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 ...

Magnetic properties of the Old Crow tephra: Identification of a complex iron titanium oxide mineralogy

, 2004
International audience[1] The mineralogy and grain-size distribution of the Fe-Ti oxide population of the Old Crow tephra bed, outcropping at the Halfway House loess deposit in central Alaska, are characterized through multiple low-and high-temperature ...

Symmetry and Nonstoichiometry as Possible Origin of Ferromagnetism in Nanoscale oxides [PDF]

, 2011
We show through density functional theory calculations that extended magnetic states can inherently occur in oxides as the size of the crystals is reduced down to the nanometer scale even when they do not explicitly include intrinsic defects.

Magnetic Properties of Ferritchromite and Cr‐Magnetite and Monitoring of Cr‐Spinels Alteration in Ultramafic and Mafic Rocks

Geochemistry, Geophysics, Geosystems, 2020
Spinel is a ubiquitous mineral in mafic/ultramafic rocks. Spinel cores chemistry is extensively used as a petrogenetic proxy while their alteration phases, ferritchromite, and Cr‐magnetite, are used as metamorphic grade indicators.

Micromagnetic Determination of the FORC Response of Paleomagnetically Significant Magnetite Assemblages

Geochemistry, Geophysics, Geosystems
Micromagnetic modeling allows the systematic study of the effects of particle size and shape on the first‐order reversal curve (FORC) magnetic hysteresis response for magnetite particles in the single‐domain (SD) and pseudo‐single domain (PSD) particle ...
