Objectives
On completion of this module, students should:- have a general overview of current ideas and models relating to Plate Tectonics/Kinematics and Mantle Dynamics;
- be capable of critical appraisal and discussion of these ideas and models. They should develop their skills of objectivity - to learn to weigh the evidence for a particular model and to distinguish between hard facts and inference or supposition;
- develop a more independent style of learning. This will involve active participation in lectures and practicals, making their own lecture notes rather than relying on structured handouts, and undertaking 3-4 hours of directed reading each week;
- improve their ability to work in a small group on a focused task to strict deadlines;
- gain experience of presenting their work at a "Conference Style" Poster session.
Syllabus
Provisional syllabus - see module handout for detailed syllabus
(A) Plate Kinematics :
- Relative plate motions; rotation vectors; relationship between rotation vector and relative motion at a point, velocity diagrams
- Rotation vectors, working out relative plate motions (magnetic anomalies, GPS, laser interferometry), plate motion circuits, finite rotations, apparent polar wander paths
- Absolute plate motions, reference frames, fault plane solutions
(B) Geodynamics:
- Mantle structure and dynamics; 410 km, 660 km and D" discontinuities; compositional versus thermal convection, and the existence of mantle plumes. Geophysical and geochemical constraints on the nature of mantle convection
- Heat flow and heat generation in the Earth. How hot is the mantle? The adiabat and the geotherm; thermal subsidence and mid ocean ridges
- Subduction zone processes: stresses and earthquakes in subducting slabs; olivine phase changes; earth quake mechanisms; types of melt (Island arc tholeites, andesites, boninites, adakites); thermal modelling, dehydration and slab melting
- Construction of oceanic crust; slow vs fast spreading
- Comparative subductology; back-arc basins, plate coupling; slab roll-back; absolute plate motions; comparison of IBM and Andean subduction systems
- Plate driving forces
(C) Poster presentation:
- Combination of private study and group work, plus 1x 2 hour conference style Poster Session. This will develop the ideas and understanding of Part A of the module.
