Session Proposal: Environmental Magnetism (AGU25)

GP004
Environmental Magnetism

Session ID#: 246883

Session Description:
Environmental magnetism is used to characterize and investigate geologic, anthropologic, and biogeochemical processes and histories. Interpretation of these signals requires an understanding of how magnetic minerals form, partition, and interact with their surroundings and how they are preserved, altered, and are affected by microbiology and abiotic reactions in their archives. This session is a celebration of the many ways magnetic minerals are used to understand the world around us. We welcome submissions on all aspects of environmental magnetism from all kinds of archives including, but not limited to, studies of weathering, erosion, deposition, diagenesis, paleoclimate/paleoenvironments, magnetofossils, pedogenesis, and air and soil pollution. We particularly encourage multidisciplinary contributions that combine magnetic investigations of records with independent geological, geochemical, microbiological, modeling, and/or microscopic constraints. Laboratory experiments and cultures, new theoretical models, unmixing approaches, and innovative analytical techniques (including the use of AI) to solve key environmental magnetism issues are also welcome.
