Environmental magnetism is a key tool for characterizing, discriminating, and interrogating litho- and bio- geochemical processes occurring both on Earth today and in the past. Our ability to interpret environmental change continues to improve through a better understanding of how magnetic minerals are formed, partition, and interact with their surroundings, and how they are preserved in marine, aqueous, and (sub)surface environments. We welcome submissions on all aspects of environmental magnetism including, but not limited to, studies of pollution, weathering, deposition, diagenesis, paleoclimate/paleoenvironmental reconstruction, biogenic magnetic phases, and microbial activity. We particularly encourage multidisciplinary contributions that combine magnetic investigations of natural records with independent geological, geochemical, microbiological, modeling, and/or microscopic data. Laboratory experiments and cultures, new theoretical models, unmixing approaches, and innovative analytical techniques are also welcome.
