Objectives and Content

Objectives:
The course gives an introduction to quantitative geodynamics. The overall goal of this course is to provide the students with a good understanding of geodynamics and surface processes. A first sub-goal of this course is to provide the students with an intermediate level of understanding of geodynamic processes of the solid earth plus programming skills in computational methods. A second sub-goal of this course is for the students to learn how to do a literature study on a topic in geodynamics and/or surface processes.

Content:
In the first part, a brief overview of plate tectonic processes is given. The equation for thermal energy balance for the lithosphere is developed, and it is shown how the equation may be applied on various geological models and processes. Vertical movements expressed as uplift or exhumation and the concept of isostasy and flexural strength are then examined. The mechanics of the crust and lithosphere deformation is covered including a discussion of plate driving forces, the rheology of the lithosphere, elastic, brittle and viscous deformation processes. The response of rocks to applied forces is discussed and modelled. Dynamic processes including lithosphere extension, basin formation, and continental collision are discussed. Lastly the course gives an introduction to quantitative geomorphology, erosion models for orogenic scale landscape evolution including both short and long range transport mechanisms. The course uses Matlab to calculate and visualise the evolution of temperature, strength, basin subsidence, and surface erosion for simple cases.

Learning Outcomes

n completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge
The student can

  • solve the heat equation for simple geologic problems
  • create Matlab programs to calculate temperature and heat flow for various geological scenarios and to calculate dependent strength within the lithosphere
  • explain Eulerian and Lagrangian reference frames
  • explain the concepts of uplift, subsidence, burial, exhumation, denudation
  • explain local and regional isostasy, and solve simple isostatic problems related to erosion and sedimentation
  • describe the basis for the equation showing depth of the oceans as function of age
  • describe the McKenzie rift model, and explain the concepts crust and mantle stretching factors, backstripping, tectonic, thermal, and isostatic subsidence
  • explain fundamentals of stress and strain
  • explain what controls the rheology of the oceanic and continental lithosphere
  • explain erosion models at an orogenic scale, and short and long term transport mechanisms
  • know how to conduct a literature study on a topic on computational geophysics and/or a small research project
  • use tools from the library as well as online tools for this project in computational geophysics

Skills
The student can

  • write computer programs in Matlab to illustrate and solve scientific problems in geodynamics and surface processes
  • write a short scientific paper on a topic of relevance in computational geodynamics and/or surface processes
