Magnetism of Sediments, Soils, and Organisms, and How They Are Influenced by Changing Geomagnetic Fields and the Environment I, II e III

Magnetic and paleomagnetic approaches can provide unique information on mineral changes, including the origin of remanence in sediments, sediment provenance and transport, soil magnetism, magnetism of speleothems, biogeomagnetism and their bearing in tracing the variations of the Earth’s magnetic field. The integration of magnetic techniques with biogeochemical studies can therefore yield strong constraints on present and past environments on Earth and processes such as magnetism of animals (including humans), bioturbation, microbial activity, iron biomineralization, temperature, climate change, pollution, weathering, sediments transport and processes, and their effect on the magnetic signal. This session embraces contributions related to sedimentary processes, biogeomagnetism, speleothem magnetism, including the characterization of magnetic minerals and their variation through time and geomagnetic, paleoenvironmental and paleoseismicity records. Methodological advances, laboratory experiments, and new theoretical models are also included.
