Geodynamic and Plate Tectonic Principles

Lecturers: Karsten Gohl

Content:

This modul teaches the geodynamic and geophysical fundamentals of plate-kinematic and plate-tectonic processes on Earth. This includes an understanding of the major geodynamic cycles from crustal generation at divergent plate boundaries of oceanic and continental rifts to crustal accretion and subduction at convergent plate boundaries, including the underlying driving mechanisms and forces. All components of this cycle will be investigated by assessing geophysical evidence. The students will learn about the geometrical principles of plate-kinematics and apply these in practical exercises. They will learn to visualize, apply and test plate reconstructions by using the software GPlates. In addition to the lecture and exercises, the students will select individual project topics to focus on particular regions or geodynamic processes of interest and will present an oral and written report.

Competences:

(1) Understand fundamental geodynamic processes from the core to crust;
(2) Apply plate-kinematic principles for regional and global tectonic reconstructions;
(3) Analyse geophysical evidence for tectonic plates types, plate boundaries and crustal characteristics from crustal generation to subduction;
(4) Use specialized software (GPlates) to test existing and generate new plate-tectonic motion models

Assessment:

The students will select individual project topics to focus on particular regions or geodynamic processes of interest and will present an oral and written report. The oral presentation of 15 minutes and the written report of 5-6 pages (plus figures and references) will each count 50 percent of the final grade for this module.
