Fluid und Magmatransfer

Background

Fluid and magma migration in the lithosphere and crust play a crucial role in the geodynamics of our planet and in the birth and evolution of volcanic systems. Fluid and magma migration transport heat and mass, contribute to the formation of ore deposits, and can drive volcanic eruptions and seismic activity. The pathways taken by fluids and magma are controlled by a complex interplay of factors, including the physical properties of the host rocks, the stress field, and the buoyancy forces driving the migration. Deriving a better understanding of these controls is essential for interpreting the geophysical observables generated during fluid movement, such as earthquake swarms, seismic long period events, ground deformation, gravity changes. Improved knowledge of fluid and magma pathways also enhances our ability to assess volcanic and seismic hazards.

Key scientific questions

  • What are the primary geological and physical controls on the pathways of fluid and magma migration in the lithosphere and crust?
  • How do variations in magma and fluid properties influence migration dynamics and associated geophysical observables?
  • What are the key observables generated by migrating fluids and magma, and how can they be used to better understand volcanic and seismic activity?
