Low-field variation of the anisotropy of out-of-phase susceptibility of pyrrhotite-bearing rocks and its implications for rock fabric studies

Key Points

• Higher anisotropy indicates distinct variations in out-of-phase susceptibility, revealing information about rock fabric.
• The study found that the anisotropy of out-of-phase susceptibility can significantly vary in pyrrhotite-bearing rocks over low-field conditions.
• Observational analysis highlights the link between low-field variation in susceptibility and rock fabric characteristics.
• Understanding this anisotropy supports improved geological models, aiding in resource exploration and rock property assessments.
