| Summary | Plate tectonic processes play an important role in the distribution of rock types on the surface of the Earth. This course analyses the physical processes responsible for the formation and destruction of tectonic plates. It considers the principle tectonic components of the Earth such as mid-ocean ridges, subduction zones and mountain ranges, and develops an understanding of the specific rock types formed in these environments. The course also considers the mechanisms by which sediment is generated as a result of the tectonic processes is analysed, as well as processes on in-situ sediment production. Sediment formation and transport processes are studied as well as the sediment and rock types that are generated. We then demonstrate how sedimentary rocks are used to reconstruct ancient tectonic and other environments.
Practicals and a weekend field trip will develop concepts from the lectures.

Feedback
Practicals (non-assessed): Students will be able to get help and feedback on their practical work during scheduled practical sessions, or at other times upon request to the course organiser/lecturers.
Course work: Students will receive written feedback on work (both assessed and non-assessed) which is handed in during the course.
Individual Meetings: Students can arrange individual meetings with the CO/lecturer at any time for advice, feedback etc.
End of semester exams: Students will be able to view their corrected manuscripts upon request, and discuss their results with the course teaching team.

Learning Outcomes
On completion of this course, the student will be able to:
- Explain modern tectonic theory and plate tectonic processes.
- Interpret and explain major features of current and past tectonic activity, and the geological processes involved.
- Understand the mode of formation of igneous, metamorphic and sedimentary rocks in the context of global tectonics and the ability to identify and interpret them under a petrological microscope.
- Analyse sedimentary successions in the laboratory and the field and the criteria used to reconstruct ancient sedimentary environments.
- Understand surface, biological and chemical processes involved in the generation and transport of siliciclastic sediments (eg. Sands) and carbonates (eg. limestones and dolomites) over the globe, and their plate tectonic association.
