NSCPHD1189 Linking seismic imaging to geodynamic modeling

Volume 2014/2015
Content

The proposed course will provide participants with an overview of the frontiers of the subject of seismic imaging of shallow and deep structure of the Earth and geodynamic interpretations of seismic models. Integration of seismic tomography models with geodynamical modeling of mantle convection, lithosphere-mantle interaction, plate tectonic processes such as subduction geodynamics, has improved the general understanding of the large-scale and small-scale geodynamic processes and provides background for understanding a series of new seismological, rheological, tectonic and dynamic interpretations of mantle (and partly crustal) properties.

 

Learning Outcome

The proposed course will include the following topics with focus on a broad geodynamic frame for seismic tomography interpretations:

1. Basic observations of Earth seismic structure

2. factors that determine seismic velocity: lithology, fabric, temperature

3. shear velocity vs temperature calibrated on oceanic lithosphere

4. seismic velocity anisotropy: how it is measured, how it is produced by deformation

5. role of density in geodynamic problems: deducing isostasy and mantle convective flow fields from tomography

6. case studies from Europe, North America, Asia

7. grand challenges to geosciences, seismic tomography modelers, and mantle dynamics. Unsolved key questions in geochemistry and geophysics in relation to the subject. How can integration of methods bring Earth sciences forward, in particular in relation to large scale tectonics, plate geodynamics, and earthquake hazards?

MS in geophysics or related disciplines
Lectures with active participation of students, student presentations, the last afternoon will devoted to a Grand Oxfordian Debate or Disputation between two teams of students.
We expect participation by PhD students in all aspects of geology, geophysics, geodynamics, numerical modeling, and geochemistry to take advantage of the course.
