Environmental Magnetism

Session ID#: 157534

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, interact with their surroundings, and are preserved 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 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 are also welcome.
