Class Details

Fifty years after the sea-floor spreading hypothesis was first verified using magnetic anomalies, we have spectacular data sets from paleomagnetism, seismology, volcanism, the Global Positioning System, and digital elevation models that provide rich details into the kinematics and mechanisms of present and past plate motions. After an introduction to the theory of plate tectonics, local field trips will illustrate how field observations can be used to reconstruct tectonic environments in ancient mountain belts. Digital elevation models integrated with geologic maps and cross-sections will be used to construct 3D models. We will also explore ways in which tectonics, climate, and erosion affect each other during the evolution of mountain ranges. Class meetings will include lectures and discussions of assigned reading. Labs will include field trips and computer-based projects.
