Magnetic fabric analysis of deformed rocks in the Riiser-Larsen Main Shear Zone, East Antarctica [PDF]

, 2005
Anisotropy of magnetic susceptibility (AMS) in deformed rocks in the Riiser-Larsen Main Shear Zone (RLMSZ) was analyzed in order to demonstrate the changes in rock magnetic properties due to deformation.

A case study of the internal structures of gossans and weathering processes in the Iberian Pyrite Belt using magnetic fabrics and paleomagnetic dating [PDF]

, 2011
International audienceIn the Rio Tinto district of the Iberian Pryrite Belt of South Spain, the weathering of massive sulfide bodies form iron caps, i.e., true gossans and their subsequent alteration and re-sedimentation has resulted in iron terraces, i ...

Magnetic Properties of Martian Impact Basins Including the Effect of Mantle Excavation

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The weak magnetism of many impact basins on Mars has historically been interpreted as evidence of the martian dynamo's cessation before ∼4.0 Ga. However, expected magnetic properties of these impact basins are poorly known because basin formation exhumes and recrystallizes mantle material, which has not been sampled by martian meteorites ...

Magnetic properties and natural remanent magnetization of carbonaceous chondrites containing pyrrhotite [PDF]

, 1991
Magnetic properties, NRM characteristics and magnetic minerals of four carbonaceous chondrites, the Allende, the Leoville, Y-74662 and Y-81020,are examined. These C-chondrites contain ferrimagnetic pyrrhotite grains in addition to magnetite, kamacite and/

Tracing Fluid‐Rock Interactions and Migration Pathways in Shallow Megathrust Shear Zones Through Rock Magnetic Analysis

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Megathrust shear zones are the main fluid transport pathways during the seismic cycle and play a key role in controlling physicochemical alteration. Defining fluid‐rock interaction in wall rocks provides evidence for unraveling the hydrogeology of shear zones and their link to active fluid circulation.

Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Lunar paleomagnetic studies have identified multidomain metallic Fe–Ni alloys as the dominant magnetic contributors in mare basalts. Here, we explore the low‐temperature magnetic behavior of standard samples for a suite of opaque minerals that occur within mare basalts (single‐domain and multidomain Fe, wüstite, ulvöspinel, iron chromite ...

Quantification of α-particle radiation damage in zircon [PDF]

, 2014
Analysis of radiation damage in natural mineral analogs such as zircon is important for the evaluation of the long-term behavior of nuclear waste forms and for geochronology.

Comment on “Kinetics and thermodynamics of Eu(III) adsorption onto synthetic monoclinic pyrrhotite” by Y. Zhu et al., Journal of Molecular Liquids, 218 (2016), 565–570 [PDF]

Journal of Molecular Liquids, 2016
Abstract The paper of Zhu et al. [1] is of great interest, since it reported adsorption data of Eu(III) onto pyrrhotite, an uninvestigated solid surface to date. We are of the opinion that the system is of relevance in the context of nuclear waste disposal in deep repositories.

Sulfide Mineralogy - Literature Review [PDF]

, 2010
The aim of this study was to have an insight into the sulfide mineralogy, mainly based on sulfides mineralogical studies prior to the year 1975. In the first two chapters, the metal sulfides crystal structures and chemistries are reviewed.

Ferromagnetic resonance characterization of greigite (Fe₃S₄), monoclinic pyrrhotite (Fe₇S₈), and non‐interacting titanomagnetite (Fe_3‐xTi_xO₄) [PDF]

Geochemistry, Geophysics, Geosystems, 2012
Ferromagnetic resonance (FMR) spectroscopy has become an increasingly useful tool for studying the magnetic properties of natural samples. Magnetite (Fe3O4) is the only magnetic mineral that has been well characterized using FMR. This limits the wider use of FMR in rock magnetism and paleomagnetism.
