This course on Grand Challenges in Rock and Paleomagnetism aims to explore frontiers in rock magnetism and paleomagnetism. The course covers topics such as the role of atomic-scale properties on magnetic anomalies, using big data in rock magnetism, characterizing global geomagnetic field behavior, understanding reversals, and Phanerozoic Earth history. Students will learn about PSD behavior, vortex state fork diagrams, anomaly mapping, paleomagnetism, material properties, magnetic response, micromagnetics, and individual directions. The teaching method includes lectures by experts in the field. This course is intended for geology, earth science, and paleomagnetism enthusiasts looking to deepen their understanding of rock and paleomagnetism challenges.
