Mantle convection is the fundamental agent driving many of the geological features observed at Earth's surface, including plate tectonics and volcanism. However, many geologists have an incomplete understanding of the process, whilst there are many misconceptions about how it relates to surface processes. A broad background to the physics and fluid dynamics of mantle convection will be provided in this course, by explaining what it is, how it works, and how to quantify it in simple terms. It assumes no specialist background: mechanisms will be explained simply and the required basic physics will be fully reviewed and explained. The distinctive forms that convection takes within Earth's mantle will be described within the context of tectonic plates and mantle plumes, whilst the implications for geochemistry and Earth's tectonic evolution will be explored. Common misconceptions and controversies will be addressed, providing a straightforward, but rigorous, explanation of this key process. Emerging insights into the fundamental links between climate, surface processes (weathering, erosion and sediment transport), plate tectonics and underlying mantle flow will also be covered, thus providing a complete overview of Earth’s dynamic engine.
Upon successful completion, students will have the knowledge and skills to:Upon completion of this course, students will have the skills and knowledge to:
- Understand the principles of convection and demonstrate how these principles apply in the Earth’s mantle.
- Solve a range of geodynamic problems, including an understanding of uncertainties involved .
- Quantify the force-balance driving plate tectonics and the implications for the structure of Earth's interior,as imaged by seismology and illuminated via geodesy.
- Make robust inferences about mantle convection drawn from observations, thus connecting mantle convection to surface processes, geology and geochemistry.
- Formulate areas for their own future research, while critically reading and analysing scientific literature.
- Demonstrate effective written and oral presentation skills to a variety of audiences.
Indicative AssessmentAssessment will be based on:
- In class assessment during practicals: 40% (LO 1-6).
- Oral presentations: 10% (LO 6).
- Written lay descriptions: 10% (LO 6).
- Final examination: 40% (LO 1-6).
The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
Workload2 hours of lectures and a 3-hour practical per week. An additional 65 hours is expected to be spent outside ofclass preparing for practicals and completing coursework.
