Magnetic Investigation of Sedimentary Processes as a Tool to Understand Paleomagnetic Records and Past and Present Environmental Changes
Session ID#: 74925
Session Description:
Magnetic and paleomagnetic approaches can provide unique information on mineral changes, particularly in fine grained materials, and constrain the relative timing and duration of mineralogical processes during sedimentation and environmental processes.
The integration of magnetic techniques with (bio)geochemical studies can therefore yield strong constraints on several processes, including bioturbation, microbial activity, iron biomineralization, temperature, climate change, pollution, weathering, transport, deposition, dewatering, diagenesis, fluid/hydrocarbon migration, and their effect on the magnetic signal.
This session seeks contributions that focus on identifying and assessing the impact of processes that occur throughout the entire sedimentary cycle on rock magnetic, paleomagnetic and environmental records of sediments. We particularly encourage multidisciplinary contributions that combine magnetic investigations of natural records with geochemical, microbiological data and/or modeling, as well as studies using magnetic signals for reconstruction of environmental changes. Laboratory experiments, new theoretical models or measurement techniques, are also welcome.
