Geodynamics - Shaping Earth’s Surface

Course content

The course starts with a review of the evidence of horizontal and vertical motions of Earth’s lithosphere, and continues with a look at the constitutive equations of Earth’s mantle viscous convection, and how one can draw important first-order features of the lithosphere from simple handling of these equations. The course continues with a focus on observations (e.g., gravity anomalies, paleo-altimetry data, etc.) that allow us to infer the shape of Earth’s surface and its possible past development.

 

The course also features a quantitative, real data-driven project on how isostasy and elasticity of the Earth’s lithosphere determine the support of large topographic features over geological time. Such a project allows students to familiarize themselves with real data set as well as with computational tools (e.g., Matlab, Python) often utilized in the industry.

 

In addition to geology students, this course will be certainly of interest to students and NBI, since the description of the processes shaping Earth’s surface is done in the context of the laws of physics and thermodynamics. Students in geography may also have an interest in the long-term shape of Earth’s surface, as it provides a context for more specific studies in, among others, geomorphology and sea-level evolution.

Education

MSc Programme in Geology-Geoscience

Learning outcome

Knowledge

  • Kinematics and dynamics of Earth’s mantle and lithosphere.
  • Plate motions.
  • Gravity anomalies.

 

Skills

  • Handle quantitative problems related to mantle/lithosphere dynamics and kinematics.
  • Handle large geophysical data sets using computational tools. The overarching goal is to enable students to extract inferences of geological value from the analyses of geophysical data sets by using theory, mathematical/statistical approaches, and computational tools.

 

Competencies

This course aims at enabling students to understand and study:

  • how mantle/lithosphere dynamics at the global scale shape the Earth’s surface over geological time-scales through horizontal (i.e., plate motions) and vertical (i.e., glacial rebound, dynamic topography) movements; and
  • the context in which many of the geological processes already seen, or to be seen, in other courses (e.g., basin formation and evolution, geochemistry of the crust, evolution of ocean circulation over geological time-scales, glacial rebound and coastal evolution etc.) occur.

Class lectures, class exercises, homework assignments, data-driven individual project.

Please see Absalon course page.

BSc in Geology-Geoscience or equivalent is recommended. In order to participate, students are expected to be particularly familiar with the geophysical notions covered in Introduction to Quantitative problem-solving in Geosceinces and Andvendt geofysik i geovidenskab (BSc curriculum), as well as Integrating fundamental concepts in geosciences (MSc curriculum).

This course contains elements that fall into the categories of Digitalisation, Quantitative methods, Statistics.
