| Summary | Structural geology and rock deformation affect a large number of economic, environmental and societal interfaces with planet Earth, and the response of rocks to plate motions shapes our planet¿s appearance. This course will teach not only a fundamental knowledge of the parameters that govern the relationship between stress and strain but put the rock response into a perspective that seamlessly ties in with material taught in related courses.
This course reverses the theory-first/application-second approach of all common structural geology textbooks by introducing students to the structural geology of regions they are either familiar with, or have heard of. The regions are chosen so that a) in sum, they represent all important deformation processes and styles, b) the students will/may visit them, c) excellent (teaching) material is available or can be organised to allow for a true multi-scale and integrated assessment using a wide range of data and d) the lecturers know them well. Students will experience key quantities, concepts and descriptors of rock deformation through a large variety of structural and geospatial datasets acquired from deforming rocks and regions. The nature of structural geology requires that these datasets are collected on multiple scales, from that of crystal lattices to that of entire continents, and the course honours these requirements.

| Additional Information (Assessment) |
The course will be assessed through an ArcGIS-based project in which students will analyse and synthesise structural and geospatial datasets from one of the regions studied in the lectures. We anticipate the students to work about 75 hours on this. This will contribute 60% to the final mark. These projects will be produced in groups of three. Half of the project mark will be on the group result, individual students will be responsible for the intergration of particular kinds of data. These contributions will contribute the other half to the project mark.«br /»
«br /»
40% will be contributed through an exam. To pass the course, students need to obtain at least 40% on each component.«br /»

Learning Outcomes
On completion of this course, the student will be able to:
- Develop an in-depth understanding of the link between plate motions and rock response along plate boundaries both in terms of mineralogy, rock fabrics and fluid transport properties
- Learn to link plate tectonic processes with the associated development of topography
- Develop skills in visualising map and related field data in three dimensions using appropriate graphical techniques
- Develop an appreciation of the degree of uncertainty of the data collection methods and the relationship between surface and subsurface data.
- Develop skills in synthesising the geology of an area through the integrated use of maps, cross-sections, diagrams and accompanying reports.
