from the Plateau Province (PA) indicates the presence of chemical remanent magnetizations (CRMs) and ...

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

Tracking Subsurface Active Weathering Processes in Serpentinite
Geophysical Research Letters, 2021 We conducted a novel study to capture the on‐going advancement of mineral weathering within a serpentinite formation by using an integrated approach of multi‐scale quantitative rock magnetic analyses and nano‐resolution geochemical imaging analyses.
