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, supplemented by reading assignments, will illustrate how field observations can be used to reconstruct tectonic environments in ancient mountain belts. We will also use journal articles to explore ways in which plate tectonics help explain the evolution of mountain belts with special emphasis on the Appalachians.
