GEOS645 Physics & Chemistry of Mountain-Building
- Be able to describe the fundamental concepts of heat flow, diffusion and mass tranport in the Earth.
- Be able to apply thermodynamic and kinetic principles to model heat flow and diffusive processes.
- Utilize both spreadsheets and Matlab to compute analytical and numerical solutions to the heat flow and diffusion equations.
- Be familiar with sources of scientific information and be able to utilize scientific literature dealing with orogenesis.
This course is designed to be an introduction to modern methods for analyzing the pressure-temperature-time paths and histories of metamorphic terrains comprising modern and ancient mountain belts; subjects to include quantitative geothermobarometry, chemical diffusion and closure temperature theory, geochronology and thermochronology, the thermal structure and evolution of mountain belts.
- Projects (3; poster, presentation, paper) 75%
- Class discussion & participation (including paper summaries) 25%
