Paleomagnetic and rock magnetic methods applied to volcanology
Paleomagnetic and rock magnetic methods applied to volcanology
Session ID#: 123190
Session Description:
Paleomagnetism and rock magnetism are powerful tools for studying volcanic processes. Magnetic fields recorded by lava or pyroclastic flows can provide emplacement age estimates. Remanence and rock magnetic properties can act as a cross-correlation tool between different units. Anisotropy of magnetic susceptibility can constrain subsurface magma flow directions as well as surface lava and ignimbrite flow dynamics. Paleomagnetic methods can thereby assist in refining spatiotemporal models of volcanoes and volcanic complexes. Additionally, progressive thermal demagnetization can help distinguish between hot and cold deposits and provide emplacement temperatures estimates - both important for hazard assessment. Magnetic techniques have revealed many aspects of volcanoes, but many more revelations are anticipated. We welcome contributions on the recent advancements in utilizing paleomagnetism and rock magnetism to study volcanic processes and materials.
