Fundamental Studies in Rock and Mineral Magnetism
Session ID#: 76427
Session Description:
Rock and mineral magnetism are the foundations for an ever-increasing array of geoscience applications and are fundamental to our understanding of natural systems. This session brings together a broad range of advances in rock magnetism including experimental and analytical methods, development of our knowledge of fundamental rock magnetic properties, proof-of-concept studies linking magnetic properties to natural processes using control experiments, and the development of new instrumentation. We welcome contributions focusing on fundamental rock magnetism, numerical modeling of magnetic phenomena, magnetic behavior of nanoparticle systems, biomagnetism, particulate matter (PM2.5 and PM10), and magnetic microstructures. Theoretical and experimental studies aimed at resolving open questions are particularly welcome, including accurate and efficient paleointensity determination, the origin of magnetic anisotropy in ferromagnetic particles, and lock-in mechanisms during acquisition of magnetization. We encourage contributions using well-characterized synthetic or natural samples to investigate fundamental magnetic behavior or demonstrate the validity of new methods.
