Objectives and Content
The course aims to give students the necessary background to be able to use and critically assess paleomagnetic methods in different applications such as plate tectonics, environmental magnetism and geochronology. Principles for sample collection, determining magnetic mineral content and remanence vectors, as well as statistic treatment and interpretation of results in a geological context will be discussed. The course also covers the principal naturally occurring ferromagnetic minerals, and how their magnetization is influenced by geological factors such as temperature history, chemical changes and grain size. The subject matter is illustrated through application examples and the use of relevant software.
After completing the course GEOV312 the student should be able to:
- explain the occurrence, composition, structure and magnetic properties of the most common magnetic mineral phases
- Discuss how different geological factors affect the magnetic properties of rocks and sediments
- Use available computer tools to visualise, analyse and interpret paleomagnetic data
- Carry out directional analysis on rock specimens with multicomponent remanent magnetisations, and use Fisher statistics and paleomagnetic field tests to judge the uncertainty in a magnetic components direction and age
- Discuss the reliability of a paleomagnetic study based on given quality criteria, and interpret results in a geological context
