Magnetic Microscopy Talk

Explore the fascinating world of magnetic microscopy in this 28-minute talk from AGU. Delve into the complexities of multi-generation magnetizations in rocks and discover the advanced tools used in geoscience, including SQUID microscopes and Quantum Diamond Microscopes (QDM). Learn about the sensitivity regimes of these instruments and their applications in studying CR chondrite magnetization. Uncover the scientific implications of field intensities during chondrule formation and how Semarkona and CR chondrites formed in distinct magnetic field environments. Investigate speleothem magnetism at various scales and gain a comprehensive understanding of this cutting-edge field in geoscience.
